I was reading section 8.9 Event Propagation , and I encountered some methods in that sections said to be controlling the leaf widgets.
⢠Fl::add_handler() ⢠Fl::belowmouse() ⢠Fl::focus() ⢠Fl::grab() ⢠Fl::modal() ⢠Fl::pushed() ⢠Fl::release()(deprecated, see Fl::grab(0)) ⢠Fl_Widget::take_focus() I just want to what they're all about , why we needed these function , It'd be awesome if you could please explain by example only one of those important methods. Another question : I'm using Fl_Text_Display widget which has to have buffer of type Fl_Text_Buffer , Which I initialize with sufficient buffer size. Now to update the text of buffer I'm using it's Fl_Text_Buffer::insert() method. is it OK to do that? , is this the idiom to update the buffer (exclude append here please)? Last question : "Fl::event_button() Fl::event_clicks() Fl::event_dx()" , these method are any useful at all? , since suppose my event handler gets called for some event click etc , then I already know which event caused my handler to invoke (supposing my function currently handles only one event at the time) , then why should I use this call Fl::event_clicks(); at all?. I really appreciate any help, efforts and others time given for my questions. Thanks :)
