I want to have a menu for my program. And I like the standard Menu look and all, but I want to place a "logout-button" on the far right side of the menu-bar.. is it possible to place it there WITHOUT having to fill up the whole menu-bar with entries?
Sincerely
Yes you can. Use the HBox#setHgrow();. This javadoc page also has an example how to use it in "Optional Layout Constraints" section. Following is taken from javadoc.
For example, if an hbox needs the TextField to be allocated all extra space:
HBox hbox = new HBox();
TextField field = new TextField();
HBox.setHgrow(field, Priority.ALWAYS);
hbox.getChildren().addAll(new Label("Search:"), field, new Button("Go"));
Briefly speaking, set Priority.ALWAYS for the button (or any control) just before the "logout-button" in a HBox. More advanced example is here: Using Built-In Layout Panes : Example 1-4

i am making a java desktop application using javafx. For gui building i am using scene builder 2.0.
Everything is just perfect as expected just 1 thing. I want to customize the buttons. i want to assign a custom graphic to a button.
When i use [button.setgraphic(node)] , this statement set the new graphic to the button but default graphic of button also remains present as well.
I just want to remove the default graphic and then want to assign the new (custom) garaphic to a control like buttons and radio buttons in javafx. 1 thing again i must tell that i am using scene builder for building gui.
How can i achieve this ?
thanks in advance....
Below is the screen-shot of current occuring situation, .....
Here i have made a button using javafx scene builder , and then in the controller of the fxml file (.java file) i am trying to set the image (shown in orange box in snapshot) to that button by using setGraphics property of button ..... i just need that button to be of following shape ...
You'd better customize your button via CSS. Here goes tutorial. What you are trying to do is to modify button picture (which is empty by default). I guess this wasn't your exact purpose.
button.setGraphic(null)
// worked for me.
I have a couple of buttons and want to collect them in a HBox and set them in a vertical row. The goal is something similar to this formation: http://vandelaydesign.com/images/navi/vertical.gif
Button addButton = new Button("Add Expense");
addButton.setOnAction(new AddExpenseGUI(rootStage, data));
Button editButton = new Button("Edit");
addButton.setOnAction(new EditButtonListener());
I tried multiple things. This was one idea of me, but I just get a horizontal formation:
HBox a = new HBox();
a.getChildren().addALL(addButton, editButton);
grid.add(a,0,0);
Any ideas?
Use a VBox and skin your buttons. See these:
Skinning JavaFX Applications with CSS
Styling FX Buttons with CSS
The H in HBox stands for Horizontal so the Pane you are looking for is VBox (for Vertical)

I am working on an App in which I have an icon on Action Bar.When I click on this Action Bar icon then an EditText should come on the top of layout(below Action Bar) and all of the other data on layout should shif down.I am using Relative Layout.
I know how we can dynamically add view in relative layout.But here I have to add item on top on layout, while there is also some view on top before clicking the icon.
Try the below if it works for you, this is what you'll need as per my understanding of your question.
EditText et = new EditText(this);
empty.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
et.setText("Dynamic EditText!");
et.setMinLines(1);
et.setMaxLines(3);
relativelayout.addView(et);
// assuming you already have your relative layout and the rest declared.
I want to place the components A and B over component with List. I need that would text of list will be to visible. I can not find which layout can do it.
How this behavior is in lwuit? What solutions exist?
The question is somewhat unclear, jmunoz answer is correct if you want component's A and B to reside at the bottom of the screen and the list to scroll above. However from the drawing it seems you want an "always on top" effect which you can achieve either via a glass pane (for non-interactive components) or via the LayeredLayout class.
This is actually quite simple using the following:
myForm.setLayout(new LayeredLayout());
myForm.setScrollable(false);
// will occupy the entire area of the form but should be scrollable
myForm.addComponent(componentUnderneath);
Container south = new Container(new BorderLayout());
myForm.addComponent(south);
south.addComponent(BorderLayout.SOUTH, whateverYouWantToPlaceOnTopInTheSouth);
You must do the following:
The Form must not do scroll. Use Form.setScrollable(false). Set the layout of the ´Form´ to BORDER_LAYOUT, myForm.setLayout(new BorderLayout()) . Ok in BorderLayoutyou can put the components in the Form as you want.
Put the Listcomponent in the center of the BorderLayout with myForm.addComponent(BorderLayout.CENTER, List) and the other two elements in the south of the layout using
Container southContainer = new Container();
southContainer.addComponent(A);
southContainer.addComponent(B);
myForm.addComponent(BorderLayout.SOUTH, southContainer)
With this you can get a scrollable Listand two elements always visible.
I have a scroll view, and when a user moves from one imageview to the next, I want the title in the navigation bar to change. So I want to set a new title for the navigation bar for each image in the scroll view. How would I go about doing this?
Thank you very much for your help.
Write a delegate for your scroll view. In the delegate, implement the scrollViewDidScroll: method to figure out which image is currently visible and change the title.
To eliminate your incompatible type warning, you can declare that ScrollViewController adopts the UIScrollViewDelegate protocol:
#interface ScrollViewController : UIViewController <UIScrollViewDelegate>
