8271557: Undecorated interactive stage style by mstr2 · Pull Request #594 · openjdk/jfx

mstr2 · 2021-07-29T19:50:55Z

This PR introduces StageStyle.UNDECORATED_INTERACTIVE. This style is similiar to StageStyle.UNDECORATED, but adds platform-specific interactions to the window.

For all platforms, this includes move and resize behaviors.
On Windows, it also includes Aero behaviors (snap to screen edges, dock at top to maximize, etc.).

Additionally, on Windows this style adds window animations and a drop shadow (both of which StageStyle.UNDECORATED lacks).

This new style can be used to create custom window decorations without losing window interactions.

Applications that use this stage style need to provide an implementation of WindowRegionClassifier to let the JavaFX windowing subsystem know which parts of the window should afford window interactions:

stage.initStyle(StageStyle.UNDECORATED_INTERACTIVE);

stage.initRegionClassifier(new WindowRegionClassifier() {
    @Override
    public WindowRegion classify(double x, double y, Node nodeAtPosition) {

        // Regions can be identified by the node under the current cursor position...
        if (nodeAtPosition == titleBar) {
            return WindowRegion.TITLE;
        }
        
        // ...or by window coordinates
        if (x < 10) {
            return WindowRegion.LEFT;
        }
        
        if (x > primaryStage.getWidth() - 10) {
            return WindowRegion.RIGHT;
        }

        return WindowRegion.CLIENT;

    }
});

If a window region is not returned from the classifier, no interaction will be available for this region.

This would be great for creating customized themes with different window decorations if that were to be supported some time down the line with this feature.

Is there anything blocking this from moving forward in the review process?

This PR is not yet ready for review, as I'm still working on some issues with resize flicker on Windows.

Haven-King · 2022-11-16T22:11:59Z

Any updates here?

TX256 · 2023-01-12T14:11:05Z

I think this is a very important PR.

Undecorated windows have become pretty much the standard nowadays for desktop apps, and the current state of affairs on Windows gives an unprofessional experience - as the minimize, maximize & restore animations are not displayed at all. Not to speak of Aero snapping.

Is there a possibility that this could be done for JavaFX 21?

leewyatt · 2023-01-13T02:57:25Z

Very useful PR, looking forward to it.

wow，A very splendid pr, especially looking forward to incorporating it into the official version

Anivie · 2023-01-13T03:14:00Z

I am very supportive of this pr, it is hard to imagine that this feature has not been proposed until now, it is very important to build a modern application.

Xiaobaishushu25 · 2023-01-13T03:14:51Z

nice，this PR Make it easy to customize the window

leewyatt · 2023-01-13T04:15:02Z

@Bridgekeeper Sorry. I discussed this issue in a javafx community, and many people found this feature very useful, so they replied to this discussion; there may be more people replying at a time; I have caused trouble to you, sorry.

leck995 · 2023-01-13T07:34:53Z

It‘s a userful PR,every time I need to do it myself. I hope the official can accept it.

dlemmermann · 2023-01-13T12:09:54Z

Would so love to see this happening.

palexdev · 2023-01-15T15:20:25Z

Can we have this by the next version?

tsayao · 2023-01-27T17:38:08Z

+    private void handleMoveWindow(int xAbs, int yAbs) {
+        window.setPosition(mouseDownWindowX + xAbs - mouseDownX, mouseDownWindowY + yAbs - mouseDownY);
+    }


On Linux this will be constrained by the window manager, so it's not possible to move the window outside of the desktop bounds, including panels.

This can be done by implementing a beginMoveDrag on glass that will call (on linux):
gdk_window_begin_move_drag

tsayao · 2023-01-27T17:41:52Z

To allow a custom decoration control, the part of the TITLE window region would have to be transparent to allow it to be more customizable, like this:

Notice the rounded borders.
