Title: WxWidgets C++ - Print out text in a static textbox
Post by: MegAmaNeo on September 19, 2020, 08:41:55 pm
Hello,

I am writing a WxWidget C++ program where I have a button and a static textbox.
My intention is that after clicking the button, a text is printed out in the static box.
Although I am new to C++ and not (yet!) familiar with the concept of pointers, I read that a quick implementation might be to declare the following to lines inside the event function of the button:

wxStaticText *m_statictext;
m_statictext->SetLabel( "test" );

Unfortunately this doesn't work. Do you know if there is a quick implementation?
I pasted you the code below and attached a photo of the properties of the static textbox:

General programming questions are off-topic here, but this is loosely related to wxSmith. You must write something like this:

Code: [Select]
void DeutschprojektFrame::OnButton1Click1(wxCommandEvent& event)
{
   StaticText1->SetLabel( "test" );
}
