multiple windows under wx

Scripting Issues
1

Dear Forum,

i’m trying to set up an App with 3 splitter windows containing perspective,top,and front view and there are some issues. I hope you can point me in the right direction to resolve them (code based on snipplets found in the forum)

import wx

from direct.showbase.ShowBase import ShowBase
from direct.wxwidgets.ViewPort import Viewport
from direct.wxwidgets.WxPandaWindow import WxPandaWindow
import panda3d.core as core

core.loadPrcFileData('startup', 'window-type none')

class Frame(wx.Frame):
    def __init__(self, *args, **kwargs):
        wx.Frame.__init__(self, *args, **kwargs)
        
        self.Bind(wx.EVT_SIZE, self.onSize)
        
        self.split1 = wx.SplitterWindow(self)
        self.split2 = wx.SplitterWindow(self.split1)           
        
        self.p0 = wx.Panel (self.split1)
        self.p1 = wx.Panel (self.split2)
        self.p2 = wx.Panel (self.split2)

        self.p0.SetBackgroundColour((200,25,50))
        self.p1.SetBackgroundColour((25,200,50))
        self.p2.SetBackgroundColour((25,25,200))
        
        self.split2.SetMinimumPaneSize(10)
        self.split2.SplitHorizontally(self.p1,self.p2,400) 
        self.split1.SetMinimumPaneSize(10)
        self.split1.SplitVertically(self.p0,self.split2,300)  

        self.split1.SetPosition((0,0))
        self.split1.SetSize((800,600))
        self.split2.SetSashPosition(300)       

        self.panda =  WxPandaWindow(parent = self.p0)
        self.panda1 = WxPandaWindow(parent = self.p1)       
        self.panda2 = WxPandaWindow(parent = self.p2)
        
        self.onSize(1)
   
    def onQuit(self, evt):
        self.Close()
        
    def onSize(self, evt):
        self.split1.SetSize((self.GetSize().width,self.GetSize().height))
        self.p0.SetSize((-1,-1))
        self.p1.SetSize((-1,-1))
        self.p2.SetSize((-1,-1))

class App(ShowBase):
    def __init__(self):
        ShowBase.__init__(self, fStartDirect=False, windowType=None)       
        # setup application window       
        self.startWx()
        self.wxApp.Bind(wx.EVT_CLOSE, self.quit)
        self.frame = Frame(None, wx.ID_ANY, 'Editor', size=(800, 600))

        wp = core.WindowProperties()
        wp.setOrigin(0,0)
        wp.setSize(400,300)
        wp.setParentWindow(self.frame.panda.GetHandle())
        base.openMainWindow(type = 'onscreen', props=wp)
        base.setBackgroundColor(0,1,0,1)
        
        wp1 = core.WindowProperties()
        wp1.setOrigin(0,0)
        wp1.setSize(400,300)
        wp1.setParentWindow(self.frame.panda1.GetHandle())
        base.openWindow(type = 'onscreen', props=wp1)
        base.setBackgroundColor(1,1,0,1)
        
        wp2 = core.WindowProperties()
        wp2.setOrigin(0,0)
        wp2.setSize(400,300)
        wp2.setParentWindow(self.frame.panda2.GetHandle())
        base.openWindow(type = 'onscreen', props=wp2)
        base.setBackgroundColor(1,1,1,1)        

        self.frame.Show()
       
        # setup mouse/picking/selection system

        def foo():
            print "debug"
        self.accept("mouse1", foo)
        self.accept("mouse3", foo)
        self.accept("t", foo)

    def quit(self, event=None):
        self.onDestroy(event)
        try:
            base
        except NameError:
            sys.exit()
        base.userExit()

app = App()
app.run()

Why do the WxPandawindows not size to 400,300 ?
Why is only the 1st window affected by the colour change ?
how do I get the other windows to accept mouse/keyboard input?

with best wishes

Ok, wxpandawindow as child of splitterwindow with size of parent window seems to be doing the sizing problem.

The colour and mouse thing are still open…

but there is still something wrong. The first Window is rendered correct and in the other windows a correct render apears for a short moment and then a white stenciled aerea apears.
