Custom cursor disappeared when passing over a listbox with a header defined.
[Dropbox - cursor over listbox.xojo_binary_project.zip - Simplify your life]
A tried to post a video in the forum showing this case but I cannot found the way, is there a help somewhere?
Seems a bug to me, but why are-you drawing the cursor instead of using a cursor ?
Draw your cursor,
Save the image,
import the image as cursor.
Search in the LR is needed as I forgot how to really do that.
it was just a example, in many cases I use an image:
var c as new mousecursor(Typhoon, 34,15)
App.MouseCursor = c
Do you think it’s a bug? I should create a feedback? The problem exits also using a picture cursor.
I do not know, I only used your example, then checked the code.
do you follow the rules while creating your custom cursor ?
(especially the size)
I checked there:
and I do not saw any size, so I suspect some are tempted to use the size they want.
A cursor 50 x 50 ?
Also, the ListBox may be able to change the MouseCursor when it is located in the Heading area (for changing a column width)…
Not the above:
App.MouseCursor = System.Cursors.HandOpen
behave the same in your project.
Looks like a bug. Someone can confirm that ?
It does not seem a size issue, if you use any other Apple Standard Cursor the problem subsist.
App.MouseCursor = System.Cursors.FingerPointer
When over a listbox with header defined it changes to the standard Arrow.
Your message appears after I sent mine. I was testing.
Yes, not a size problem (even if 50 x 50 is a hudge MouseCursor).
I resized to 20 x 20 (your project) = same behavior.
I modifyed your code to:
app.MouseCursor = Nil
Self.MouseCursor = Nil
Box1.MouseCursor = Nil
app.MouseCursor = c
No change, the custom cursor disappears…
My guess is that the cursor is changed to indicate that you can select something.
box.MouseCursor = c
to your SetCursorBack2 method just after app.MouseCursor = c
The cursor changes if the Box has a header defined and not, if it has not, this does not seem logical.
The app was an example to show the malfunction. In the real app I just want that the mouse cursor not change when passing over a listbox. And worse, sometimes after passing over the listbox it does not recover to the custom cursor.
