BGRA Controls

[andrew Bubble]

Hi Lainz

I am currently using BGRAControls V7.7, how do I upgrade to your latest.

Is it as simple as copying all the flies and directories from the latest and doing an IDE rebiuld.

yes

Due to compatibility issues, I need to install version 7.3 of the BGRA Controls, but the Online Package Manager installs version 8.0. Is there a way to force v7.3 to be installed ??

@petevick: no, OPM installs the version it has in its library. Most often it is the latest version reported by the component's author.   
But it is very easy to install the package in Lazarus manually. You download the component package you want to install ( bgracontrosl 7.3: https://github.com/bgrabitmap/bgracontrols/archive/refs/tags/v7.3.zip and the required bgrabitmap: https://github.com/bgrabitmap/bgrabitmap/archive/refs/tags/v11.5.8.zip ).
You unpack both archives and then move the unpacked folders to the "components" folder in the Lazarus directory.
You launch lazarus and in the menu select "Package > Opena Package File (lpk)" and then point to the file "bgrabitmap\bgrabitmappack.lpk" in the path where you placed the component. A package window will open, where you press "Compile". Then you again choose "Package > Opena Package File (lpk)" you point to the file you point to "bgracontrols\bgracontrols.lpk". In the package window, you press "Compile", and when the compilation is complete, you press "Use > Install". After rebuilding the IDE, the components should be visible on the component palette.

Thanks for the reply paweld, that sounds like just what I need. Many thanks

Hi.

What's wrong with the newest version that you need to get back to old version?

Just to see if we can do something.

Hi lainz, I'm sure there's nothing wrong with the newest version, it's just that I use Lazarus in various OS VM's to check and compile projects (Windows, Linux x64, x32 etc), I know it's not ideal, but there you go. I've just added another Linux flavour VM, so it's to keep the consistency across all VM's. I've since found the easiest way is to copy an existing Linux .lazarus folder to the new VM.
I suppose really I should get brave and update all of the VM's to the latest version

Hi Josh,

I've applied a fix on the dev-bgracontrols branch. It is as well related to FPC 3.2.3 as was the error you encountered with BGRABitmap.

Does it compile now?

Hi

Yep compiled and all appears good.

thanks for your rapid fix

You're very welcome.

I am glad to keep BGRABitmap and BGRAControls afloat

Hi

Is there something I missing when compiling aarch64. Heap trace report memory leaks when added a DTAnalogGauge.
I use the latest version 8
FPC 3.2.2
Lazarus V3

Added a timer with code below
DTAnalogLoad.Position:= Random (5000);
if DTAnalogLoad.Position > 3000 then
   DTAnalogLoad.FaceSettings.ColorEnd := Clred;
else
  DTAnalogLoad.FaceSettings.ColorEnd := ClLime;

Hallo @Lainz,

Thanks for keep updating both BGRABitmap and BGRAControls.
Your last improvement by adding a Color property of BCPanel was great!

I'd have four suggestions to TBCComboBox component (numbering below in order of increasing effort, more or less):

• adding a color property to set "original" component backgroud (see attached pic)
• adding a horizontal line between the items in combo box with width and color property
• Drop Down menu as one class -> one property like TBCButtonState
• separated class for triangle to set parameters like color, width, proportion, etc. Maybe it will be enough to add one of the buttons on the triangle's place? As design idea please see attached pic.

Please consider above suggestions while updating the components next time!

Best wishes,
Ernest

Hi all.

I have developed a small ProgressRing (like WinUI3 ProgressRing).
There are two modes: Determinate and Indeterminate.

Honestly, I'm not sure if I used Canvas2D correctly for drawing or should I choose CanvasBGRA?

Thanks. Unfortunatelly I have no time to implement new things. But feel free to add these yourself if you can and provide a pull request.

Thanks. I've added this to dev-bgracontrols with the demo app as well.
