Setting Font Size in wxTextCtrl Topic is solved

[purplex88]

I am trying to zoom in wxTextCtrl by changing only font size:

Code: Select all

case '+':
{
	if (event.ControlDown())
	{
		wxTextAttr attr;
		int PointSize = m_textCtrl->GetFont().GetPointSize();
		attr.SetFontPointSize(PointSize + 1);
		m_textCtrl->SetStyle(-1, -1, attr);
	}
	else
		event.Skip();

	break;
}
case '-':
{
	if (event.ControlDown())
	{
		// ....
	}
	else
		event.Skip();

	break;
}

It doesn't work the second time I press Ctrl+. I am looking for the correct way to handle this.

Code: Select all

int PointSize = m_textCtrl->GetFont().GetPointSize();

I would guess that this line always returns the same value. Setting an attribute does not change the default font size of the control.

Yes, this is true.I also tried using SetDefaultStyle() but nothing changes.

Do one of these:
a) set a bigger font with m_textCtrl->SetFont(...)
b) get the current style with m_textCtrl->GetStyle(...)
c) store the current point size somewhere.

Oh, yes I was about to say that I found the solution.

I used GetFont and SetFont like this:

Code: Select all

wxFont font = m_textCtrl->GetFont();
font.SetPointSize(font.GetPointSize() + 1);
m_textCtrl->SetFont(font);

However, It appears that Ctrl + key combination is already reserved for something and it doesn't trigger an event I want to handle.

Edit: Never mind, I am now using WXK_NUMPAD_ADD.
