CEGUI (Crazy Eddie's GUI) Forums

Hi everybody,

I am using a Listbox element and I do not know how to 'activate' the Vertical Scrollbar.

When I add a lot of items within the Listbox, automatically appears the vertical scrollbar on the right. BUT, clicking with the mouse on it, nothing happens, the scrollbar does not move.

What do I have to do to be able to use the vertical scroll bar?.

I have been looking for information about this in the forums and tutorials and I wasn't able to find it.

Where could I find what I need?.

did anybody have the same problem as me?.

hi Buckcherry,

you should found what you search for at properties level

http://www.cegui.org.uk/api_reference/namespaceCEGUI_1_1ListboxProperties.html

the "ForceVertScrollbar" property is what you looking for.

According to that:

Detailed Description
Property to access the 'always show' setting for the vertical scroll bar of the list box.

Usage:
Name: ForceVertScrollbar
Format: "[text]"
Where [Text] is:
"True" to indicate that the vertical scroll bar will always be shown.
"False" to indicate that the vertical scroll bar will only be shown when it is needed.

So, ForceVertScrollbar seems to be only to show or not the vertical scroll bar.

When it is needed, automatically appears the vertical scroll bar in my screen, but I can not use it. It's like it was deactivated, but it is shown...

Any idea?.

ok,

sorry i miss understood you'r question.

it's strange... some research ideas :

- basic but, are you injecting the mouse events in CEGUI, like mouse pressed ?

- what is the result of the getTotalItemsHeight (void) on you'r listbox ?

- did you modifi items after they are added to the listbox ?

hope it help

1. Yes, I am injecting the mouse events in CEGUI: mouse pressed and mouse moved

2. I can't access to getTotalItemsHeight because it's a private method

3. I modify the items BEFORE they are added to the listbox


Do I have to create any method like mousePressed for the vertical scrollbar?.

Please, HELP!

dumb question: do you also inject mouse release ?

Have you tried to look at the samples, check if it works there and if yous, you can search for differences to your code.

I have not found the mistake. I am getting crazy with this!...

Is it possible to paste some piece of code here, please?.

Thanks.

Please do.

It just works for me, did you try to create a new CEGUI project FROM SCRATCH using ONLY original CEGUI files/code snippets ?

Could you possibly post some piece of code here, please?.

The problem is still unsolved.
