I made a Javafx application that works fine on PC. Now, I try to transfer it to Android Smartphone. To do that, I use JavaFXPorts (Gluon), with Eclipse and Gradle.
Now, I am stuck with a very simple example:
void showPopUp() {
Button button = new Button("Action do do"));
HBox.setMargin(button , new Insets(10, 30, 10, 30));
button .setOnAction(e -> {
actionToDo();
});
Scene scene = new Scene (button, 100, 200);
Stage stage = new Stage();
stage.initModality(Modality.APPLICATION_MODAL);
stage.setScene(scene);
stage.show();
}
Have you an idea of the reason?
Thanks
Here is the whole code with:
a periodic task (it works fine)
a delayed task (it works fine)
a button "btn" that displays the modal PopUp. The touchScreen on it works fine and allows to go to the PopUp
the PopUp with 2 buttons boutonPopUpA and boutonPopUpB that are added to the HBOX boutonsMenuPrincipal
and a stage with its scene "connected to" boutonsMenuPrincipal
In the popUp, boutonPopUpA and boutonPopUpB are displayed but inactive (No generated trace on a touchScreen)
