JavaFX MouseEvent continues when I remove the object it happened on
- by Kyle
It took me a while to realize what was going on with mouse events going through my blocking dialog boxes when I closed them, but I finally figured out why. I still don't know any good way to fix it.
I have a custom dialog box (that blocks the mouse) with a close button. When I click the close button, I remove the dialog box from the scene, but JavaFx is still processing the MouseEvent and now it finds that there is nothing blocking the screen behind where the cancel button was, so that component receives a MouseEvent. How do I make the mouseEvent stop processing when I see that they pressed cancel and remove the dialog box? Or, is there a way to make the removing of the dialog box not happen until after it is done processing the MouseEvent?
Example Code for the problem:
import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.shape.Rectangle;
import javafx.scene.input.MouseEvent;
import javafx.scene.control.Button;
var theScene:Scene;
var btn:Button;
Stage {
title: "Application title"
scene: theScene= Scene {
width: 500
height: 200
content: [
Rectangle{
width: bind theScene.width
height: bind theScene.height
onMouseClicked: function(e:MouseEvent):Void{
println("Rectangle");}
},
Button{
layoutX: 20 layoutY: 50
blocksMouse: true
text: "JustPrint"
action:function():Void{
println("JustPrint");}
},
btn = Button{
layoutX: 20 layoutY: 20
blocksMouse: true
text: "Cancel"
action:function():Void{
println("Cancel");
delete btn from theScene.content;}
},
]
}
}
When you press "JustPrint" you get:
JustPrint
When you press "Cancel" you get:
Cancel
Rectangle
