XTP 13.0.0.
I'm trying to enable/disable certain gallery items in an update-handler. I can't get it working.
 
ON_UPDATE_COMMAND_UI_RANGE(ID_ITEM1, ID_ITEM10, OnUpdateGalleryItems) // Never called!
 
Can it be done? So far I have only been able to enable/disable the whole gallery... :(
 
Thanks.

I solved it!
 
void CControlGalleryItem::Draw(CDC* pDC, CXTPControlGallery* pGallery, CRect rcItem,
                               BOOL bEnabled, BOOL bSelected, BOOL bPressed, BOOL bChecked)
{
    CXTPControlGalleryItem::Draw(pDC, pGallery, rcItem, bEnabled && IsEnabled(), bSelected, bPressed, bChecked);
}
 
Then I call SetEnabled() in my gallery-update-handler!

Actually, this doesn't solve it completely. The item is still clickable...
 
This is due to CXTPControlGallery::OnClick() where there is only a check for the enable-state of the gallery itself:
if (!GetEnabled())
    return;
 
 
Any ideas?

Hi,
 
in same Draw method you can set bPressed to False if IsEnabled() is false.

Sorry, but that doesn't work either...

bPressed &= IsEnabled();
 
The click is handled in the parent class, so I can click the item even if it's disabled/unpressed or whatever... This is definitely a bug in the parent class!
 
 
Next idea? :P

You can click it but visually you don't see it ?

I see it, but it's disabled (grayed out). Then when I click it, the command-handler is fired! The click should be eaten in this case! :(

This is still a problem :(. Any disabled items are clickable since CXTPGallery does NOT handle such states in OnClick()!
 
What should I do to disable clicking on certain items?! The items are drawn correctly...

I hope you realize this is indeed a flaw in the gallery code. Any improvements planned for 13.1?
