Delete Button in SimpleGraph

[stefano4jc]

I Downloaded the simplegraph editor demo. Then Im making some changes just for fun, for example, I would like to handle my self the Delete Button or VK_DELETE. When I use the OnKeyPress function in the SimpleGraph component, I realize that I can handle every single key!!! BUT the Delete button!, I am kinda frustrated because I dont know what is going on, besides this works for me in any other program but here I cant handle this Delete button. Does anybody have an Idea about what is going on?

Thanks a lot!

Hi Stefano,

I have not used TSimpleGraph, but according to ur description, the SimpleGraph component might trigger Key Pressing event internally, before it elevates to the upper level of OnKeyPress (which u are using...), so u can take a look at the TSimpleGraph source code to catch it; and if is so, u can drive a class from TSimpleGraph and override the KeyPress method to manage the behavior of class as u wish.

Amir is right. In other hand, you may try OnKeyDown event.
