Greeting,
(https://stackoverflow.com/questions/48937412/node-snapshot-causing-layout-issue)
Using JavaFX 9.0.4 I'm embedding some 3rd party Swing content in a
JavaFX app. The 3rd party content already has its own preferred size,
so I'm wrapping it with a StackPane to stretch it out...
However, when node.snapshot() is called this causes the SwingNode to
jump back to its preferred size, manually resizing the window causes
it to fill the window again.
I've also identified this only occurs if the scene is first shown
without content and the content is added later.
Is this a bug? How can I work around it?
The following example recreates the issue
public
class
NodeSnapshotFunny
extends
Application
{
@Override
public
void
start
(
Stage

)
throws
Exception
{
SwingNode
swingNode
=
new
SwingNode
();
Button
button
=
new
Button
(
"Test"
);
button
.
setOnAction
(
event
->
{
WritableImage
image
=
button
.
snapshot
(
null
,
null
);
});
StackPane
stackPane
=
new
StackPane
(
swingNode
);
Scene
scene
=
new
Scene
(

stage
.
setScene
(

);
stage
.
show
();
stackPane
.
getChildren
().
add
(
button
);
SwingUtilities
.
invokeLater
(()
->
{
JPanel
jPanel
=
new
JPanel
();
jPanel
.
setPreferredSize
(
new
Dimension
(
300
,

));
jPanel
.
setBackground
(
Color
.
red
);
swingNode
.
setContent
(
jPanel
);
});
}
public
static
void
main
(
String
[]
args
)
{
launch
(
args
);
}
}
