problems with a text display in a tab

maveganzones · #1 22-Mar-2005, 12:06

Hi all, im newbie programming with fltk and i have a little problem with the Fl_Text_Display.

I have a Fl_Tabs window with some tabs, no problem.

In one of the tabs i have a Fl_Text_Display that its ok but a little problem. It dosnt draw in the tab, the text display draws itself in the main window. This is the code:

CPP / C++ / C Code:

// the main window
Fl_Window *window = new Fl_Window( 1024,768 );

// the tab window
Fl_Tabs *tabs = new Fl_Tabs(40, 300, 944, 440);
tabs -> box(FL_BORDER_BOX);

// tab one
Fl_Group *tab1 = new Fl_Group(40,330,944,410,"Tab 1");
tab1 -> selection_color(FL_BACKGROUND2_COLOR);
// the text display
Fl_Text_Display *display = new Fl_Text_Display(0,0,900,400);
Fl_Text_Buffer *buffer = new Fl_Text_Buffer();
display -> buffer(buffer);
buffer -> text("Hola");
tab1 -> resizable(display);
tab1 -> end();
Fl_Group::current() -> resizable(tab1);

// tab two
Fl_Group *tab2 = new Fl_Group(40,330,944,410,"Tab 2");
tab2 -> selection_color(FL_BACKGROUND2_COLOR);
tab2 -> end();
Fl_Group::current() -> resizable(tab2);

// tab three
Fl_Group *tab3 = new Fl_Group(40,330,944,410,"Tab 3");
tab3 -> selection_color(FL_BACKGROUND2_COLOR);
tab3 -> end();
Fl_Group::current() -> resizable(tab3);

// ending the tabs
tabs -> add(tab1);
tabs -> add(tab2);
tabs -> add(tab3);
tabs -> value(tab1);
tabs -> end();
tabs -> show();

// ending the main window
window -> end();
window -> show(argc, argv);
return Fl::run();

Thanks

Welcome to GIDForums™. As you see LuciWiz (thanks Lucian) added the code tags to your post. Nice and easy, just surround your post.

Code:


  CPP / C++ / C Code:
  // Your code here

That helps the formatting and highlights the code. `Nuff said.

I compiled your code and it just seems that you are not referring to the screen coords but trying to place relative to a group. You can find some code for this in this thread. I took the liberty to shrink the example down a bit so I could see what I was doing.

CPP / C++ / C Code:

#include <FL/Fl.H>
#include <FL/Fl_Window.H>
#include <FL/Fl_Tabs.H>
#include <FL/Fl_Group.H>
#include <FL/Fl_Text_Display.H>

int main(int argc, char **argv){

  // the main window
  Fl_Window *window = new Fl_Window( 800,600 );

  // the tab window
  Fl_Tabs *tabs = new Fl_Tabs(20, 40, 750, 550);
  tabs -> box(FL_BORDER_BOX);

  // tab one
  Fl_Group *tab1 = new Fl_Group(20,60,700,500,"Tab 1");
  tab1 -> selection_color(FL_BACKGROUND2_COLOR);
  // the text display
  Fl_Text_Display *display = new Fl_Text_Display(25,65,400,400);
  Fl_Text_Buffer *buffer = new Fl_Text_Buffer();
  display -> buffer(buffer);
  buffer -> text("Hola");
  tab1 -> resizable(display);
  tab1 -> end();
  Fl_Group::current() -> resizable(tab1);
  
  // tab two
  Fl_Group *tab2 = new Fl_Group(20,60,700,500,"Tab 2");
  Fl_Text_Display *display2 = new Fl_Text_Display(100,100,200,200);
  display2->buffer(buffer);
  tab2 -> selection_color(FL_BLUE);
  tab2 -> end();
  Fl_Group::current() -> resizable(tab2);
  
  // tab three
  Fl_Group *tab3 = new Fl_Group(20,60,700,500,"Tab 3");
  Fl_Text_Display *display3 = new Fl_Text_Display(200,200,100,100);
  Fl_Text_Buffer *buffer2 = new Fl_Text_Buffer();
  buffer2->text("Hello");
  display3->buffer(buffer2);
  tab3 -> selection_color(FL_RED);
  tab3 -> end();
  Fl_Group::current() -> resizable(tab3);
  
  // ending the tabs
  tabs -> add(tab1);
  tabs -> add(tab2);
  tabs -> add(tab3);
  tabs -> value(tab1);
  tabs -> end();
  tabs -> show();
  
  // ending the main window
  window -> end();
  window -> show(argc, argv);
  return Fl::run();
}

You could have done a redraw on the window when you changed tabs and the overlap would have been repainted. Just a positioning problem.

Hope this is the info you were fishing for.
