Selection behavior for Fl_Check_Browser?

[Tony]

Hi all,

Reading the docs for Fl_Check_Browser, it states that "The Fl_Check_Browser widget displays a scrolling list of text lines that may be selected and/or checked by the user." However, I see no mechanism to select (not check) lines in the browser: it looks like selection is determined by cb_item->selected, but nothing ever sets this to 1.

How can I get line selection behavior in Fl_Check_Browser?

Thanks,

Tony

I don't think you can select an item in the check browser in the classical sense. Fl_Check_Browser::value will return the last item that was clicked IIRC. Apart from that, the check button is the significant piece here.

Thanks for your reply! That's unfortunate :(

Is there a way to have a widget that does combine these two behaviors together?

(Top posting, sorry. I'm on my phone...)

If set_checked() isn't what you want (and it sounds like it is not!) then I guess I always assumed the stock behaviour of the base widget would do that - but since you're asking I'm guessing it does not.

Erco has a neat demo of making a widget browser on his Cheat Sheet; it would be feasible to tweak that to hold lines of text with check boxes then add selection handling to suit your needs, I reckon.

Other than that... I got nothing...

As Ian says, you can still use item_select() and item_selected() form the super class.

Thanks for the pointer, I'll take a look!

    I just woke up, so maybe I'm not seeing this correctly, but maybe to select items
    you just want to use one of the other Fl_Xxx_Browser classes instead:

        Fl_Hold_Browser
        Fl_Select_Browser
        Fl_Multi_Browser

    Fl_Multi_Browser is the one I use most often.

    You can test all the variations by running the test/browser demo, and changing the
    little pulldown at the lower right that says 'Multi' on startup. It can be changed to
    the different browser types.
