Mouse over subitem TREEVIEW show image

[SergioFeitoza]

Is it possible to  put the mouse over a SUBITEM of a TREEVIEW and seeing an existing image ?

Something like in the figure attached . A part of code of a similar thing is very welcome

What I want to do here is more or less the same that happens when we put the mouse over the title of the posts in this forum (the whole message appears)

Something like this I guess:

Yes Sherzod. This is what I need to do. Can you post the code  of the mouse event ? Thanks in advance

Hi,

First of all, can you please open a ticket in support portal as feature request?

http://jira.fmsoft.net/servicedesk/customer/portal/4

 

And, can you tell me how do you add nodes to the treeview, designtime or runtime? Can you provide part of your code or a simple testcase?!

Hi Sherzod. I will open the ticket now. Below is the code for the creation of the treeview in DESGINTIME . Is not equal to the one in the unugui demo AllFeatures

procedure TMainForm.ConstructNavigator;

  S, S1, Path, SubS : string;
  sr: TSearchRec;
  Ls : TStringList;

  Nd,Nd1 : TUniTreeNode;
  Mt, Mt1 : TUniMenuItem;

begin
   sAplicacao := TStringList.Create;
   sDescricao := TStringList.Create;

               Mt.Add(Mt1);
