There’s a certain control which I don’t have the source to (Steema TTree) it doesn’t send a help message when help is requested through the form. (clicking the ? near the X on the dialog, then clicking the TTree)

I can just call help directly on the form and pass in my own helpmessage, but I don’t know whether the form is in help mode.

The form’s cursor is acutally 0 even when it has a ? next to it… That I find odd.

Anyway, I know I’m hacking my way through this, but I don’t care. All I want to know is if there is a way to tell whether the user is requesting help and currently has a ? next to their cursor

    Torry helped 

     procedure wmNCLButtonDown(var Msg: TWMNCLButtonDown); message WM_NCLBUTTONDOWN;
 procedure wmNCLButtonUp(var Msg: TWMNCLButtonUp); message WM_NCLBUTTONUP;

    I overrode those functions to set a global variable

     fHelpMode : Boolean

    to true when

     if Msg.HitTest = HTHELP then
      fHelpMode := true;

    That allowed me to know when if the user was requesting help and I could override a mouse event on the TTree to do my help pop-up.
