Hi

I would like to see MyBitmap.with from the debugger. I tried to add

MyBitmap.width

In the watch list but this didn't work. I got

<Error: Type TBITMAP has no component named WIDTH.>

Is there a way for me to see component details like width in the
debugger.

Thank You.

You can (temporary) use a variable when debugging:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i var 
TestValue: LongInt; // ...   TestValue := MyBitmap.Width;

In the debugger you can query properties which map directly to object
variables, i.e. which do not have a getter function, usually by asking
for the property name with prefix "F", e.g. bitmap.FPixelFormat for
the pixelformat. Unfortunately, the property "Width" is provided by a
getter function GetWidth and thus cannot be evaluated this way, and
you must use Handoko's way.
