How do I detect completed resizing operations in JavaFX?

I have a stage, a scene and a WebView node When I expand the window to a larger size - things get very slow due to WebView What I want to do is fill the WebView with new space only when the window is resized (this is when I release the left mouse button on the resizable control / edge of the window) Now I can set the maximum value The default size for this node is - this will prevent it from expanding But how do you detect the actual events of the resizing operation completed on the window? By binding, I can verify that resizing occurs – but it is instantaneous (the properties of W & D change immediately without releasing the LMB), and I only need to perform the operation when releasing the LMB Suggestions?

I tried in event Addeventfilter is used on any's stage just to see if the event type is recognizable - unfortunately, it doesn't help

Solution

This answer applies only to your application using undecorated stage

On the undecorated stage, you can handle the decoration and operation of resizing by yourself; Allows access to the right hook to handle the completion of the resize operation

For a demonstration of how to implement a resize handle for an unmodified phase, see the windowresizebutton class in the assemble sample application source code Modify this class to add a setonmousereleased handler and implement WebView size modification in it

I really want to know why this is necessary, because I don't have any slowness to adjust the slowness of the window containing WebView - maybe it's because your application uses different content in WebView than I've always used
