Can't get CWndContainer::OnActivate to activate

[Daniel Cherry]

Hi all,

Has anyone got the bool CWndContainer::OnActivate to fire? I need to know when the container is active so I can put a highlight around the control, but i just can't seem to get it to fire and I have tried lots of different methods.

Any help will be greatly appreciated. 

 

Kind regards

Dan.

For any element you want to get "OnActivate"? On the basis of class CBmpButton or another?

[Daniel Cherry]

Hi - I can get it to fire for a CBmpButton inside the CWndContianer, but no matter what I try I can't get the CWndContianer.OnActivate to fire. Thanks Dan.

Share your code into two files: an indicator and class. (For example, a file from the folder: ...\Terminal\*** 8209F7...F37..BF55...1FF075\MQL5\Indicators\Examples\Panels\SimplePanel).

Hi barabashkakvn - I have attached the two files as requested. Kind regards Dan.

It does not work.

mytradertools :

Do you mean my code does not compile and run, or the OnActivate() of CWndContainter does not work? Regards.

Pay attention to control CBmpButton. In this control OnActivate () will work.

[Daniel Cherry]

Yes, agreed -  CBmpButton OnActivate works fine, I can get that to fire ok and it descends CWndObj not CWndContainer.

I can't get CWndContainer to fire and I can't see that I am doing anything wrong. Thanks Dan.
