Finding right width of TextCtrl

wxPython Users

Hello All,

How can I find the right width for a TextCtrl for a givn string.

I've tried:
    # ...
    do = wx.TextDataObject(txt)
    t = wx.TextCtrl(self, -1, txt, size=((do.GetTextLength(), -1))
    sizer.Add(t, 0, wx.EXPAND)
    # ...

but it doesn't seem to work.

Bye.

You're finding the width of the string in characters, but the TextCtrl wants
the width of the string in pixels, if I'm not mistaken.

Hello,
I tried this out, maybe the values are not exact.

(I measured out with a screenshot (only the filled area)
width: 21 (rather accurate)
height: 9

t = wx.TextCtrl(shell, -1, "hallo")

t.GetTextExtent("hallo") delivers:
(22, 13)

You must make a temporary screen DC, then use dc.GetTextExtent()
     dc=wx.ScreenDC()
     #if you have a font ...
     dc.SetFont(font)
     (w,h)=dc.GetTextExtent(txt)

[Franz]

t = wx.TextCtrl(shell, -1, "hallo")

t.GetTextExtent("hallo") delivers:
(22, 13)

That worked.

Thanks,
