TSpeedButton & TImageList

[rpetges]

Hi all,

I use TSpeedbuttons in combination with glyphs ( see screenshot ) to modify the appearance of button icons for enabled and disabled state. For High DPI I loaded different icon resources based on the scaling in Windows OS.

Newer versions of Lazarus provide a more elegant way to do this with TImageList and the Scaled property. The TSpeedButton images  ( PNG format ) scale fine depending on the Windows scaling value, but how can I get back the feature that the image changes between an enabled/disabled state of the button ?

The only solution I found so far is to add the "enabled" and "disabled" glyph to the TImageList and then switch the TSpeedButton.ImageIndex property to select the corresponding image.

Best regards

In Laz/main, TSpeedButton and TBitBtn have are several imageindex properties

Code: Pascal  [Select][+][-]

1. type
2.   TSpeedButton = class(TCustomSpeedButton)
3.   published
4.     ...
5.     property DisabledImageIndex;
6.     property HotImageIndex;
7.     property ImageIndex;
8.     property PressedImageIndex;
9.     property SelectedImageIndex;
10.     ...
11.   end;
