Here's the deal, im trying to create a popup window that uses a dynamic text,
when the text is too large i would like to cap the height of the window and
use a scrollbar instead to navigate through it but it does not seems to be
working.
code:
final Dialog dialog = new Dialog();
dialog.setMessage(direttivaDescription);
dialog.setOverflow(Overflow.AUTO);
dialog.setWidth(600);
dialog.setHeight(50);
dialog.setIcon(someIcon);
dialog.setButtons(new Button("OK"));
dialog.addButtonClickHandler(new ButtonClickHandler() {
public void onButtonClick(ButtonClickEvent event) {
dialog.hide();
}
});
dialog.draw();
If the text is too large the window height will be resized accordingly. The funny
part is that setWidth method seems to be working just fine.
You need a container such as HLayout, VLayout, DynamicForm etc. where you can add the message in it then finally add the container in the Dialog.
Sample code:
VLayout vLayout=new VLayout();
vLayout.addMember(new Label(message));
vLayout.setOverflow(Overflow.AUTO);
vLayout.setWidth100();
...
dialog.addItem(vLayout);
dialog.draw();

I would like to have a customized Dialog styling, having another background color and a rounded border, as it looks nicer than the gray rectangle that comes by default.
This is partially possible, by styling the Contentpane of the Dialog. The problem is, that the underlying Dialog Style is still there, in which the contentpane is shown. And it seems the Dialog UDID itself cannot be changed, nor can the "Dialog" style be overwritten in the designer nor by code.
Form hi = new Form();
hi.getUnselectedStyle().setBgColor(0xffffff);
Button but = new Button("open dialog");
but.addActionListener(e -> {
Dialog d = new Dialog(BoxLayout.y());
d.setUIID("Container"); // this line has no effect, the outside dialog component is still visible
Style s = d.getContentPane().getUnselectedStyle();
s.setBorder(RoundRectBorder.create());
s.setBgColor(0x00ff00);
s.setBgTransparency(255);
s.setMargin(5, 5, 5, 5); // adding some margin between contentpane and Dailog container, to be more obvious
d.setDisposeWhenPointerOutOfBounds(true);
// title
Label title = new Label();
title.setText("Confirmation");
d.add(title);
// body field with spanlabel info text
SpanLabel bodyLabel = new SpanLabel("Body Text");
d.add(bodyLabel);
// delete button
Button okButton = new Button("Ok");
okButton.addActionListener(e2 -> {
d.dispose();
});
// exit button
Button exitButton = new Button("Cancel");
exitButton.addActionListener(e3 -> {
d.dispose();
});
d.add(GridLayout.encloseIn(2, okButton, exitButton));
d.show();
});
hi.add(but);
hi.show();
In above image, the outermost dark gray is the tinted area outside the dialog. The green is the content pane with the intended rounded border. the light grey in between comes from the Dialog style that I would like to get rid off.
Can this be done?
Short answer: setDialogUIID("Container");
However dialogs are a bit problematic to customize via code, I would strongly recommend styling them via the designer/css as we just didn't design them for hand styling and so you're relying on internal implementation details that might break.
When you invoke getContentPane() on the Dialog you're styling the content pane of the Dialog. Not the Dialog itself so the dialog styling still has the non-transparent background. You can use getDialogStyle() to style the Dialog itself. I'm not sure how well that will work.
I want to add close button to top right corner of a dialog box.
I tried using setbounds with addactor and just add and setposition with setsize and addactor, but nothing works. I know that dialog works with table layout, it has a table for content and for buttons. I don't want to use this layout and put the button outside this layout like on the border of the dialog.
How can I do it?
This is how it should be:
The easiest solution I could come up with now, is to use negative padding for your button to move it "outside" of it's cell.
Button closeButton = new TextButton("X", skin, "default");
getTitleTable().add(closeButton).size(60, 40).padRight(-30).padTop(-20);
With this padding hack you have the problem, that the button will be outside of your Dialog, and by default, Window checks the bounds of your window when it performs Actor.hit(...) evaluation.
We need to disable clipping for that reason, but the rendering of the window depends on it. That's why we use another hack to enable it, just for the rendering:
#Override
public void draw(Batch batch, float parentAlpha) {
setClip(true);
super.draw(batch, parentAlpha);
setClip(false);
}
Do this:
private Stage stage;
private Window window;
private Table table;
#Override
public void show() {
table = new Table();
table.setSize(Gdx.graphics.getWidth() / 2
, Gdx.graphics.getHeight() / 5);
window = new Window("", skin);
window.setSize(table.getWidth(), table.getHeight());
Button btnWindow = new Button(skin, "close");
btnWindow.addListener(new ClickListener() {
#Override
public void clicked(InputEvent event, float x, float y) {
window.setVisible(false);
}
});
window.addActor(btnWindow);
btnWindow.setSize(50, 50);
btnWindow.setPosition(window.getWidth() - btnWindow.getWidth()
, window.getHeight() - btnWindow.getHeight());
table.addActor(window);
window.setModal(true);
table.setPosition(Gdx.graphics.getWidth() / 2 - window.getWidth() / 2
, Gdx.graphics.getHeight() / 2 - window.getHeight() / 2 +
100);
window.addAction(Actions.sequence(Actions.alpha(0)
, Actions.fadeIn(.1f)
, Actions.moveTo(+50, +50, 1)));
stage.addActor(table);
}
I had a similar problem. After a bit of searching this thread helped me.
