PPGLayout Class Reference

Detailed Description

The PPGLayout object represents the visual appearance of an object's state when it is inspected. (PPG is a common acronym for Property Page). The layout makes it possible to group objects together, use special controls, hide obsolete parameters, add Buttons and in general create a presentation of an object's state that is pleasing to the eye.

A PPGLayout is modeled in Softimage as a linear list of PPGItem objects. Each PPGItem represents either a parameter in the inspected object, or a special UI item like a Tab or Button. In most cases the layout does not specify hard-coded pixel positions or dimensions for the PPGItems. Instead, Softimage automatically draws the controls with a sensible layout. This allows the presentation to change in a pleasing manner when the user resizes the property page. However there is some support for providing hints, for example PPGItem::PutWidthPercentage, or even explicit sizes via PPGItem::PutAttribute.

Many different controls are available for use on a property page, see ::siPPGControlType. All controls can be added using PPGLayout::AddItem but convenience functions are provided for some of the most common controls, for example PPGLayout::AddColor.

Practically every built-in Softimage object has its own layout. However, if there is no specific layout, Softimage displays a default layout that lists all the parameters in a simple fashion.

Layouts are remembered in memory while Softimage is running. The layouts for built-in objects are reloaded from SPDL files when Softimage restarts. The layout for a CustomProperty object implemented as a PluginItem is defined by implementing the cb_Property_DefineLayout DefineLayout callback.

You cannot directly modify an existing layout structure, apart from adding new items at the end or changing the attributes of items already in the layout. However to modify a layout it is often reasonable to call PPGLayout::Clear and then rebuild the entire layout with the changes included. You can also hide parameters without removing them from the layout by setting the siNotInspectable flag (see Parameter::PutCapabilityFlag).

Note:
If the layout is changed from within the PPGEvent callback it is necessary to set the Refresh attribute to see the changes take effect. (see PPGEventContext).

Normally the layout is associated with an object that remains in the scene. However it is also possible to use this object to define the user interface of a temporary dialog box. For example a script can ask the user to specify some import or export options. This is done in conjunction with a temporary CustomProperty object and the InspectObj command.

Parameters:
in_refconstant class object.
Returns:
The new PPGLayout object.
PPGItem AddItem ( const CString in_ParamName,
const CString in_Label = CString(),
const CString in_Type = CString() 
)

Adds a control to the PPGLayout. Normally this new item represents a parameter on the object that is inspected, and allows a user to view and change its value. For example this function can be used to add a Slider control which shows the value of a numeric parameter on a CustomProperty.

It is possible to add any kind of control using this function. However convenience functions such as PPGLayout::AddColor have been added for some of the most common controls.

Often a call to this function is followed by one or more calls to PPGItem::PutAttribute to provide additional information about the appearance of the item.

Parameters:
in_ParamNameScripting name of the Parameter. The call does not fail even if no parameter by this name exists. However in that case the control is not drawn as part of the layout. (See PPGItem::GetName).
in_LabelMost controls have a label, for example the text that appears to the left of a numeric slider. If not specified here, the value returned from SIObject::GetName or Parameter::GetScriptName is shown instead. (See PPGItem::GetLabel).
in_TypeSpecify the control to draw. A complete list of possible controls is listed in the siPPGControlType string constants. For example this argument can be used to specify that a parameter should be displayed as a combo box. (See PPGItem::GetType). If not specified, Softimage uses a simple heuristic for determining what control to use, based on the Parameter::GetValueType. For example, strings have an edit control, numeric types like float and integer use a slider, and boolean parameters use a checkbox.
Returns:
The newly created PPGItem.

PPGItem::GetLabel, Parameter::GetScriptName, cus_ppg_PropertyPageControls Property Page Controls
PPGItem AddString ( const CString in_ParamName,
const CString in_Label = CString(),
bool  in_Multiline = false,
LONG  in_Height = 120 
)

Adds a string to the PPGLayout. This is very similar to PPGLayout::AddItem but it makes it easier to specify a multi-line string control.

