wxColour - Recording RGB Topic is solved

[TransButtah]

For my program, when the user changes the color using a color dialog, I would like the program to send the Red, Green, and Blue values to a file so they can be loaded next time the program starts up. I have been trying to use wxColour::Red(), wxColour::Blue(), and wxColour::Green(), like this:

Code: Select all

wxColour Color1(0,0,75);
wxTextFile file1;
file1.Open(wxT("Colors.txt"));
file1[0] = Color1.Red();
file1[1] = Color1.Green();
file1[2] = Color1.Blue();
file1.Close();

This doesn't seem to work, though. Anybody know what's wrong? I know how to make it load the colors on startup, but I just can't figure this part out.

Thanks!

you always have to call wxTextFile::Write() to submit the changes you've made:

Thanks! Stupid me. It works perfectly now, the colors can be reloaded and loaded whenever needed.

Thanks!

Just a little tip:

to make the conversion Colour <-> string easier, there are the functions

wxString GetAsString(long flags) const

and

bool Set(const wxString & str)

to get and set colours from one String
