Question

I’m trying to create a text control that has the default height but a custom width. This is my current code:

tc = wx.TextCtrl(self, -1)
tc.Size.SetWidth(300)

The width of the text control remains unchanged though. I’ve also tried calling tc.Layout() after changing the width with no results. I don’t want to have to input a custom size in the class constructor since I want it to use the default height. I have also tried being more verbose, in case tc.GetSize returns a deep copy of the Size object:

tc = wx.TextCtrl(self, -1, size=(300, 23))

tc_size = tc.Size
tc_size.SetWidth(300)

tc.Size = tc_size
tc.Layout()

Also to no avail. Why is my code not working, and how do I make it work?

^{Setting the size in the constructor works, so the sizer is irrelevant to the problem.}

Answer 1

I just noticed that I can pass (300, -1) as the size of the text control:

wx.TextCtrl(self, -1, size=(300, -1))

Which results in the text control using the default height. This solves my problem but doesn’t technically answer my question, so I’m holding out for a better answer.