Parameters:
in_ParamNameScripting name of the Parameter. The call does not fail even if no parameter by this name exists. However in that case the control is not drawn as part of the layout. (See PPGItem::GetName).
in_LabelMost controls have a label, for example the text that appears to the left of a numeric slider. If not specified here, the value returned from SIObject::GetName or Parameter::GetScriptName is shown instead. (See PPGItem::GetLabel).
in_MultilineWhen True, the value of the string parameter is represented with a multi-line edit control. This control is useful for allowing users to write script code or free form text. And, when the control is read-only, it is useful for showing detailed instructions to a user. The control supports scroll bars in the cases where text is larger than the control's width or height. A multi-line edit has siControlEdit as its PPGItem::GetType and uses the siUICX, siUIStyle and siUIClass attributes (see PPGItem::GetAttribute).
in_HeightThis parameter only applies when the MultiLine argument is true. It specifies the height, in pixels, of the multi-line control.
Note:
It is not necessary to set the width because the control automatically resizes according to the size of the property page.
See also:
PPGLayout::AddItem, cus_ppg_MultilineText Multi-line Text controls
Example:
        using namespace XSI;
        Application app;
        Model root = app.GetActiveSceneRoot();

        CustomProperty oPSet ;
        root.AddProperty( L"CustomProperty", false, L"DescriptionPSet", oPSet) ;

        Parameter oParam ;
        oPSet.AddParameter( L"Description", CValue::siString, siPersistable, L"",L"",L"", oParam ) ;
        oPSet.GetPPGLayout().AddString( L"Description", L"", true, 200l ) ;
        oPSet.PutParameterValue( L"Description", CValue( L"Here is some\r\n\tmulti-line text" ) ) ;

        CValueArray args(5) ;
        args[0] = oPSet ;

        CValue retval = false ;
        app.ExecuteCommand( L"InspectObj", args, retval ) ;
PPGItem AddEnumControl ( const CString in_ParamName,
const CValueArray in_UIItemsArray,
const CString in_Label = CString(),
const CString in_UIType = CString(L"Combo") 
)

This is similar to PPGLayout::AddItem except it makes it easy to specify enumeration style controls like ::siControlCombo, ::siControlRadio, and ::siControlIconList. These are controls which restrict the values that a users can set on a Parameter by offering a specific list of valid values. Any numeric or string parameter type can be driven by these controls.

Parameters:
in_ParamNameScripting name of the Parameter. The call does not fail even if no parameter by this name exists. However in that case the control is not drawn as part of the layout. (See PPGItem::GetName).
in_UIItemsArrayA 1-Dimensional array of Label/Value pairs. Each label is a CValue containing a CString and the value is a CValue whose type should match the Parameter::GetValueType of the associated Parameter. For example, for a bitfield, the array might contain ( L"Bit 0", 1l, L"Bit 1", 2l, L"Bit 2", 4l ).
in_LabelMost controls have a label, for example the text that appears to the left of a numeric slider. If not specified here, the value returned from SIObject::GetName or Parameter::GetScriptName is shown instead. (See PPGItem::GetLabel).
in_UITypeSpecify the control to draw. A complete list of possible controls is provided in the siPPGControlType string constants, but in the case of this function only certain controls, such as ::siControlCombo, ::siControlRadio, ::siControlCheck, and ::siControlIconList are supported.
See also:
PPGLayout::AddItem, PPGItem::GetUIItems, cus_ppg_EnumControls Enum Controls
PPGItem AddColor ( const CString in_RedComponentParamName,
const CString in_Label = CString(),
bool  in_Alpha = false 
)

This is similar to PPGLayout::AddItem but it helps add a color widget to a layout. There are two variations of the Color widget, ::siControlRGBA and ::siControlRGB. Rather than a single parameter, this control reads and writes a separate parameter for each "channel" of the color.

To successfully create an RGBA color control on a CustomProperty, first add four siDouble or siFloat parameters to the control, for example MyR, MyG, MyB, and MyA. The naming scheme is not important but the parameters must be consecutive. This parameters should have a UI Range of 0 to 1 because the values are stored in normalized format. However you can have a larger actual Range if you want to support colors outside the normal color space. (See Parameter::GetSuggestedMax and Parameter::GetMax).

The default control for a siDouble parameter is ::siControlNumber, but the color widget can be displayed instead by calling this method and specifying the name of the first parameter, for example MyR. To read the color value through the object model, just refer to the values of the four parameters, for example MyG will contain the normalized green component of the color.

