Maybe Strange behaviour...
« on: July 08, 2024, 02:54:39 am »
I am using a counter on every form that increases the certain value (lets call it Tag).
When is show (in the on show-event) a from this Tag is increased by one.
And depending on this Tag certain things happen on that form.


So far so good.


Next I set the previous form (the form that calls the next form) to fsNormal and the form that is called up to fsStayOnTop.


On my Mac the this works perfectly.
But when I run the same code on a windows machine the Tag is increased by one every time I change the form status.


Can anyone confirm this so we can make a bug report?

You mean that changing FormStyle causes an OnShow event?
If so, please file a bugreport.

simple logic
I suggest to use TForm.BringToFront and its opposite TForm.SendToBack instead of using fsStayOnTop and fsNormal that are not opposite eachother

Yes but I want it confirmed before I add a bugreport

If changing the formstyle also changes which form becomes active, then an OnShow is to be expected, if the same form remains active then it would be a bug (or at least the behaviour across WS is not the same).

Well, there are great differences between widget sets. I would not say inevitable or unsolvable, but using widget set particular things may put your expectations on the wrong path.
In general, instead of the dreaded tag that I wrote about this week, simply keep some global variable, a class variable or inherit a new class. Tags are evil.

objects are fine constructs. You can even initialize them with constructors.

Maybe you could publish (Menu / Project / Publish project ...) a minimal project that show behavior you consider erroneous.