Basically to tell the alignment of the actors inside a table, and to tell the alignment of the table itself are two separate things. Setting the alignment of the table top top-left would produce the desired behavior.
table = new Table();
table.setFillParent(true);
table.setSkin(usedSkin);
table.setDebug(true);
table.top().left();
stage.addActor(table);
table.add(exitBtn);
I have used two scroll bars for controlling brightness and contrast on image after the use i want to reset the scroll bars to their initial value with a button click
I am not getting any links for that to reset scroll bars on button clicks in JavaFX?
The question somewhat unclear. Need explanation of "not getting any links". Some sample code would be helpful. Based on an assumption, try this:
final ScrollBar scrollBar = new ScrollBar();
Button btn = new Button("Reset");
btn.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent event) {
scrollBar.setValue(scrollBar.getMin());
// Or if you have stored initial value somewhere use it
scrollBar.setValue(myInitialValue);
}
});
First of all, I'm a long time Java/Swing developer. I recently installed JavaFX 2.2 to play around with.
I'm creating a fairly simple app, whose main window has a toolbar on top and content in the rest of the window. The obvious way to accomplish this is to use a BorderPane, and stick a ToolBar into the top section. So far, so good. However, I would like some of the controls in the toolbar to be at the left edge of the window, and some at the right edge. I can find no way to do this. I can put an invisible spacer object into the toolbar, but I only know how to give it a fixed width; it doesn't resize when the window is resized.
So I thought that instead of using a ToolBar object, I'll just use an HBox; it should be equivalent to a horizontally-oriented Swing Box object, right? And the Swing Box class has a createHorizontalGlue() method that inserts an auto-sizing spacer. Well, I can't find an equivalent in the JavaFX HBox class. Is there no simple way to do this?
I figured out how to do it using an HBox instead of a ToolBar to hold the controls; the key is the HBox.setHgrow() method, which allows you to set a spacer object to grow to fill the available space. I still don't know if it's possible to do this with an actual ToolBar instance.
/**
* Creates and populates the Node that serves as the window toolbar.
*
* #return a newly constructed and populated toolbar component
*/
private Node makeToolbar() {
// Auto-sizing spacer
Region spacer = new Region();
HBox.setHgrow(spacer, Priority.ALWAYS);
// Horizontal box containing toolbar controls
HBox box = new HBox();
box.setPadding(new Insets(8));
box.setAlignment(Pos.CENTER);
box.getChildren().addAll(openButton, spacer, resizeSlider);
// Colored background panel with drop shadow
Pane bgRect = new Pane();
bgRect.setStyle("-fx-background-color: #e0e0e0;");
bgRect.setEffect(DropShadowBuilder.create().width(1).build());
// StackPane to hold box and rectangle
StackPane stack = new StackPane();
stack.getChildren().addAll(bgRect, box);
return stack;
}
i do it this way:
private Node makeFooter(Node left, Node right) {
ToolBar footer = new ToolBar();
Region spacer = new Region();
HBox.setHgrow(spacer, Priority.ALWAYS);
spacer.setMinWidth(Region.USE_PREF_SIZE);
footer.getItems().addAll(left, spacer, right);
return footer;
}
hope i could help someone
I have a TextField form inside a window. Created with UiBinding. Next to the TextField is a button. I wanted to know if it was possible to create a new TextField widget when that button was pressed using UiBinder?
This is what I have:
Window class:
#UiField
TextField text;
#UiField
HorizontalPanel hPanel;
....
#UiHandler("addText")
public void onClick(SelectEvent event){
hPanel.add(text);
}
My UiBinder file:
<gxt:Window ...(generic setup)...>
<g:VerticalPanel>
<gxt:FramedPanel>
<container:VericalLayoutContainer>
<container:child>
<g:HorizontalPanel ui:field="hPanel">
<form:FieldLabel text="Text">
<form:Widget>
<form:TextField ui:field="text"/>
</form:Widget>
</form:FieldLabel>
<button:TextButton ui:field="addText"/>
</g:HorizontalPanel>
</container:child>
</container:VericalLayoutContainer>
</gxt:FramedPanel>
</g:VerticalPanel>
</gxt:Window>
When I click the button it all it does is move the button from the right side of the text field to the left. I have more textfields in the window so I played around to see what it was really doing. It's taking that field and just moving it next to the button.
Is there a way I can create a new TextField underneath the original?
Probably LazyDomElement will help you.