Note:
Shaders support colors directly as a native "strong" type. So rather than having multiple parameters of type siDouble or siFloat, they use a single parameter of type "Color".
Parameters:
in_RedComponentParamNameScript Name of the Parameter that represents the Red component of the color. The names of the Green, Blue and optional Alpha parameters do not need to be specified because Softimage uses the parameters that are consecutive after the Red component.
in_LabelSpecify the text which appears to the left of the Color Widget. If not specified here, the value returned from SIObject::GetName or Parameter::GetScriptName appears instead. (See PPGItem::GetLabel).
in_AlphaSpecifies whether the color should include an Alpha channel. This argument decides whether a ::siControlRGBA or ::siControlRBG is created.
See also:
cus_ppg_RGBColorControl RGB Color Control , cus_ppg_RGBAColorControl RGBA Color Control
PPGItem AddButton ( const CString in_ScriptName,
const CString in_Label = CString() 
)

Adds a button to a layout. Unlike other controls a button doesn't have to be associated with any particular Parameter on the inspected object. Instead it basically serves the purpose of executing some logic when pressed.

By default, the width of the button is automatically determined based on the text of the Label. However this can be overridden with the ::siUICX attribute. (See PPGItem::PutAttribute)

Parameters:
in_ScriptNameA unique name for the button, which should not contain any space characters. This name is used to determine the logic subroutine to call when the button is pressed.
in_LabelLabel of the button. If not specified then the ScriptName is displayed.
See also:
PPGLayout::PutLogic, PPGLayout::AddItem, cus_ppg_CommandButton Command Button
PPGItem AddFCurve ( const CString in_ScriptName,
LONG  in_Height = 300 
)

Adds an FCurveEditor to the layout. It should be associated with an FCurve Parameter (see CustomProperty::AddFCurveParameter). This control is a full FCurve editor, and should not be confused with the Animation Divot.

Like other Parameters you can add custom Logic code to the PPGLayout that is called whenever the FCurve changes.

Parameters:
in_ScriptNameScripting name of the Parameter, which must be of type FCurve. The call does not fail even if no parameter by this name exists. However in that case the control is not drawn as part of the layout. (See PPGItem::GetName).
in_HeightHeight of the control.
Note:
It is not necessary to set the width because the control automatically resizes according to the size of the property page.
See also:
CustomProperty::AddFCurveParameter, FCurve, PPGLayout::GetLogic, cus_ppg_FCurveWidget FCurve Widget
PPGItem AddStaticText ( const CString in_Text,
LONG  in_Width = 0,
LONG  in_Height = 0 
)

Static text is read-only text which appears directly on the property page. It is similar to the label of a parameter but it is not associated with any parameter. It is a useful control for adding basic documentation directly in the user interface. Use line breaks (\n) in the text to force the text onto multiple lines.

Note:
It is also still possible to read the text for a static control from a value of a string parameter, by using :::siControlStatic (see the ::siPPGControlType string constants). However this function is easier and more efficient because it does not require any associated Parameter.
Parameters:
in_TextText to display. This can be changed afterwards by calling PPGItem::PutLabel.
in_WidthWidth of the text (in pixels). If not specified, the text will use the entire width of the Property Page and will not word wrap even if it does not fit.
in_HeightHeight of the text. If not specified, the text's height is calculated based on the number of lines of text.

cus_ppg_StaticText Static Text

4.2
PPGItem AddSpacer ( LONG  in_Width = 0,
LONG  in_Height = 0 
)

Use this function as a tool for fine tuning the layout of a property page. It supports the insertion of blank space onto the layout. The most basic usage is to provide just a height value and to create a horizontal band of blank space. It can also be used to control the horizontal placement of other controls that are part of the same row.

Parameters:
in_WidthWidth of the spacer (in pixels). It is only necessary to specify this value when there are other controls in the same row.
in_HeightHeight of the text. If not specified the spacer will be a standard control height (22 pixels)
Since:
4.2
CStatus Clear ( )

Flushes the current layout, removing all PPGItems. The normal use for this function would be to flush any existing layout right before defining a new layout. This function differs from PPGLayout::Delete in that it does not erase the complete layout, so attributes like the logic code are maintained (see PPGLayout::PutLogic and PPGLayout::PutAttribute). If no new items are added to the layout after calling PPGLayout::Clear then the Property Page will be empty.

