Re: [MSEide-MSEgui-talk] Artifacts in form scrolling (was tdirdropdownedit with statfile)

Hello Martin.

I am busy with the mercyless test of MSE dock.

Many wow.

At the moment I did only find this strange:

When docking all the windows into main window, sometimes the height of the
scrolled design canvas is too high.

See video:
mse_scrollheight.mp4
  


What cause that random different height ?
I did try many things, but always, randomely, a wrong height is assisgned.


And how to now if a scrollbar is visible ?

Something like:
if container.frame.sbvert.visible then

Thanks.

Fre;D

OK, removed that rounded "global"  frames. (that was not nice in fact).

Now, scrolling main form is perfect.

Well, MSE dock was hardly and deeply tested.

Verdict:

There are no limit.
Time to create now.

Many thanks and wow Martin.

in uos code line 2878:

for x := 0 to (Data.OutFrames div ratio) do ...

Must be:

for x := 0 to (Data.OutFrames div ratio)  -1 do ...

Many thanks Martin and Heaptrace. ;-)

And for the memory leak:

All the created msetimers must be freed on Form.OnDestroy.
--> Done: -->

Heap dump by heaptrc unit
72271 memory blocks allocated : 39115233/39248848
72271 memory blocks freed : 39115233/39248848
0 unfreed memory blocks : 0
True heap size : 753664
True free heap : 753664

OK, I will study it.

Many thanks Martin.
