Thanks for testing, new release

Fixed transparency for linux in slider

[bobby100]

Hi lainz,

I am using Lazarus 2.2.6 on Win10, and there is a problem with BCFluentSlider in the latest release (screenshot in attachment):
The position is wrong, and the slider length is wrong.

Is there a compatibility problem with Lazarus 2.2.6?

I didn't update to latest Lazarus because I have 2.2.6 on all my machines (Win, Linux, OSX and FreeBSD), and I have fear of updating it in on OSX because it was a hell of the job to get it working at all, and I do not remember what and I how I get it working.

I tested in Mint 32 bit, lazarus 2.2.4, no problems... I don't know in 2.2.6

Tested on Mint 64 bit with Lazarus 2.2.6 - same problem like on Windows 10.
Horizontal slider is OK, but vertical is messed up.

Tested in latest Fixes.

Same bug only with designer. The example created with code works fine.

Guys, give me some time, I'll check.
My apologies, I thought I tested it well
....
Done.
1) Change line 344
Was:

Code: Pascal  [Select][+][-]

1.  Bitmap.DrawLineAntialias(x + xy1, y, x+ xy2, y, c, FBorderWidth);

Now:

Code: Pascal  [Select][+][-]

1.  Bitmap.DrawLineAntialias(p.x + xy1, y, p.x+ xy2, y, c, FBorderWidth);

2) Add a new line

Code: Pascal  [Select][+][-]

1. procedure TBCFluentSlider.SetOrientation(AValue: TSliderOrientation);
2. var
3.   k: integer;
4. begin
5.   if FOrientation=AValue then Exit;
6.   k:=abs(ord(FOrientation) - ord(AValue)) + 1;
7.   FOrientation:=AValue;
8.   if csLoading in ComponentState then exit; // <<<----- Add this
9.   if odd(k) or (Width=Height) then
10.     DiscardBitmap
11.   else
12.     SetBounds(Left, Top, Height, Width);
13. end;  
14.

Hi guys!

I'm having a tough time updating the BGRA Controls package. Actually, the package installs successfully, but the new components (BCExpandPanels, BCFluentProgressRing, BCFluentSlider) don't appear in the component palette.

I've already tried to uninstall and install it again, recompile clean, build Lazarus clean, but nothing worked. The package compile and installs without errors. I downloaded the package via OPM.

I'm missing some step or something simple, maybe. Any ideas how to solve this? I really want to try the new components.

OPM should work fine.

If doesn't works try uninstalling bgracontrols and downloading from github releases.

Then open the package file and click on install, then rebuild lazarus.

This release is a fix, because I did the previous releases wrong, sorry, now the lpk has the correct version.

How can I add keyboard handling to a TBGRAGraphicControl descendant?
I need the events like OnKeyPress, OnKeyDown etc.

I am working on a slider component, and I would like to control it with + and - keys on the keyboard.

[lainz]

Only tbgravirtualscreen can handle keyboard

If you turn on KeyPreview for the form that the slider is on, you could then possibly use the forms OnKeyUp or OnKeyDown event to intercept when + and - keys are pressed.and therefore change the sliders value to suit.

It won't work with 100 sliders on the form.

@lainz - I can't find anything in tbgravirtualscreen related to keyboard.

Is a TWinControl descendant, check the parent (several times up) of TBGRAVirtualScreen...