See also:
PPGLayout::Delete, cus_ppg_DynamicallyChangingCustomProperties Dynamically Changing Custom Properties

Reimplemented from CBase.

CStatus Delete ( )

Deletes the entire layout, including all PPGItems, logic code and other PPGLayout attributes. If no new items are added to the layout after calling Delete then the Property Page appears with a default layout, showing all the parameters in the order they were created.

See also:
PPGLayout::PutAttribute, PPGLayout::PutLogic, PPGLayout::Clear, cus_ppg_DynamicallyChangingCustomProperties Dynamically Changing Custom Properties
CStatus AddRow ( )

By default each item on a layout is drawn below the previous element. However, sometimes it is desirable to save space by putting multiple items on the same row. This function lets you start a row of controls. All groups, parameters, buttons or other items added after this call will appear on the same horizontal row until PPGLayout::EndRow is called.

This function is provided for convenience when creating the layout for an object. Internally Softimage does not create PPGItem objects to represent when a row begins or ends. Instead it uses the continue flag (see ::siUIContinue).

See also:
PPGLayout::EndRow, PPGItem::PutAttribute, cus_ppg_WrappingControlsRows Wrapping Controls (Rows)
CStatus EndRow ( )

Completes a row that was opened by a previous call to PPGLayout::AddRow.

See also:
PPGLayout::AddRow, cus_ppg_WrappingControlsRows Wrapping Controls (Rows)
PPGItem AddGroup ( const CString in_Label = CString(),
bool  in_ShowFrame = true,
LONG  in_WidthPercentage = 0 
)

Adds a group to the layout. A group can be used to draw a box around related items, or as a way of arranging controls into columns. It is possible to nest groups.

Groups are represented in the layout with two special PPGItem objects, one for the beginning of the group and the other for the end. Hence to change a label on a group it would be possible to enumerate through the PPGItems to find the item associated with the beginning of the group and to call PPGItem::PutLabel.

Parameters:
in_LabelWhen specified, the label is shown and a frame is drawn around the group.
in_ShowFrameFlag whether to draw a frame around the items in the control. When a label is specified a frame is always drawn (see ::siUIShowFrame).
in_WidthPercentageThis parameter is only applicable if the group is part of a row. It describes how much of the horizontal space should be taken by this group. If not specified, Softimage uses its own heuristic to lay out the group. For example, it might look better to split two groups 30%/70%, rather than using even spacing, if the second group has wider controls than the first.
See also:
PPGLayout::EndGroup, PPGItem::GetWidthPercentage, cus_ppg_GroupingControls Grouping Controls
PPGItem EndGroup ( )

Completes a group that was opened by a previous call to PPGLayout::AddGroup.

See also:
PPGItem::AddGroup, PPGItem::GetWidthPercentage, cus_ppg_GroupingControls Grouping Controls
PPGItem AddTab ( const CString in_Label)

Starts a new tab on a layout. This allows a complex object to be represented on multiple "pages", rather than creating a very tall property page.

This should be the first item added to a multiple-tab layout. If a layout only has a single tab then the tab control does not show up.

Note:
No EndTab function is necessary on PPGLayout. A tab is recognized as being complete when a new tab is started or the end of the layout is reached.
Parameters:
in_LabelThe text that appears in the tab control.

cus_ppg_UsingMultiplePagesTabs Using Multiple Pages (Tabs)
CStatus SetViewPosition ( LONG  in_posX,
LONG  in_posY 
)

CStatus GetViewSize ( LONG &  out_width,
LONG &  out_height 
) const

Returns the view size, which may (but isn't guaranteed to) be used by the PPG containing the layout to determine the PPG's size. This is currently only supported in modal PPGs.

Parameters:
out_widthThe width of the size
out_heightThe height of the size
Returns:
OK on success; error code on failure.

CString GetLogic ( ) const

Returns the script code, if any, associated with the PPGLayout. This script code contains subroutines to react to events in the property page. This property corresponds to the text found in the BeginScript/EndScript section (or equivalent Logic section) of a SPDL file.

