Detailed Description

Warning

QDesignerFormWindowCursorInterface is a convenience class that provides an interface to the associated form window’s text cursor; it provides a collection of functions that enables you to query a given form window’s selection and change the selection’s focus according to defined modes ( MoveMode ) and movements ( MoveOperation ). You can also use the interface to query the form’s widgets and change their properties.

The interface is not intended to be instantiated directly, but to provide access to the selections and widgets of Qt Widgets Designer’s current form windows. QDesignerFormWindowInterface always provides an associated cursor interface. The form window for a given widget can be retrieved using the static findFormWindow() functions. For example:

formWindow = QDesignerFormWindowInterface.findFormWindow(myWidget)
formWindow.cursor().setProperty(myWidget, myProperty, newValue)

You can retrieve any of Qt Widgets Designer’s current form windows through Qt Widgets Designer’s form window manager .

Once you have a form window’s cursor interface, you can check if the form window has a selection at all using the hasSelection() function. You can query the form window for its total widgetCount() and selectedWidgetCount() . You can retrieve the currently selected widget (or widgets) using the current() or selectedWidget() functions.

You can retrieve any of the form window’s widgets using the widget() function, and check if a widget is selected using the isWidgetSelected() function. You can use the setProperty() function to set the selected widget’s properties, and the setWidgetProperty() or resetWidgetProperty() functions to modify the properties of any given widget.

Finally, you can change the selection by changing the text cursor’s position() using the setPosition() and movePosition() functions.

class MoveOperation

This enum describes the types of text cursor operation that can occur in a form window.

Constant

Description

QDesignerFormWindowCursorInterface.NoMove

QDesignerFormWindowCursorInterface.End

Moves the cursor to the end of the focus chain.

QDesignerFormWindowCursorInterface.Next

Moves the cursor to the next widget in the focus chain.

QDesignerFormWindowCursorInterface.Prev

Moves the cursor to the previous widget in the focus chain.

QDesignerFormWindowCursorInterface.Left

The cursor moves to the left.

QDesignerFormWindowCursorInterface.Right

The cursor moves to the right.

QDesignerFormWindowCursorInterface.Up

The cursor moves upwards.

QDesignerFormWindowCursorInterface.Down

The cursor moves downwards.
class MoveMode

This enum describes the different modes that are used when the text cursor moves.

Constant

Description
