我尝试使用
我该如何使用
下面是MVCE:
TToolbar
、TActionList
、TSpeedbutton
和TImageList
创建了一个工具栏。我使用32像素的正方形图像,但是当我在TSpeedButton
中通过ImageIndex选择图像时,图像大小小于32像素,我认为是16像素。我该如何使用
TImageList
设置TSpeedButtons
中图像的大小?下面是MVCE:

TForm50 = class(TForm)
ActionList1: TActionList;
ImageList1: TImageList;
SpeedButton1: TSpeedButton;

end;
var

implementation
{$R *.fmx}
end.
