I need the GENERAL CASE which is to to set a (possibly) different foreground
AND BACKGROUND color for each char. Consider the following.
#include <FL/Fl.H>
#include <FL/Fl_Window.H>
#include <FL/Fl_Text_Display.H>
Fl_Text_Display::Style_Table_Entry stable[] = {
{ FL_RED, FL_COURIER, 18 }, // A - Red
{ FL_BLUE, FL_COURIER, 18 }, // B - Blue
{ FL_MAGENTA, FL_COURIER, 18 }, // C - Magenta
};
int main() { // Fl_Text_Display example with color styles . -erco
int w = 640; int h = 480;
Fl_Window *win = new Fl_Window(w, h, "Display");
Fl_Text_Display *disp = new Fl_Text_Display(10,10,w-20,h-20);
Fl_Text_Buffer *tbuff = new Fl_Text_Buffer();
Fl_Text_Buffer *sbuff = new Fl_Text_Buffer();
disp->buffer(tbuff);
int stable_size = sizeof(stable)/sizeof(stable[0]);
disp->highlight_data(sbuff, stable, stable_size, 'A', 0, 0);
tbuff->text("red line 1\nblu line 2\nmag line 3\n");
tbuff->replace(2,7,"VWXYZ");
sbuff->text("AAAAAAAAAA\nBBBBBBBBBB\nCCCCCCCCCC\n");
sbuff->replace(2,7,"BACCD");
win->resizable(*disp); win->show();
return(Fl::run());
}
By using repeated replaces the entire display's colours can be
controlled BUT NOT THE BACKGROUND. Why can't each Style_Table_Entry
contain background color information somehow?
