Greetings to all!

I’m starting to develop in Delphi 10 Seattle, before I used Delphi 7. I’m trying to create a toolbar, I’m using Ttoolbar with a Tactionlist, Tspeedbuttons and Timagelist. I’m using square images with 32px, but when I choose the image, by Imageindex, in Tspeedbutton, the image is smaller than 32px, I think it is with 16px.

How can I set the image size in Tspeedbutton using a Timagelist ?

          end>
      end>
    Left = 88
    Top = 20
  end
end

In the above example I am using only Tspeedbutton and Timagelist.

Thank you!

God bless us!

Let’s say we have Speedbutton1 (Tspeedbutton) and Imagelist1 (Timagelist)

The image size will be set in the Timagelist properties, Height and Width, if you assign 32 and 32 respectively and only after adding an image to the Imagelist of the size of 32px and also the size of the Speedbutton is greater than or equal to 32px side the size of the image shown will be 32px.

If you add the image before setting these measures it will happen that the image will be smaller than desired.

To assign an image of Imagelist to Speedbutton just put the following code...

ImageList1.GetBitmap(0, SpeedButton1.Glyph);

Being 0 the image index in Imagelist1.

  • Thanks @cava for the help. The Timagelist set the size to 32px for height and width at the time I enter the images, and also later when I define your orders (they come by default with 16px), but even done this did not solve the problem. I didn’t make the addition through code, I made it straight through the component.

I consulted forums and continued searching on the internet and am posting an option to solve the problem.

The size of the image in Tspeedbutton is set through a stylesheet (stylesheet), and only by this option it was possible to change it.

How to change:

First click with the right click on any Tspeedbutton of your form, and choose the option Edit Default Style....

clique com o botão Direito em qualquer TSpeedButton do seu formulário, e escolha a opção Edit Default Style...

In style editing mode, in panel Structure locate and select the option glyphstyle: Tglyph. In the Object Inspector, search for for size. Note that the height(Height) and the Width(Width) will be with the value of 16 (pixels), change its values to 32 or the size you want.

When you’re done click the Apply and Close button.

Done this, all Tspeedbuttons will present the images with 32px or in the size you set.

Observing: The size of Tspeedbutton should fit the size of the image you set, or it will be resized.

Hugs and thanks to all for your help!
