Creating component icons

[bobonwhidbey]

I've created a component (stringgrid descendant) which is now available on myPalette.
I've created a 24 x 24 pixel PNG file for the desired icon.
I've installed & used LRS Explorer 1.0.0.1 and it appears to have correctly created an LRS file. At least when I open the LRS file in the LRS Explorer, I see MyGrid(PNG) in the Resources List, and I see the icon in the Resource Viewer.

In my component file I've placed.

Code: Pascal  [Select][+][-]

1. procedure Register;
2. begin
3.   {$I MyGrid.lrs}
4.   RegisterComponents('MyPalette', [TMyGrid]);
5. end;

 

When I compile the package which holds this component, [and of course rebuild Lazarus in the process] the icon shown on my palette is the default one (red, green, and blue boxes) instead of the desired icon.

What have I done wrong?

I discovered that it's easy to link up a 24 x 24 pixel PNG file with a new component so long as you do this when the component is first created. After clicking package -> Add -> New Component there is a clearly marked button to add the desired PNG file. Works great!

Is there some way to add a PNG icon after the component has been created.

Open the resource with a text editor and ensure that it has this format:

LazarusResources.Add('TMyPallete','PNG',[
...
The name of the component must be in.

You are right, icons must be 24x24 pixels. The resource name must match the component name. You can add the icon also to a res resource.

In order to add an icon later you just have to rebuild the ide.
