Fl_Input not updating when typing

[Tobi Pérusse]

Hi guys

I'm trying to add a Fl_Input in a group in a tab but I can't get it to display the text as I type. When the window lost then get focus again it display its value. I have no clue how to fix that
. Any idea?

Hmm, not seeing anything immediate... Can you make a small example
that is compilable so we can test this, please.
The samples you posted are useful but not complete enough to test.

I assume the samples in the fltk test folder work OK on your machine?

Here it is. This is a test project for learning. It's using 1.3.5 from fedora 32 repository. I have not test the git repo yet.

Sorry, there is much too much code there for me to look at, and I will
not touch the binary elements. I suspect others here will also find
this tarball too much to process...

If you want help, please post a *small*, complete, compilable example,
preferably as a single file, that exhibits the specific problem being
discussed.

Sorry about that, will make a smaller one.

I found the problem.

In PropertiesEditorWindow::addTabs(), you create your tab widget as follows:

    Fl_Tabs *tabs = new Fl_Tabs(5, 0, 530, 30);

Change it to:

    Fl_Tabs *tabs = new Fl_Tabs(5, 0, 530, 300);

And all will be well.

[The window is 330 pixels high; the interior group is 250 pixels high; the small tab height is blocking redraw of any contained widgets.]

Here is the simplified code which shows the problem [assumed to be invoked as a callback from e.g. a button]:

void preferences(Fl_Widget*, void*)

{

    Fl_Window* win = new Fl_Window(540, 330);

    win->copy_label("Title");

    Fl_Tabs* tabs = new Fl_Tabs(5, 0, 530, 30); // change '30' to '300' to fix

    Fl_Group* general = new Fl_Group(5, 30, 530, 250, "Blah");

    Fl_Input* usernameInput = new Fl_Input(180, 40, 350, 30, "Username:");

    general->end();

    tabs->end();

    win->end();

    win->show();

    while (win->shown()) {

        Fl::wait();

    }

}

I confirm it work! The tabs doesn't work as I was expecting. I was thinking the size should include the tabs only, similar to the menu bar.

Thanks a lot guys! And thanks for this group :)

Good catch K.

I actually did take a squint at the sample code (despite saying I wouldn't) looking for exactly that sort of error, as I was assuming it was a widget area / visibility thing.

And I totally missed that... I can only imagine I saw the 30 as 300 and thought it was OK!

Cheers,
