I've used Fl_Box for status bars, eg:
statusbar = new Fl_Box(0,H-20,W,20);
statusbar->box(FL_FLAT_BOX); // make the box 'flat' (no
decorations)
statusbar->align(FL_ALIGN_LEFT|FL_ALIGN_INSIDE);// align status text to
left/top of widget
statusbar->color(48-2); // slightly darker than default
FLTK widget color (48)
..where W,H are the width/height of your window, and '20' is
about how "thick" you probably want the status bar to be to show
a single line of text. (Use a larger number to support more lines of
text)
Then you can just call the following to change the message:
statusbar->copy_label(msg);
statusbar->redraw();
If you put that into a function called e.g. 'StatusMessage()',
then you can just call that with a string to change the status message,
e.g.
void StatusMessage(const char *msg) {
statusbar->copy_label(msg);
statusbar->redraw();
}
Both Fl_Box and Fl_Group will act similarly; you can probably
interchange
them without any different effect.
If you want multiline, you can just make the status bar 'thicker';
I believe the label() method will handle crlf's normally, eg:
StatusMessage("This is line one\n"
"This is line two");
..which would show both lines of text, assuming the bar is thick enough.
Usually status bars don't need to be copy/paste-able, but if it did,
use Fl_Output, as it supports mouse highlighting and keyboard nav
selection
IIRC.
Here's a small test program:
---- snip
#include <FL/Fl.H>
#include <FL/Fl_Window.H>
#include <FL/Fl_Box.H>
#define W 600
#define H 300
Fl_Box *G_statusbar = 0; // global!
void StatusMessage(const char *msg) {
G_statusbar->copy_label(msg);
G_statusbar->redraw();
}
int main() {
Fl_Window win(W,H,"Test1");
G_statusbar = new Fl_Box(0,H-35,W,35);
G_statusbar->box(FL_FLAT_BOX); // make the box 'flat'
(no decorations)
G_statusbar->align(FL_ALIGN_LEFT|FL_ALIGN_INSIDE); // align status text to
left/top of widget
G_statusbar->color(48-2); // slightly darker than
default FLTK widget color (48)
win.show();
StatusMessage("Started: OK"); // single line of
status text
//StatusMessage("Started: OK\nInitialized: OK"); // two lines of status
text should work too
return (Fl::run());
}
---- snip
