pymel.core.uitypes.FormLayout

class FormLayout(name=None, orientation='vertical', spacing=2, reversed=False, ratios=None, **kwargs)

class counterpart of mel function formLayout

This command creates a form layout control. A form layout allows absolute and relative positioning of the controls that are its immediate children. Controls have four edges: top, left, bottom and right. There are only two directions that children can be positioned in, right-left and up-down. The attach flags take the direction of an attachment from the argument that names the edge to attach (the second argument). Any or all edges of a child may be attached. There are six ways to attach them: Attach to Form - Attaches an edge to the relevant side of the form layout. Thus -attachForm button3 “left” will attach the left edge of the button to the left edge of the form.Attach to Opposite Side of Form - Attaches an edge relative to the furthest side of the form layout.Attach to Another Control - Attaches an edge to the closest edge of the other control named.Attach to Opposite Side of Another Control - Attaches an edge relative to the furthest side of another control.Attach to Position - Attaches an edge to a position on the form layout. The position is given as a fixed fraction of the -nd/numDivisions value and as this value defaults to 100 it is easiest to think of it as a percentage of the form’s size.Attach to Nothing - Attaches an edge to nothing. The size of the child control will determine this edge’s position.Each edge attachment may have an offset that acts to separate controls visually. There is no default positioning relationship so to have children appear in the form they must have at least one edge attached in each direction. Note:In the flag definitions the arguments follow these rules: controlmust be the name of an immediate child of the form layout.edgemust be one of “top”, “left”, “bottom”, or “right”.positionmay range from 0 to the number of divisions as specified with the -nd/numberOfDivisions flag and gives the fraction of the width of the form as a measurement. This normally means 0-100 so positionmay be thought of as a percentage.offsetis an integer value in pixels.These are multi-use flags so any number of attachments may be made in a single command. Note:Avoid making control attachments that form a loop in control dependencies. For example: window; string $form = formLayout; string $btn1 = button; string $btn2 = button; string $btn3 = button;formLayout -edit-attachControl $btn2 “top” 2 $btn1-attachControl $btn3 “top” 2 $btn2-attachControl $btn1 “right” 2 $btn3 $form;showWindow; $btn2 is attached to $btn1, $btn3 is attached to $btn2, and $btn1 is attached to $btn3. Thus, the placement of $btn1 is dependent on the placement of $btn3, which is dependent on the placement of $btn2, which is dependent on the placement of $btn1. The last control attachment will have created a loop in the dependencies. To prevent runtime errors, Maya will ignore this attachment and instead issue a warning that a cyclical control attachment has been detected in the script. Note:More information on formLayouts can be found in the online User-interface Creation manual.

dragCallback(val=True, **kwargs)

Adds a callback that is called when the middle mouse button is pressed. The MEL version of the callback is of the form: global proc string[] callbackName(string $dragControl, int $x, int $y, int $mods) The proc returns a string array that is transferred to the drop site. By convention the first string in the array describes the user settable message type. Controls that are application defined drag sources may ignore the callback. $mods allows testing for the key modifiers CTL and SHIFT. Possible values are 0 == No modifiers, 1 == SHIFT, 2 == CTL, 3 == CTL + SHIFT. In Python, it is similar, but there are two ways to specify the callback. The recommended way is to pass a Python function object as the argument. In that case, the Python callback should have the form: def callbackName( dragControl, x, y, modifiers ): The values of these arguments are the same as those for the MEL version above. The other way to specify the callback in Python is to specify a string to be executed. In that case, the string will have the values substituted into it via the standard Python format operator. The format values are passed in a dictionary with the keys “dragControl”, “x”, “y”, “modifiers”. The “dragControl” value is a string and the other values are integers (eg the callback string could be “print ‘%(dragControl)s %(x)d %(y)d %(modifiers)d’”)

dropCallback(val=True, **kwargs)

Adds a callback that is called when a drag and drop operation is released above the drop site. The MEL version of the callback is of the form: global proc callbackName(string $dragControl, string $dropControl, string $msgs[], int $x, int $y, int $type) The proc receives a string array that is transferred from the drag source. The first string in the msgs array describes the user defined message type. Controls that are application defined drop sites may ignore the callback. $type can have values of 1 == Move, 2 == Copy, 3 == Link. In Python, it is similar, but there are two ways to specify the callback. The recommended way is to pass a Python function object as the argument. In that case, the Python callback should have the form: def pythonDropTest( dragControl, dropControl, messages, x, y, dragType ): The values of these arguments are the same as those for the MEL version above. The other way to specify the callback in Python is to specify a string to be executed. In that case, the string will have the values substituted into it via the standard Python format operator. The format values are passed in a dictionary with the keys “dragControl”, “dropControl”, “messages”, “x”, “y”, “type”. The “dragControl” value is a string and the other values are integers (eg the callback string could be “print ‘%(dragControl)s %(dropControl)s %(messages)r %(x)d %(y)d %(type)d’”)

getAnnotation(**kwargs)

Annotate the control with an extra string value.

Derived from mel command maya.cmds.formLayout

getBackgroundColor(**kwargs)

The background color of the control. The arguments correspond to the red, green, and blue color components. Each component ranges in value from 0.0 to 1.0.When setting backgroundColor, the background is automatically enabled, unless enableBackground is also specified with a false value.
