Windowbuilder on Linux Mint XFCE: drop-down selector obscured by vertical scroll bar #795

Closed MHNixon closed 4 months ago

MHNixon commented 4 months ago

Please forgive this newbie if the above issue has already been solved! For some 10 years I have been using Eclipse with Windowbuilder to write java apps. However with the last couple of updates I've noticed that when I try to change a swing objects properties in the designer, the vertical scrollbar almost completely obscures the drop-down triangle. Only with careful mouse positioning can I get at the icon and change a property. The attached screenshot should hopefully clarify my issue. I've tried several command line and environment settings relating to GTK without any success.
[Linux Mint 21 XFCE] I do hope someone can assist! eclipse_windowbuilder_issue about_eclipse

Out of curiosity, can you try out whether the same issue happens with the upcoming Eclipse version? The IDE should drop sometime tomorrow. There is an issue with how scrollbars are rendered in GEF (the backend of the property table) on GTK, which isn't included in the current release.

See: https://github.com/eclipse-platform/eclipse.platform.swt/issues/1182

When overlay scrolling is enabled, it's also quite a pain to use...

I think it makes sense to force the scrollbar to show up. Then this should sort itself out.

Thanks for the feedback, Patrick. Seems a "thinner" semi-transparent scrollbar, or forcing a re-sizing what of objects is what window builder needs in this particular context. Surprised that the dropdown list boxes don't shrink to accomodate the scrollbar. Scrollbar issue only manifests itself when you click the "advanced properties" icon.

Fixed via #803 and https://github.com/eclipse/gef-classic/pull/459. Overlay scrolling has been disabled in general, as the buttons might otherwise be obscured.

@MHNixon Can you check out the upcoming nightly build and see whether this issue still occurs? Also note that this requires changes introduced with the latest GEF nightly build.

Unrelated, but you might want to consider removing/editing your previous post. I don't really understand why GitHub thought it's appropriate to post your phone number...

Latest Windowbuilder nightly with Eclipse 2024-03 broken. I have downloaded Eclipse 2024-06 & will install this & test again.

WindowBuilder depends on the latest version of SWT, in order to use the method introduced with https://github.com/eclipse-platform/eclipse.platform.swt/commit/eb0f99db46d5ee8f6c345d8a3096efb401b41a03.

This method doesn't exist in the 2024-03. I've created https://github.com/eclipse-windowbuilder/windowbuilder/pull/804 to raise the lower bound, to reflect this dependency.

  1. completely removed Eclipse 2024-03, .p2, config files
  2. tried running Eclipse 2024-06 installer, but it kept timing out
  3. Removed OpenJDK 17
  4. Installed OpenJDK 21
  5. Downloaded & installed Eclipse Runtime 2024-06
  6. Can not update: "this installation has not been configured for software updates..."
  7. Can not install Windowbuilder: "profile SELF is not registered...."

This is way too much trouble trying to install Eclipse, so I have decided to abandon Eclipse altogether & switch to Netbeans: it just works out of the box without all these problems.
Thank you for your efforts, though: much appreciated. It seems Eclipse is not really recommended for Linux platforms based on my experience. [Linux Mint 21 XFCE]. I have used various versions of Eclipse since 2008, mostly with success, but at age 76 I haven't enough years left to spend just trying to get something to install correctly. ~/eclipse$ ./eclipse WARNING: Using incubator modules: jdk.incubator.vector Jun 20, 2024 7:15:13 PM org.apache.aries.spifly.BaseActivator log INFO: Registered provider ch.qos.logback.classic.spi.LogbackServiceProvider of service org.slf4j.spi.SLF4JServiceProvider in bundle ch.qos.logback.classic 19:15:16.037 [Start Level: Equinox Container: 6515c989-6192-4020-8601-82eeef568717] DEBUG org.eclipse.jgit.internal.util.ShutdownHook -- register org.eclipse.jgit.util.FS$FileStoreAttributes$$Lambda/0x00007f65901ea608@1c13fafb with shutdown hook 19:15:16.037 [Start Level: Equinox Container: 6515c989-6192-4020-8601-82eeef568717] DEBUG org.eclipse.jgit.internal.util.ShutdownHook -- register org.eclipse.jgit.util.FS$FileStoreAttributes$$Lambda/0x00007f65901ea608@1c13fafb with shutdown hook BUG In pixman_region32_init_rect: Invalid rectangle passed Set a breakpoint on '_pixman_log_error' to debug
