Opaque tooltip on Linux #220

weisJ · 2020-12-01T17:27:56Z

@weisJ This bug seems to still be appearing on Linux.

I'm on Arch Linux x86_64 (5.9.8-arch1-1).

It also seems to be incredibly hard to activate tooltips. They don't appear after hovering, but can in some circumstances be triggered with control + f1, however this is very hard to trigger.

This bug seems to still be appearing on Linux.

The popup for the tooltip is configured here:

darklaf/core/src/main/java/com/github/weisj/darklaf/ui/DarkPopupFactory.java

Line 97 in d47b78e

    
           protected void setupPopup(final PopupType type, final Component contents, final int x, final int y) {

It would be very insightful what PopupType the popup has.
Are you comfortable with building the project locally? You can start the tooltip demo using

gradlew runDemo --class ui.toolTip.ToolTipDemo

It also seems to be incredibly hard to activate tooltips. They don't appear after hovering, but can in some circumstances be triggered with control + f1, however this is very hard to trigger.

The laf shouldn't change how tooltips are activated. Do you experience the same issue when using the system look and feel?

On the demo it seems to be working ok. Probably something I'm doing wrong so don't worry about this part.

x4e · 2020-12-01T22:46:54Z

Actually I take back that last part. It seems that sometimes the tooltip is triggered as my System.out.println(type) in DarkPopupFactory.java is being triggered, however often no tooltip shows up.
This is likely related to the opaque problem in some way.

weisJ · 2020-12-01T23:00:51Z

Could you print out the component hierarchy of the tooltip together with the corresponding background colours?

x4e · 2020-12-02T08:58:30Z

Which variables are those stored in?

weisJ · 2020-12-02T09:03:05Z

You have to loop over the parents of the tooltip i.e.

Component p = content;
while(p != null) {
    System.out.println(p);
    System.out.println(p.getBackground());
    System.out.println(p.isOpaque());
    System.out.println("");
    p = p.getParent()
}

@x4e For the opacity issue please try to check out the linux/tooltip branch.

As for the tooltip not being displayed sometimes you might want to try to set System.setProperty("darklaf.animations", "false").

weisJ · 2020-12-21T20:20:38Z

@x4e I have published the linux/tooltip branch. It can be tested using com.github.weisj:darklaf-core-linux-popup:latest.integration as a dependency.

x4e · 2020-12-21T23:50:58Z

Thank You! That works a lot better.
There are still some minor issues highlighted in this video (https://youtu.be/-quKrqTuL40), being white background, tooltip being slightly displaced sometimes, and previous tooltips being visible in the background).
This is great though thanks!

weisJ · 2020-12-26T15:35:40Z

I just released another snapshot version for the linux/tooltip branch.
I had to deal with incorrect tooltip positioning multiple times already and it always was caused by system scaling factors. To make sure where to look for the problem could you log the following information for me:

GraphicsConfiguration gc = GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice().getDefaultConfiguration();
AffineTransform  transform = gc.getDefaultTransform();

System.out.println(gc);
System.out.println(gc.getDefaultScreenDevice());
System.out.println(transform);

Also which java version are you using?

x4e · 2020-12-26T22:00:36Z

Also which java version are you using?

OpenJDK 15.0.1

To make your code run I had to change it to the following (I believe it has the intended functionality):

var gs = GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice();
var gc = gs.getDefaultConfiguration();
System.out.println(gc);
System.out.println(gs);
System.out.println(gc.getDefaultTransform());

And the output is:

X11GraphicsConfig[dev=X11GraphicsDevice[screen=0],vis=0x21]
X11GraphicsDevice[screen=0]
AffineTransform[[1.0, 0.0, 0.0], [0.0, 1.0, 0.0]]

Does TooltipTest fail for you with the linux/tooltip branch?

x4e · 2021-01-03T17:53:55Z

Sorry for the late response.

gradlew test succeeds with this tooltip screenshot so I'm guessing that means that the test is suceeding.

Tooltips in my actual project do not work at all now, and just briefly blink a black square before going away.

weisJ · 2021-01-23T00:39:03Z

@x4e the new snapshot version com.github.weisj:darklaf-core-linux-popup:latest.integration should fix the transparency issue. Could you verify that this is the case for you?

weisJ · 2021-01-23T14:17:35Z

Positioning also shouldn't be an issue anymore.

x4e · 2021-01-26T00:05:48Z

Thank you so much! It works perfectly now. It's great to be able to maintain a project like this on so many different operating systems.
Feel free to close the issue.
