create custom fltk dialog / modal window

问题:

I want to create a custom dialog window with fltk. I will put the widgets. Background process should wait to the dialog's finish. I couldn't find any example for this. I am looking fl_input function. I found makeform() function but it didn't help very much.

回答1:

I found innate() function in the library. In the function there is a line following:

while (w->shown()) Fl::wait();

this is my solution. For example:

Fl_Window* w = new Fl_Window(400, 300);
w->set_modal();
w->show();
while (w->shown()) Fl::wait();

will wait the user to close the window.

回答2:

Just use Fl_Window and call set_modal() function.
