ScreenGadget bugs

[drgolf]

Hello,

In the example : screengadgetmultiplewindow, on window2, tab splitter, move splitter on max right or max left : the app freeze.

I have an error message : accès mémoire invalide, ligne 217.

Very good lib.

Tested with pb 6.30 b3 x64 windows 11 pro.

Moved to regular bug forums, you can put all your ScreenGadget related bugs here so pf-shadoko have a quick overall.

Todo so, a little doc was very helpful...
Functions, their parameters ... and what they should do.
Or missed I the posts about that ?

Doesn't freeze.
I guess this happens under certain circumstances.

I found this bug. When entering non-english text, the text cursor is moved to the right of the text.

No crashes to report here on x64.

I echo Bisonte's sentiment that a simple list of the new commands, parameters & flags would be really useful in testing.

A few points regarding the ScreenGadgetMultipleWindow.pb sample:

The progress bars have a cosmetic issue when the values are down towards the lower end (you can see it in the video posted above).
The shift key has input lag, so keying something that contains occasional capitals (such as your name) will often miss the capitals.
Typical shift-select of multiple characters on an input box doesn't work, so you can't clear the box quickly & easily.
Keyboard inputs aren't repeating, so clearing an input took many presses of the backspace key.
Adjusting the rotation slider & clicking the 'show / hide' button a few times eventually caused Window 2 to just hide & re-appear instead of it animating on & off the screen.

What's the command to rename a ScreenWindows title?
Are tooltips implemented / going to be implemented?

This lib is a mimic of the regular gadget lib so it should be easy for PB coders to get a grip of it. Doc will be ready a bit later

Hi coders,

Other bugs:

- If you click on an unused area, the last gadget (or window) selected is affected.

- Animations don't always work.

Regarding:

- splitterstringgadget (drgolf): strange, I don't have this bug, do other users have this problem?

- stringscreengadget (User_Russian): maybe it's related to the alphabet used.
Can you try with skins 1 and 2 (first line of code in the example)?
I'm using 2ddrawing here.
Can you check if drawtext is in sync with textwith (using the same font)?

- Problem reported by pjay: this will be fixed.
The cursor offset relative to the text (string and editor) seems more complicated.
It depends on the font.
Can you tell me if you have the same problem with skin 1 (first line of code in the example)?

[User_Russian]

Can you try with skins 1 and 2 (first line of code in the example)?

The problem is only when choosing a skin 3. It's probably a font issue "ink free".
For some reason the function SetScreenGadgetFont() not work. I added after the line

Code: Select all

StringScreenGadget(40,180,460,250,34,"blablabla blabla bla",0)

this line

Code: Select all

SetScreenGadgetFont(40, LoadFont(100, "Arial", 24))

but the font did not change.

[Mesa]

Everything is fine.
Windows 10 64b with Mesa3D openGL drivers.

@ User_Russian:
For now, only PB_default is supported by SetScreenGadgetFont
(and before the creation of gadgets).

but the problem comes from SetScreenGadgetFont, I'll fix it

No crashes for me.
(I'm running PB6.30 x32 - Windows 10)

For now, only essential events are being managed.
