wxPython - Panel doesn't cover all frame on show if frame full screen

If I resize the window and I make it full screen again I get the result I desire:

Before

After resize window and full screen

The panel is the one on the far right with a more black grey color. I have the panel and a mainframe where I show the panel inside doing:

def __init_new_trading_bot_panel(self):
    self.__remove_all_panels()
    self.__mNewBotPanel = NewTradingBotPanel(self, wx.DisplaySize())
    self.__mNewBotPanel.Show()

Makes no sense to me, I tried to add an EVT_SHOW on the panel to do a Update after it renderized but it doesn't work too.

Code panel:

from Resources.Constants import Constants, Sizes

On the MainFrame I do:


    def __init__(self):
        wx.Frame.__init__(self, None, wx.ID_ANY, title=Strings.STR_TRADING_BOT, size=Constants.DISPLAY_SIZE_MAIN_FRAME)
        wx.Frame.CenterOnScreen(self)
        self.Maximize(True)
        self.Show()
        self.__init_layout()

    def OnCloseMe(self, event):
        self.Close(True)

    def OnCloseWindow(self, event):
        self.Destroy()

I expect the panel to show full screen on start without resizing the window

If I remove the right panel I get the same with other little panels on vertical until I resize the window and make it again full screen.

BEFORE RESIZE AND FULL SCREEN WITHOUT RIGHT PANEL

(The Light grey should take all the screen in horizontal)

Solution

  • Solved with:

    self.Fit()

    on the Panel init:

    def __init__(self, parent, size):
        wx.Panel.__init__(self, parent, size=size)
        threading.Thread.__init__(self)
        self.__init_layout()


def __init_layout(self):
        [.. Code ..]
        self.Update()
        self.Fit()                 # HERE AFTER UPDATE

    Result on first launch: Result on first launch
