Get slidingpanellayout events

I'm using sliding panels with my android app, but i need to get an event when the panel is up, is there a way listen to when it happens?
im using a sothree Sliding panel library

Looks like you are talking about umano/AndroidSlidingUpPanel. After briefly looking at the documentation/code you should be able to set a PanelSlideListener to your SlidingUpPanelLayout. They also provide a SimplePanelSlideListener which inserts no-ops for any functions you choose not to implement, which is probably what you will want to use.
For example inside of your Activity's onCreate you could do something like:
SlidingUpPanelLayout slidingPanel = (SlidingUpPanelLayout)findViewById(R.id.your_sliding_layout);
slidingPanel.setPanelSlideListener(new SimplePanelSlideListener() {
#Override
public void onPanelExpanded(View panel) {
// Insert your code here
}
});

Vaadin 7 - update textarea at value changed

I'm new at vaadin and I want to display some infologs in a textarea. Currently I have set the pushmode in my CustomComponent to PushMode.AUTOMATIC ( #Push(PushMode.AUTOMATIC) ). But this works only the first time. To refresh the text I have to resize the window manual or click a button.
I found something called ICEPush but I do not understand this stuff :( and do not found good tutorials...
Has anybody a hint for me?
Thanks for help!

have you made sure you changed the TextArea value using the ui.access method, and called the ui.push() method?
Kind of like this:
ui.access(new Runnable() {
#Override
public void run() {
textArea.setValue(newValue);
ui.push();
}
});

How can I detect that a menu is open in JavaFX?

I'm writing a JavaFX app and have a menubar with partial transparency. When the user mouses over the menubar, it becomes fully opaque. I'd also like it to be opaque when the user has opened one of the menus. Is this possible somehow? I'm using JavaFX 2 if it matters.
Thanks.

try this..!!
menu.setOnShowing(new EventHandler<Event>() {
#Override
public void handle(Event t)
menubar.setStyle("-fx-background-color:transparent"); //
// or you can use set opacity property
menubar.setOpacity(0.25);
}
});
this event occurs when you show you menu...there also menu hidden propety..you can also use it.

JLabel does not update when using setText method

In the project I am currently working on I have several pieces of information that I would like to make visible via Jlabel. There are a few buttons and textfields elsewhere in the GUI that allow for altering said information I would like to update the JLabel but the text never changes, or updates upon startup.
I have attempted to use concurrency to update the labels, as suggested in other questions on this site, but I have had no luck with the labels updating. The concurrency does work with updating textfields and comboBoxes as needed.
The current iteration of my code looks as follows,
The JFrame
//// This is a snippet from the JFrame
public void start()
{
this.setSize(900, 700);
this.setVisible(true);
devicePanel.populateDeviceDefinitions();
updateServiceInfo();
updateCommandInfo();
startUpdateTimer();
}
public void updateServiceInfo()
{
EventService service = JetstreamApp.getService();
generalPanel.updateServiceInfo(service.getBaseUri(),
service.getAccessKey(), String.valueOf(service.getWindowTime()));
}
public void updateCommandInfo()
{
JetstreamServiceClient client = JetstreamApp.getClient();
generalPanel.updateCommandInfo(client.getBaseUri(), client.getAccessKey());
}
The JPanel named generalPanel
//// This is a snippet from the generalPanel
//// All of the variables in the following code are JLabels
public void updateServiceInfo(String baseUrl, String accessKey,
String windowTime)
{
serviceUrl.setText(baseUrl);
serviceAccessKey.setText(accessKey);
serviceWindowTime.setText(windowTime);
}
public void updateCommandInfo(String baseUrl, String accessKey)
{
commandUrl.setText(baseUrl);
commandAccessKey.setText(accessKey);
}
The labels start with an Empty string for their text and upon window start it is intended that they be updated by grabbing the information from the relevant sources. Can I please have some insight as to why the JLabels never update and display their information?

How did you create the JLabel? If the text starts out as "", and you've created it with new JLabel(""), the width of the JLabel may be initialized to 0 and then none of your text would show up when you update it. I believe I've had that sort of problem in the past. As a test, try using new JLabel("aaaaaaaaaa") or some longer string to create the label, then setText(""); then later, when you setText(somethingElse), see if that causes text to show up. If it does, then the width is probably the problem and you can work on it from there. – ajb 19 mins ago
This comment is the actual answer, when creating a JLabel with an empty string as the text the label's dimensions do not get set properly when using WindowBuilderPro. My labels did exist, and were being updated with the code provided in my question but the labels were not visible.
Starting with a label that has text in it, then setting the text to an empty string works properly.

The method paintImmediately() can be used to cause a Swing component to get updated immediately. after setText(), you should call paintImmediately() like below.
jLabel.setText("new text")
jLabel.paintImmediately(jLabel.getVisibleRect());

You should try to call revalidate() or repaint() on the component that contains your JLabels.

SWT, Maintain default tab ordering when adding Key Listner

I've been creating a custom TabFolder extension that adds a key listener to allow quick tab switching using an ALT + # hotkey.
By adding the KeyAdapter to my TabFolder, the event handler works properly only when you have a tab header selected (in which case the ALT + ARROW_LEFT/ARROW_RIGHT also work.). I need this hot key to be active when any Widget with-in the TabFolder is active; however, it shouldn't be active if the selection is in a different tab folder or widget outside of a tab folder.
In an attempt to solve this, I wrote a simple recursive function to apply the key listener to all of the children of the tab folder:
public void applyQuickSwitchKeyBindings() {
removeKeyListener(ka);
addKeyListener(ka);
for(Control c: getChildren())
applyQuickSwitchKeyBindingsToChildren(c);
}
private void applyQuickSwitchKeyBindingsToChildren(Control c) {
if(c==null) return;
if(c instanceof Composite) {
Control[] controls = ((Composite)c).getChildren();
for(Control c2: controls)
applyQuickSwitchKeyBindingsToChildren(c2);
if(controls.length < 1) {
c.removeKeyListener(ka);
c.addKeyListener(ka);
}
}
}
Then i call the applyQuickSwitchKeyBindings() after I add the controls to each TabItem in the tab group.
The good news was that the quick switch hot key (ALT + #) worked great!
The bad news was that the original TAB ordering based on z-index is now gone. When you hit the SWT.TAB key you lose focus on your current text box and don't gain focus on anything else...
Questions:
1.) Can each control only have one KeyListener?
2.) Why is the original TAB traversal not working anymore?
Thanks in advance!

to 1) I'm pretty sure that more than one KeyListener is allowed.
to 2) I'm not sure, that depends on what you're doing in your KeyAdapter. Maybe you can post that too?
I just the tab order is broken somehow, you can reset ( or change ) it with a call to setTabList( Control[] ).
setTablList( new Control[] {
control1,
control2,
control3,
....
} );

So after more time learning and developing with SWT i've discovered my problem. When you add a listener it is applied to the widget/control you call the addXXXListener function on. So if that control is not active the listeners will not be fired.
The solution seems to be SWT's global Filter mechanism which allows you to add global application(Display) scope listeners.
Display.getCurrent().addFilter(SWT.keyPress, new KeyPressListener());
Pardon the incorrectness of this line, but if you google it you'll see what i mean.
I have also read to use this sparingly.
