Wx.html2, Unable to lower screen priority

well, once you know what you want (I don’t really) it should be achievable (at least in wxPython) :joy:

import wx
import wx.html2

class WebBrowser(wx.Frame):
    def __init__(self, parent):
        super().__init__(parent)
        self.wv = wx.html2.WebView.New(self)

        self.max = False

        self.SetSize(width, self.GetSize()[1])

    def set_max(self, gui):
        if self.max:
            self.SetPosition(self.position)
            if self.size[1] < 40:
                self.size[1] = int(gui.GetSize()[1] + 40)
            elif not gui.GetSize()[1] < self.size[1] - 20:

            self.SetSize(self.size)
