Setting button image during runtime by tribbium on 08-01-2009 at 12:51 AM
Note: This is in reference to buttons that are not using CustomLook where the image is set inside the default grey rectangular button.
An example button containing an image follows:
code:
<Control xsi:type = "ButtonControl" Id = "EditQuestion">
<Position Left = "56" Top = "105" Width = "80" Height = "13"/>
<Image>
<Name>add</Name>
</Image>
</Control>
I want to be able to change the Image used during runtime. Since the image is not encapsulated in an ImageElement, I cannot use the function ImageElmt_SetImageFile to set it. How would you go about doing this?

I'm fairly certain it's not possible, even using the API. Sorry.

I'm pretty sure it can be done by using the PlusWnd.SendControlMessage function and this.

How would you get the Elements Id? Or would it just use the ID of the button control?

quote:Good thinking, but I couldn't get it to work here. I created a HBITMAP from an image file and then tried to send its handle to a button control, but the button image didn't change. I think the button control of Plus! draws its image only on creation based on the XML and doesn't respond on messages such as BM_SETIMAGE. Too bad...
