Hello Andrew, actually i have a DrawFilter for a ToolbarManager and i place an onto a PopupMenuTool in UIElementDrawFilter.DrawElement() because i like to offer an additional user interaction on every menu item. It all works fine but I just can't get it to show only the image (a png with transparent background) without the border and the background color of the button (like an menu item image is displayed).

Hello Thorsten,

I am still a little bit confused as to what you are drawing on your PopupMenuTool’s child tools in this case? From your descriptions in this thread, it sounds like you are drawing a Button with an image inside, but I am not certain on this.

Would it be possible for you to please provide a sample project on this matter that shows what you are drawing, or perhaps just provide the code you are using for your DrawFilter for your PopupMenuTool?

Please let me know if you have any other questions or concerns on this matter.

Hello Thorsten,

I have been investigating into the DrawFilter you have provided, but to be honest I’m a little unsure of the behavior that I am seeing with it. So far, I have not been able to get it to work on my end due to a few missing dependencies as well as the condition that “drawParams.Element” is a PopupMenuItemDescriptionUIElement.

The part that I am rather unsure of in this case is this line and the lines that follow it:

IEnumerable<ImageAndTextButtonUIElement> buttonChildElements = parent.ChildElements.OfType<ImageAndTextButtonUIElement>().ToList();

This makes it sound like you already have a button of some sort within your PopupMenuTool, but in the lines following it appears that you essentially duplicate it and then re-add it to the parent. I might just be misunderstanding the items or objects that you have within your PopupMenuTool, but it seems to me that if there already is a button within your PopupMenuTool, your requirement may be able to be achieved without the use of a DrawFilter?

Would it be possible for you to please provide some additional information on the actual objects / tools that you are placing within the parent PopupMenuTool in this case?

Please let me know if you have any other questions or concerns on this matter.

Hello Andrew, hello Mike,

I have adapted Mike's last sample to my project. Now everything works fine for me. Thanks a lot for the support.

Regards

Thorsten Pontow

Thank you Mike! I will have a look at your updated sample.

Hello Andrew,

I used a CreationFilter with your image as a test and it still didn't work. But your example works correctly. I thought about what the difference between our implementations could be and suddenly I came up with the solution! We use a style (.isl file). When I removed the style usage everything was as I wanted it.

But since we have to use the style mandatory, my question is, what inside the style file do I have to change and how to make it work? I will add our style file as an attachment. Can you help me with that?

Regards

Thorsten Pontow
