The Edit Menu

Undo

Undoes the last action. Text next to the word Undo indicates what this action was. You can undo an unlimited number of steps.

Redo

Redoes the last action. This menu item is only available if you just undid one or more actions.

Cut

Removes the currently selected GUI element (or elements) from its form and puts it into the clipboard. You can then paste it back into the same or another form with the Paste menu item. You can also paste the clipboard contents into any text editor to get an XML-like description of the GUI element, even though this will rarely be useful.

This menu item is not available if no GUI element is currently selected.

Copy

Copies the currently selected GUI element (or elements) from its form into the clipboard. You can then paste it into the same or another form with the Paste menu item. You can also paste the clipboard contents into any text editor to get an XML-like description of the GUI element, even though this will rarely be useful.

This menu item is not available if no GUI element is currently selected.

Paste

Pastes the GUI element (or elements) that is currently in the clipboard into the currently active form. The position is the position the GUI element had before it was copied (relative to its form at that time) plus a little offset so that you can paste a GUI element multiple times without the individual copies completely covering each other.

This menu item is only available if the clipboard contains a GUI element that was copied there from Qt Designer.

Delete

Removes the currently selected GUI element (or elements) from its form without putting it into the clipboard.

Select All

Selects all GUI elements in the currently active form.

Check Accelerators

Checks whether the accelerators in the currently active form are consistent; i.e., that no accelerator is used twice.

Slots

Opens the dialog that lets you edit the slots for the currently active form and add new slots.

Connections

Opens the dialog that shows you the connections between signals and slots on the currently active form and lets you edit them.

Form Settings

Opens a dialog that lets you make certain settings that apply only to the currently active form.

Preferences

Opens a dialog that lets you make settings that apply to Qt Designer as a whole.
