Re: Problem with GtkTreeSelection

[Bob Caryl <bob fis-cal com>]

Hey John,

Yes, setting the focus to the GtkTreeView will indeed make the blue selection 
cursor appear, and I am able to do that the same way you do in your 
example... the problem is that the search I am doing is with a dynamic search 
image being entered into a GtkEntry widget by the user.. so changing the 
focus to the GtkTreeView in order to make the blue cursor appear is not a 
viable option, because as in your example, it requires the user to click on 
something to regain focus for the GtkEntry widget where the search image 
entry was occuring.

The other information about themes is probably more useful.  I was not aware 
that the selection cursor appeared as a grey color and I probably need to 
investigate that situation. 

Thank you so much for all the effort you put into answering my question.  

Best regards,
Bob Caryl
