Dialog tray taking wider width than the wizard when we maximise the wizard dialog. It can't be customised.

[divzz95]

Let's make sure issue is not already fixed in latest builds first.

• I verified I can reproduce this issue against latest Integration Build of Eclipse SDK

Steps to reproduce

From a fresh installation and clean workspace:

• Open any object wizard. eg. Java class
• Click on Help icon at the bottom left.
• Now maximise the wizard.
• Help tray can be seen taking wider area.

I tried

• To customise the ResizeListener added in TrayDialog.java in my subclass
• But, it is private and final.
• I need to use the tray dialog for my customised requirement and I am not able to change the resize behaviour.

I expected: The size of the tray dailog can be scaled as per our requirement

But got: Not able to customise the resize code.

Tested under this environment:

• OS & version: Windows 11
• Eclipse IDE/Platform version : 2024-12 (4.34)

Regular size wizard

Maximized wizard

Community

• I understand reporting an issue to this OSS project does not mandate anyone to fix it. Other contributors may consider the issue, or not, at their own convenience. The most efficient way to get it fixed is that I fix it myself and contribute it back as a good quality patch to the project.

i do not fully understand the issue

• Help tray can be seen taking wider area.

"wider" then what? it would help to understand the issue if you draw your expectations into the screenshots.

To customise the ResizeListener added in TrayDialog.java in my subclass

If its only a problem of you custom subclass you should provide a PR with a suggestion how to give you the needed API.

Out of curiosity, what behavior would you like to implement instead of the default one?

I am reusing the Tray dialog to show some UI content when clicked on the button which is added next to help button. In this case, when I maximise the wizard, I don't want the dialog tray to take the wider area than the wizard area. How can I achieve this.?

I updated the title for better understanding.

OK, so you're showing different content then (ie not the help, but some browser or whatever else control).
Have you tried adding another ResizeListener on your dialog? If this resizeListener is added after the default one, then it can override the behavior (eg change some preferredSize on the layout and then call requestLayout to refresh)

[divzz95]

The TrayDialog class doesn't provide a getter method for accessing the trayControl. This makes it difficult to set the layoutData for trayControl in my class. Adding another ResizeListener to my dialog is unsuccessful.

To meet my UI requirements, I need to modify the data.widthHint variable to a specific value within my class.

Can anyone provide guidance on how to achieve this?
