..but if you really want Fl_File_Browser,
this seems to work for selection:
#include <FL/Fl.H>
#include <FL/Fl_Double_Window.H>
#include <FL/Fl_File_Browser.H>
// Demonstrate simple use of Fl_File_Browser with selection -- erco 6/4/11
int main(int argc, char **argv) {
Fl_Double_Window win(300, 400, "File Browser");
Fl_File_Browser fbrow(10,10,300-20,400-20);
fbrow.load(".");
fbrow.type(FL_HOLD_BROWSER); // use for single selection
//fbrow.type(FL_MULTI_BROWSER); // use for multiple selection
win.end();
win.resizable(fbrow);
win.show(argc,argv);
return(Fl::run());
}
To determine what was selected, you can use the usual
Fl_Browser technique of setting a callback(), and using
value() and text(value()) to determine the item.
#include <FL/Fl.H>
#include <FL/Fl_Double_Window.H>
#include <FL/Fl_File_Browser.H>
#include <FL/fl_ask.H>
// Demonstrate Fl_File_Browser with callback -- erco 6/4/11
void BrowserCallback(Fl_Widget *w, void *data) {
Fl_File_Browser *fbrow = (Fl_File_Browser*)w;
int index = fbrow->value();
if ( index > 0 ) {
fl_alert("Selected: %d (%s)\n", index, fbrow->text(index));
} else {
fl_alert("Selected: %d (???)\n", index);
}
}
int main(int argc, char **argv) {
Fl_Double_Window win(300, 400, "File Browser");
Fl_File_Browser fbrow(10,10,300-20,400-20);
fbrow.load(".");
fbrow.type(FL_HOLD_BROWSER);
fbrow.callback(BrowserCallback);
win.end();
win.resizable(fbrow);
win.show(argc,argv);
return(Fl::run());
}
