Is there a way to log every gui event in Delphi?
- by awmross
The Delphi debugger is great for debugging linear code, where one function calls other functions in a predictable, linear manner, and we can step through the program line by line.
I find the debugger less useful when dealing with event driven gui code, where a single line of code can cause new events to be trigerred, which may in turn trigger other events.
In this situation, the 'step through the code' approach doesn't let me see everything that is going on.
The way I usually solve this is to 1) guess which events might be part of the problem, then 2) add breakpoints or logging to each of those events.
The problem is that this approach is haphazard and time consuming.
Is there a switch I can flick in the debugger to say 'log all gui events'? Or is there some code I can add to trap events, something like
procedure GuiEventCalled(ev:Event)
begin
log(ev);
ev.call();
end
The end result I'm looking for is something like this (for example):
FieldA.KeyDown
FieldA.KeyPress
FieldA.OnChange
FieldA.OnExit
FieldB.OnEnter
This would take all the guesswork out of Delphi gui debugging.
I am using Delphi 2010
