I tried to display custom text on top of an image. My first attempt was to use
InvisibleBox as below:
int main(int argc, char ** argv) {
fltk::register_images();
fltk::Window * window = new fltk::Window(0, 0, 480, 640, "Test");
window->begin();
window->image(new fltk::TiledImage(fltk::SharedImage::get("test.png")));
fltk::InvisibleBox * b = new fltk::InvisibleBox(60, 120, 340, 80,
"Sample text.");
b->labelfont(fltk::COURIER_BOLD);
b->labelsize(28);
window->end();
window->show(argc, argv);
return fltk::run();
}
but in this example even "Sample text." is not visible. I can't find any
predefined box type, that allows to display text on top of other widget (image
on my example) with no background and no border.
I created custom class by some mindless copy-paste from src/UpBox.cxx:
struct BoxNoBackground : public fltk::Box {
void _draw(const fltk::Rectangle & r) const {}
BoxNoBackground() : fltk::Box("xyz") { set_inset(1); }
};
static BoxNoBackground bnb;
static fltk::Box * const BOX_NO_BACKGROUND = &bnb;
and further use:
b->box(BOX_NO_BACKGROUND);
but it would be strange if there isn't solution without creating custom class.
What is the preferred way to display text on top of other widget?
