Hi, all -
I am trying to create a little widget/group made of an Fl_Input (or text
editor) and a drop-down-menu-like suggestions box. The end goal is to make
something similar to an AJAX-y suggestions box found on google, or the firefox
sites suggestions, etc.
It's easy for me to create/fill/show a popup made of an Fl_Select_Browser
inside an Fl_Menu_Window. If I use an Fl_Menu_Window, though, show() steals
focus and the mouse cursor from my Fl_Input widget. I can't send back focus
because the menu is a new window ... or at least I haven't figured out how to
send it back ... ?
In short, I have something like the pseudo-code below. I'm happy to post my
full test/draft if that helps.
Maybe someone else has been through this before?
Denton
// a 'drop down or popup' box with suggested text completions
class SuggestionsBox : public Fl_Menu_Window {
Fl_Select_Browser *browser_; // ideally ...
int handle(int event) {
}
class SuggestionsInput : public Fl_Input {
..
Fl_Input *input_;
... etc etc ...
browser_cb_() {
// when user clicks a browser item, add to input_
// then, hide browser_
}
int handle(int event) {
// on keypress, take input_->value() as prefix.
// search db/tree of terms, put those into browser_.
// show browser_.
}
public:
InputWithSuggestionsBox(..) {
// always display input_
Fl_Group::end();
win_ = new Fl_Menu_Window(...)
browser_ = new Fl_Select_Browser(...)
browser_->callback(browser_cb_, this)
win_->end();
... etc
}
// etc etc
};
