Detailed Description

See also:

Custom Controls. Class ToolItem, Class MacroButtonData, Class CUIFrameMsgHandler, Class ICustStatusEdit, Class ICustStatus, Class ICustButton.

Description:

This control allows the creation of toolbars containing buttons (push, check, and fly-offs), status fields, separators (spacers), and other Windows or user defined controls.

\ The standard size for 3ds Max toolbar button icons is 16x15 or 16x16 pixels.

In 3ds Max 3.0 and later toolbars may have multiple rows, or appear vertically. They may also have macro buttons (added with the MacroButtonData class) which may have icons or text.

To initialize the pointer to the control call:
ICustToolbar *GetICustToolbar(HWND hCtrl);
To release the control call:
ReleaseICustToolbar(ICustToolbar *ict);
The value to use in the Class field of the Custom Control Properties dialog is: CustToolbar

Note: The TB_RIGHTCLICK message is sent when the user right clicks in open space on a toolbar:
Also Note: To add tooltips to the toolbar controls you can do so by capturing the WM_NOTIFY message in the dialog proc. For complete sample code see /MAXSDK/SAMPLES/HOWTO/CUSTCTRL/CUSTCTRL.CPP. The specific message is processed as shown below.

case WM_NOTIFY:
 // This is where we provide the tooltip text for the
 // toolbar buttons...
 if(((LPNMHDR)lParam)->code == TTN_NEEDTEXT) {
   LPTOOLTIPTEXT lpttt;
   lpttt = (LPTOOLTIPTEXT)lParam;
   switch (lpttt->hdr.idFrom) {
     case ID_TB_1:
       lpttt->lpszText = _M("Do Nothing Up");
       break;
     case ID_TB_2:
       lpttt->lpszText = _M("Do Nothing Down");
       break;
     case ID_TB_3:
       lpttt->lpszText = _M("Do Nothing Lock");
       break;
     case IDC_BUTTON1:
       if (to->custCtrlButtonC->IsChecked())
         lpttt->lpszText = _M("Button Checked");
       else
         lpttt->lpszText = _M("Button Un-Checked");
       break;
     };
   }
 break;

Member Function Documentation

virtual void SetImage

(

HIMAGELIST

hImage

)

[pure virtual]

Search for all occurrences

Remarks:

This method establishes the image list used to display images in the toolbar.

Parameters:

HIMAGELIST hImage

The image list. An image list is a collection of same-sized images, each of which can be referred to by an index. Image lists are used to efficiently manage large sets of icons or bitmaps in Windows. All images in an image list are contained in a single, wide bitmap in screen device format. An image list may also include a monochrome bitmap that contains masks used to draw images transparently (icon style). The Windows API provides image list functions, which enable you to draw images, create and destroy image lists, add and remove images, replace images, and merge images.

virtual void AddTool	(	ToolItem &	entry,
		int	pos = -1
	)		[pure virtual]

Search for all occurrences

Remarks:

The developer calls this method once for each item in the toolbar. The items appear in the toolbar from left to right in the order that they were added using this method. (Note that this method adds tools to the custom toolbar and not the 3ds Max toolbar).

Parameters:

const ToolItem& entry

Describes the item to add to the toolbar.

int pos=-1

Controls where the added tool is inserted. The default of -1 indicates the control will be added at the right end of the toolbar.

virtual void AddTool2	(	ToolItem &	entry,
		int	pos = -1
	)		[pure virtual]

Search for all occurrences

Remarks:

Currently this method is identical to the AddTool() method.

Parameters:

ToolItem& entry

Describes the item to add to the toolbar.

int pos=-1

Controls where the added tool is inserted. The default of -1 indicates the control will be added at the right end of the toolbar.

virtual void DeleteTools	(	int	start,
		int	num = -1
	)		[pure virtual]

Search for all occurrences

Remarks:

This method is used to delete tools from the toolbar.

Parameters:

int start

Specifies which tool is the first to be deleted.

int num=-1

Specifies the number of tools to delete. If this parameter is -1 (the default) it deletes 'start' through count-1 tools.

virtual void SetBottomBorder
