public class QUndoView
extends QListView

The QUndoView class displays the contents of a QUndoStack. QUndoView is a QListView which displays the list of commands pushed on an undo stack. The most recently executed command is always selected. Selecting a different command results in a call to QUndoStack::setIndex(), rolling the state of the document backwards or forward to the new command.

The stack can be set explicitly with setStack(). Alternatively, a QUndoGroup object can be set with setGroup(). The view will then update itself automatically whenever the active stack of the group changes.

Method Detail

cleanIcon

public final QIcon cleanIcon()
This property holds the icon used to represent the clean state. A stack may have a clean state set with QUndoStack::setClean(). This is usually the state of the document at the point it was saved. QUndoView can display an icon in the list of commands to show the clean state. If this property is a null icon, no icon is shown. The default value is the null icon.


emptyLabel

public final java.lang.String emptyLabel()
This property holds the label used for the empty state. The empty label is the topmost element in the list of commands, which represents the state of the document before any commands were pushed on the stack. The default is the string "<empty>".


group

public final QUndoGroup group()
Returns the group displayed by this view.

If the view is not looking at group, this function returns 0.

See also:
setGroup(), and setStack().


setCleanIcon

public final void setCleanIcon(QIcon icon)
This property holds the icon used to represent the clean state. A stack may have a clean state set with QUndoStack::setClean(). This is usually the state of the document at the point it was saved. QUndoView can display an icon in the list of commands to show the clean state. If this property is a null icon, no icon is shown. The default value is the null icon.


setEmptyLabel

public final void setEmptyLabel(java.lang.String label)
This property holds the label used for the empty state. The empty label is the topmost element in the list of commands, which represents the state of the document before any commands were pushed on the stack. The default is the string "<empty>".


setGroup

public final void setGroup(QUndoGroup group)
Sets the group displayed by this view to group. If group is 0, the view will be empty.

The view will update itself autmiatically whenever the active stack of the group changes.

See also:
group(), and setStack().


setStack

public final void setStack(QUndoStack stack)
Sets the stack displayed by this view to stack. If stack is 0, the view will be empty.

If the view was previously looking at a QUndoGroup, the group is set to 0.

See also:
stack(), and setGroup().


stack

public final QUndoStack stack()
Returns the stack currently displayed by this view. If the view is looking at a QUndoGroup, this the group's active stack.

setStack(), and setGroup().
