I have created a custom ComboBox that uses a ListView with a TextField in the footer, that's used to dynamically add options to the ComboBox.
The problem is, that as soon as the popup loses focus (so when the TextField receives focus), the popup gets closed.
I tried to force the popup to stay open, which does work, but then prevents the TextField from receiving focus (I guess because the popup regains focus as soon as open() is called).
ComboBox {
// ...
popup: Popup {
property bool forceOpen: false
onClosed: {
if(forceOpen)
open()
}
contentItem: ListView {
// ...
footer: TextField {
onPressed: forceOpen = true
}
}
}
}
I also tried all values for the closePolicy property of the Popup, but none of them helped.
I am using Qt5.11. The forceOpen solution used to work with Qt 5.10, but does not anymore.
Your problem should be fixed if you do not accept the focus on the ComboBox:
ComboBox {
focusPolicy: Qt.NoFocus
popup: Popup {
// ...
}
}
I'm trying to build a message window with App Bar on the top
This screen consist of Gluon App Bar on the top and VBox in bottom which has rest of the element shown in the screen.
Issue is when i click on the text area to enter text the App Bar goes out of scope.
Is there a way I can set App Bar to be always on top?
If you are deploying your app on Android, the TextField and TextArea controls include a built-in check: when those input controls get focused, if required the scene is moved up to prevent the software keyboard from hiding the control.
These translation affects the whole scene, so all the nodes in it (View, VBox, TextField, TextArea, AppBar, ...), will be translated as well.
So if you want to keep the AppBar node always visible and in the same top position, a possible fix could be counteracting that translation whenever it happens.
If you have a BasicView for instance (Gluon IDE plugin -> single view project), with a TextField control at the bottom of the view:
public BasicView() {
Label label = new Label("Hello JavaFX World!");
Button button = new Button("Change the World!");
button.setGraphic(new Icon(MaterialDesignIcon.LANGUAGE));
button.setOnAction(e -> label.setText("Hello JavaFX Universe!"));
VBox controls = new VBox(15.0, label, button, new TextField());
controls.setAlignment(Pos.BOTTOM_CENTER);
controls.setPadding(new Insets(20));
setCenter(controls);
}
you can modify it like this:
public BasicView() {
...
setOnShown(e -> {
MobileApplication.getInstance().getAppBar().translateYProperty()
.bind(controls.getScene().getRoot().translateYProperty().multiply(-1));
});
}
Make sure that the view is already added to the scene when you add this binding (to prevent a NPE).
Now when the textfield gets the focus, the whole scene will be moved up, and the appBar will be moved down the same amount:
Why does the JavaFX alert dialog fires the Platform.exit(); when I press the Enter key even though the focused button in the alert dialog is Cancel?
soaStage.setOnCloseRequest(new EventHandler<WindowEvent>()
{
#Override
public void handle(WindowEvent event)
{
Alert alert = new Alert(Alert.AlertType.CONFIRMATION);
alert.setTitle("Confirm");
alert.setHeaderText("Are you sure you want to exit?");
alert.setContentText("Press OK to exit, or Cancel to stay.");
alert.initOwner(soaStage);
Optional<ButtonType> result = alert.showAndWait();
if (result.get() == ButtonType.OK)
{
Platform.exit();
}
else
{
event.consume();
}
}
});
Default buttons are fired on enter
The OK button is fired when you press enter because it is a default button.
A default Button is the button that receives a keyboard VK_ENTER press, if no other node in the scene consumes it.
In the default JavaFX 8 Modena stylesheet, the default button is indicated by being a blue color rather than than the gray color of a standard button.
How to remove default button behaviour
You can remove this behavior from the alert dialog by not making the OK button a default button:
Button okButton = (Button) alert.getDialogPane().lookupButton(ButtonType.OK);
okButton.setDefaultButton(false);
I advise you not to do this, but instead to always leave a default button in alert dialogs.
On OS X, standard alert type dialogs have a default button which is triggered by enter even if another button is focused, so the standard behavior in JavaFX is consistent with that. Note: to allow this behavior in default dialogs in OS X it is necessary to enable full keyboard access.
If you do change the OK button to not be a default button, I suggest you change its text to something else (e.g. Exit for your case):
okButton.setText("Exit");
How to make enter fire focused buttons
Now, if you also want to make it so that the focused button fires when you press enter, then you can do this:
EventHandler<KeyEvent> fireOnEnter = event -> {
if (KeyCode.ENTER.equals(event.getCode())
&& event.getTarget() instanceof Button) {
((Button) event.getTarget()).fire();
}
};
DialogPane dialogPane = alert.getDialogPane();
dialogPane.getButtonTypes().stream()
.map(dialogPane::lookupButton)
.forEach(button ->
button.addEventHandler(
KeyEvent.KEY_PRESSED,
fireOnEnter
)
);
Note: In any case, focused buttons are always fired when you press space.
We can add ENTER binding to the whole buttons by creating a class that need to be instantiated once when the application starts.
public class EnableButtonEnterKey extends ButtonBehavior<Button> {
public EnableButtonEnterKey() {
super(new Button());
BUTTON_BINDINGS.add(new KeyBinding(ENTER, KEY_PRESSED, "Press"));
BUTTON_BINDINGS.add(new KeyBinding(ENTER, KEY_RELEASED, "Release"));
}
}
When starting the application, call
new EnableButtonEnterKey();
That's it.
I have created the Ui screen named HomeScreen.ui in Qt. This screen have no of different widget like QPushButton, QLabel etc. I want change the default navigation, for that I was trying to capture the keyEvents using keyPressedEvent function
void HomeScreen::keyPressEvent(QKeyEvent *event )
{
int keyCode = event->key();
qDebug() << keyCode;
}
but this is captuting event only when the focus is on homescreen, if the focus is on any child widget like push button keyPressEvent is not getting called. I want to capture event on child widgets so that i can write the navigation for them.
Can anybody tell me how to do that?
I have a TextArea and a Checkbox. I want to disable the SoftKeyboard when the checkbox is checcked, so the TextArea can be scrolled without it popping up. I can get the keyboard to disable when the Checkbox is clicked, but as soon as I click on the TextArea to scroll it pops back up. How do I enable/disable the keyboard with a checkbox? Below is my code:
protected function toggle_keyboard_clickHandler(event:MouseEvent):void
{
checkboxStatus = event.target.selected;
if(checkboxStatus == true){
SoftKeyboardEvent.SOFT_KEYBOARD_DEACTIVATE;
}else{}
}
A SoftKeyboardEvent object is dispatched when a software-driven keyboard is activated or de-activated on a device or operating system. A SoftKeyboardEvent object is dispatched by a TextField or InteractiveObject that has the needsSoftKeyboardproperty set to true.
