How can I get the width of a string in Python?

[heiner55]

You should have experience with GUI programming or 2D-programming.
If not, it is difficult.

#!/usr/bin/python3
import wx  # wxpython 4.x
app = wx.App()

window = wx.Frame(None, title = "wxPython Frame", size = (300,200))
panel  = wx.Panel(window)

txt   = "Hello World"
label = wx.StaticText(panel, label = txt, pos = (100,50))

dc   = wx.ScreenDC()
dc.SetFont(label.GetFont())
size = dc.GetTextExtent(txt)
txtwh = "width=%d  height=%d" % (size.width, size.height)
label = wx.StaticText(panel, label = txtwh, pos = (100,100))

window.Show(True)
app.MainLoop()
