如何使wxFrame行为像一个模态wxDialog对象 [英] How to make a wxFrame behave like a modal wxDialog object

问题描述

有可能使wxFrame对象的行为像一个模态对话框，因为创建wxFrame对象的窗口停止执行，直到wxFrame对象退出？

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?

在小型游戏上工作，遇到以下问题。我有一个主程序窗口主持主要应用程序（战略部分）。偶尔，我需要将控制转移到第二个窗口，以解决部分游戏（战术部分）。在第二个窗口中，我希望第一个窗口中的处理停止，等待完成第二个窗口中的工作。

I'm working on a small game and have run into the following problem. I have a main program window that hosts the main application (strategic portion). Occasionally, I need to transfer control to a second window for resolution of part of the game (tactical portion). While in the second window, I want the processing in the first window to stop and wait for completion of the work being done in the second window.

通常模态对话框做的技巧，但我想要的新窗口有一些功能，我似乎无法得到一个wxDialog，即在底部的状态栏和能够调整/最大化/最小化窗口（这应该是可能的，但不工作，请参阅此问题如何获取最小化和最大化按钮出现在wxDialog对象上）。

Normally a modal dialog would do the trick but I want the new window to have some functionality that I can't seem to get with a wxDialog, namely a status bar at the bottom and the ability to resize/maximize/minimize the window (this should be possible but doesn't work, see this question How to get the minimize and maximize buttons to appear on a wxDialog object).

作为补充说明，我想要第二个窗口的功能需要保持完全从主窗口解耦，因为它将被分离到一个单独的程序最终。

As an addition note, I want the second window's functionality needs to stay completely decoupled from the primary window as it will be spun off into a separate program eventually.

有人做过这个或有任何建议吗？

Has anyone done this or have any suggestions?

从类似的解决方案，并提出了这个解决方案，创建一个框架，通过执行frame.MakeModal（）禁用其他窗口，并显示框架后，停止执行开始和事件循环，当框架关闭退出事件循环例如我这里是使用wxpython的示例，但它应该类似于wxwidgets。

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()
