Question

Buttons of a custom toolbar are not stacked vertically when switched to new acrobat mode

We have a plugin and we have a custom toolbar where buttons are attached to the toolbar. When we are in old acrobat mode the buttons are aligned vertically but when we switch to new acrobat mode the buttons are aligned horizontally. Is it a new feature from acrobat side or there is an issue and I have to handle for new acrobat mode. Can anyone guide me why this difference is seen in button positioning?

The new UI is not fully flushed out and has several issues. My plug-in toolbar buttons are displayed horizontally in the old UI and vertically in the new. Also, in the old UI the button icons appear correctly, where as in the new UI they appear as lego bricks. Have you seen this icon issue?

 

I think this horizontal and vertical bit is relative, because the orientation changes if there are a large number buttons. But regardless, you don't have any real control over it. It is whatever Adobe decides to do.   The real problem for me is the button icons.

Thanks Thom Parker for your reply.

 

Yes, we faced a similar issue where UI icon appear as lego bricks in the new UI. 

 

we solved the issue by reading the icons from PDF and pass it to button. We used AVIconCreateFromPDF, I think it might help you to solve the icon lego issue.