Returns:
Contents of the script code associated with the Layout.
See also:
PPGLayout::PutLogic, cus_ppg_DynamicallyChangingCustomProperties Dynamically Changing Custom Properties
CStatus PutLogic ( const CString in_strLogic)

Sets the script code associated with the PPGLayout logic. This script code contains subroutines to react to events in the property page. This property corresponds to the text found in the BeginScript/EndScript section (or equivalent Logic section) of a SPDL file.

The provided string must be a correctly-formed script, written in the language specified in the PPGLayout::GetLanguage section. The script is not tested for syntax errors at the time this call is made.

The logic script consists of subroutines implemented in any of the supported Scripting Languages. A routine named "OnInit", if defined, is called when the PPG first loads. To react to a parameter changing, create a routine named "PARAMSCRIPTNAME_OnChanged". To provide script code that gets executed when a button is pressed, create "BUTTONNAME_OnClicked". In all these routines a global instance of the object PPG is available to get context information.

This property makes it possible to still have property page event handling on a custom object even when there is no associated SPDL file. For example it would be possible to read a script file into a string and provide it as the value of this property.

Rather than using this method to embed script code directly in the PPGLayout, it is also possible to specify an external file, using the ::siUILogicFile attribute. See PPGLayout::PutAttribute.

It is not necessary to set this Property for a CustomProperty that is based on a PluginItem. In that case it is possible to write the event handling callbacks directly in the same script file or dll that implements the Plugin.

Parameters:
in_strLogicContents of the script code associated with the Layout.
See also:
PPGLayout::GetLogic, cus_ppg_DynamicallyChangingCustomProperties Dynamically Changing Custom Properties
CString GetLanguage ( ) const

Returns the language used in the logic code of the Property Page.

Returns:
"VBScript"
"JScript"
"Python"
See also:
PPGLayout::PutLanguage, cus_ppg_DynamicallyChangingCustomProperties Dynamically Changing Custom Properties
CStatus PutLanguage ( const CString in_strLogicLang)

Sets the language used in the Logic code of the Property Page. When not explicitly set, the default language matches whatever language the associated PluginItem has been implemented in. If the object in question is not based on a Plugin then the default language is VBScript.

Parameters:
in_strLogicLangName of the language to set. Possible values include "VBScript", "JScript" or "Python".

CStatus PutAttribute ( const CString in_UIAttribute,
const CValue in_AttributeValue 
)

Changes the value of an attribute of the PPGLayout.

Parameters:
in_UIAttributeOne of the siPPGLayoutAttribute string constants, specifying which attribute to set.
in_AttributeValueCValue containing a new value for the attribute. It is possible to remove an attribute by providing an empty CValue.
See also:
PPGLayout::GetAttribute, cus_ppg_SettingControlAttributes Setting Control Attributes
CValue GetAttribute ( const CString in_UIAttribute) const

The state of a PPGLayout is made up of two parts:

  • The list of PPGItem objects, which define the controls and their arrangment
  • The set of attributes, which is information that applies to the page as a whole.

This information is exposed via this function. The ::siPPGLayoutAttribute string constants provide a complete list of all these attributes and their meaning.

Some of the most common attributes are also exposed directly as properties of the PPGLayout, for example PPGLayout::GetLogic.

Parameters:
in_UIAttributeOne of the siPPGLayoutAttribute string constants, specifying which attribute to get.
Returns:
Contents of the attribute. This is empty if the attribute is not supported or has not been set.

PPGLayout::PutAttribute, cus_ppg_SettingControlAttributes Setting Control Attributes
PPGItem GetItem ( const CString in_Name) const

Returns an item on the PPGLayout. The requested name is compared with the value returned from PPGItem::GetName until a match is found. It is not defined which item you will get if there are multiple items on the layout with the same requested name.

Parameters:
in_NameName of the item to retrieve
Returns:
The specified PPGItem

cus_ppg_DynamicallyChangingCustomProperties Dynamically Changing Custom Properties
PPGItem GetItem ( LONG  in_Index) const

Returns an item on the PPGLayout based on its index.

Parameters:
in_IndexPosition of the item to retrieve
Returns:
The specified PPGItem
See also:
cus_ppg_DynamicallyChangingCustomProperties Dynamically Changing Custom Properties
LONG GetCount ( ) const

Returns the number of items in the PPGLayout. This count includes all the controls, as well as special items like Groups and Tabs.

Returns:
Total number of items
