Hello Dirk,

I have to apply painter for a editor component which has three labels and four text components. Predefined painters are not suitable for that so I am thinking to create an image by custom drawing same as editor component? Please suggest if there is any good approach than what i am thinking.

Thanks in advance.

Hi,

I'm not sure what you mean. First you need to differentiate between editor and painter. The editor is Control based, while the painter is simply drawing on the GC. If your editor is complex, I assume it is handled in a subdialog? Otherwise I'm not sure if NatTable supports a complex editor control inline. Never tried it before, so to be honest I'm not sure.

Implementing a custom painter is straight forward. You simply need to draw on a GC whatever you want to draw. Labels, Images or whatever. The TextPainter does nothing else.

Greez,
Dirk

Thanks for reply Dirk.

As in NatTable, odd row and even row have different background colors so according to that i want to set the background color in my image. but don't know how can i get that color to set in my image.

setWrappedPainter(new BeveledBorderDecorator(new ImagePainter() {
      @Override
      protected Image getImage(ILayerCell cell, IConfigRegistry configRegistry) {
     
      //how to get color......  


      return _image;
        }
      }));

Please suggest any appropriate approach to get the color according to odd or even rows.
Thanks in advance.

Not sure if it works because of possible time related issues (when is which style applied?), but technically this should work:

IStyle cellStyle = CellStyleUtil.getCellStyle(cell, configRegistry);
Color bg = cellStyle.getAttributeValue(CellStyleAttributes.BACKGROUND_COLOR);
