How to make a wxFrame behave like a modal wxDialog object

Question

Is is possible to make a wxFrame object behave like a modal dialog box in that the window creating the wxFrame object stops execution until the wxFrame object exits?

Answer 1

I was also looking from similar solution and have comeup with this solution, create a frame, disable other windows by doing frame.MakeModal() and to stop execution start and event loop after showing frame, and when frame is closed exit the event loop e.g. I here is sample using wxpython but it should be similar in wxwidgets.

import wx

class ModalFrame(wx.Frame):
    def __init__(self, parent, title):
        wx.Frame.__init__(self, parent, title=title, style=wx.DEFAULT_FRAME_STYLE|wx.STAY_ON_TOP)

        btn = wx.Button(self, label="Close me")
        btn.Bind(wx.EVT_BUTTON, self.onClose)
        self.Bind(wx.EVT_CLOSE, self.onClose) # (Allows main window close to work)

    def onClose(self, event):
        self.MakeModal(False) # (Re-enables parent window)
        self.eventLoop.Exit()
        self.Destroy() # (Closes window without recursion errors)

    def ShowModal(self):
        self.MakeModal(True) # (Explicit call to MakeModal)
        self.Show()

        # now to stop execution start a event loop 
        self.eventLoop = wx.EventLoop()
        self.eventLoop.Run()


app = wx.PySimpleApp()
frame = wx.Frame(None, title="Test Modal Frame")
btn = wx.Button(frame, label="Open modal frame")

def onclick(event):
    modalFrame = ModalFrame(frame, "Modal Frame")
    modalFrame.ShowModal()
    print "i will get printed after modal close"

btn.Bind(wx.EVT_BUTTON, onclick)

frame.Show()
app.SetTopWindow(frame)
app.MainLoop()
