How to get the text of an item selected, using ComboBox??

ComboBox inherits from Label class, and the text is gotten via ComboBox::getCaption. Could you please invest some effort before asking these questions? Intellisense is your friend.

No! I have looked up into intellisense always.. but i'm doing with the wrong way..
I'm doing this:
mComboServerList->getDropDownList()->getListItem(0)->getCaption()
Now it's ok... Thanks for the help!
But i think is confuse, why do not put a metod like getSelectedItem() ?!?

getSelectedItem sounds like a good idea, I'm tempted to implement it. If I get time I will add this for next release.

Hi!
Maybe a problem with combobox, in function clearlist().
If some item is selected, when called clearlist(), that doesn't remove the item that is selected! "
i need to put:
combobox->setCaption("");
To remove the info of the first item...
Tell me if i'm correct!?

Thanks for pointing this out! I have fixed it in the SVN. The fix is just as you pointed out, setting the caption to "". When/if I implement using a ListItem instead of just the caption, I'll need to remember to change this.

I think I made a function for ComboBox: addOnSelectionEventHandler.
Don't have access to code, but I'm pretty sure it's there.

Hey Huaner. I didn't test ScrollBar's with ListBox, I'm currently working on it now. Sorry for the wait.. Scrolling isn't so easy to implement, and the ScrollBar's are giving me problems, especially with the amount of customization I want to allow with them.
I will update the SVN thread when I have completed the Scroll components. I thought I'd finish them this weekend, but now it's looking more like Tuesday/Wednesday. Sorry again for the delay.

I've decided to revamp Menu's Lists, and the ComboBox, so I will need some more time before Scrolling works with the ComboBox. I think everybody will like these new changes.

Sorry for bringing this thread up, but I didn't want to create a new one
Is it possible that ComboBox::getSelectedItem() returns a NULL pointer if I want to get it when first selecting an item and then pressing on a button?
I think the reason is:
ComboBox::onMouseLeaves(const EventArgs& args)
{
mHighlightPanel->setVisible(false);
mHighlightedItem = NULL;
.
.
.
}
So maybe there should be a mActiveItem or something like that?

I reviewed my code, and realized it was a bad way of recording the selected item. I've changed it now, I'll commit to SVN and re-upload the zip for everybody to use.
Thanks for pointing this out!

Has anyone got an example of exactly how this is used, I need to use it but being a bit silly I cant seem to get it working. I get various errors, when I try different things.
Thanks in advance.
class foo
{
public:
foo()
{
// ... some stuff
combo_box -> addOnSelectionEventHandler (&foo::handlerFunction, this);
}
void handlerFunction (const QuickGUI::EventArgs&);
};
Edit: misplaced QuickGUI::

I have had another user have a problem with the ComboBox, I may have been hasty in updating the code last night. Tonight I will make a small test in the QGUI demo app to verify all parts work correctly:
Selection (get/set/mouse clicking items)
Highlighting
Clearing Selection
Not really related to your problem, but thought I'd give a heads up with ComboBox anyway.
Zini's example works, here is another:
// Note that "this" is the object used to call the function. It should be
// an instance of Class myClass.
myComboBox->addOnSelectionEventHandler (&myClass::myFunction,this);
void myClass::myFunction(const EventArgs& args)
{
...
}
