Undo/redo problem[solved]

[karim24]

hi, i'm having a problem implimenting undo with QUndoStack and QUndoCommand
i created the @QAction *undoAction; @

in the header file,and in the constructer i did this
@undoAction = undoStack->createUndoAction(this, tr("&Undo"));@

then push a command into the stack "i know that the command got pushed because i saw it with the debuger"

but when i run the program and press undo the function that i implimented in the command::undo() doesn't get excuted
but when i call
@undoStack->undo();@

using an other button the function that i implimented in the command::undo() excutes

i hope my question makes sens ,and i will provide any other details

Hi,

Can you post your Qt/OS versions ?

[karim24]

ok,sorry that i bothered you
but i solved the problem,the problem was that, in the constructer i allocated the undoStack two times
@ undoStack = new QUndoStack(this);@

then
@ undoStack = new QUndoStack(this);@

i deleted one and now runs fine
