Detect tab change in PageControl

Question

I have a PageControl on my form and i wish to detect when the user is selecting another tab.

How can i do this ? I am using Delphi 7.

I didn't find any event and waisting time developing my own pagecontrol is not exactly what i intend to do.

Answer 1

try this on show or create event of your form

 iThCrrntIndex:=PageControl1.TabIndex;  //the currently selected page

then on PageControl1Change event or PageControl1Changing event check

   if   iThCrrntIndex=PageControl1.TabIndex then
        begin
     //same page
   end
 else
   begin
     //new page selected..
   end;
