Opening a new dialog when clicking accept

[mathia]

Hi,

I have task that requires the user to make multiple choices. The first dialog (in the task menu) pops up and gives the user a drop down menu, the user clicks accept, and then the user should be taken to the next dialog. A minimal example would be:

Code: Select all

class PanelA:
    def accept(self):
        pb = PanelB()
        FreeCADGui.Control.closeDialog()
        FreeCADGui.Control.showDialog(pb)


class PanelB:
    def accept(self):
        FreeCADGui.Control.closeDialog()

then calling

Code: Select all

Gui.Control.showDialog(PanelA())

and clicking accept. This used to work in FreeCAD 0.16 and would show me panel b, but after this fix: https://github.com/FreeCAD/FreeCAD/comm ... ef62caf236 to postpone deletion of the dialog, this is no longer possible.

Does anyone have any suggestions for how I can get this behavior again?

The trick is to also delay the execution of the 2nd task panel.

Code: Select all

from PySide import QtCore

class PanelA:
    def accept(self):
        FreeCADGui.Control.closeDialog()
        QtCore.QTimer.singleShot(0, lambda: FreeCADGui.Control.showDialog(PanelB()))


class PanelB:
    def accept(self):
        FreeCADGui.Control.closeDialog()


Gui.Control.showDialog(PanelA())

That worked perfectly!
Thanks! I've never seen that function before.
