GXT Attached / Rendered - gxt

I have a GXT ContentPanel instance (cp). I attempt to add a Text object to the content panel as below:
Text text = new Text("Main Content Window");
cp.add(text);
However, the Text is not visible even though I did text.setVisible(true). In my debugger, I saw that the content panel (cp) does have the text object added to the cp.items list. However, the text object has "rendered = false" and "attached = false".
Thanks for Help!

you may add the text to ContentPanel using Label which is straight forward.
by the way text is not not component to add to the panel(Contentpanel/ layout container)
we can add only component to the container.

If ContentPanel is already rendered and you add anything to it you have to call cp.layout() to add new contents to the DOM. If you add the text before rendering it it's not necessary.

Collapsible accordion not showing content when initialized collapsed

I'm using twitter bootstrap with JSF-2.2.4 and Spring 3.2.4 Framework. I've built a collapsible accordion based on the following tutorial: http://getbootstrap.com/javascript/#collapse
The code seems to work fine, but only if I start with opened accordions, meaning that I add the 'in' class to the div which inherits the content which is supposed to be collapsed. If I remove the 'in' class the accordion is opened by clicking the appropriate link, but the content is no displayed.
Content is plot created with plotfaces.
Any ideas?
Edit: I just tried filling the box with an image. This seems to work. Maybe this helps narrowing down the problem.
I don't know how this plotfaces work, but i expect your problem similair to fullcalendar not visible until button is clicked or window resized?
Try to set .collapse {display;block; visibilty:hidden;} instead of display none. If this don't helps try to focus on the height of the element. The plugin change the height from 0 to auto but on initial load the height is not set.

How to add an view on top on activity layout dynamically which automatically shifted the old view down

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.

how to set lwuit textarea scrolling false

I want to add large string content to a container dynamically.
There are 60 different contents(strings) to be displayed in this container.
To add the string to container, I am adding a TextArea(empty border with 100% transparency).
The problem is that TextArea offers scroll and I do not want it to scroll. Instead I want to grow(increase height) according to content. I am unable to achieve this.
Can you help me out with this?
Or can I use any other component for the purpose?
I am using LWUIT with J2ME.
You can derive text area and return false for isScrollableY() although it should generally work seamlessly even if you don't do that (since your parent layout is scrollable). Is it possible you changed the text area and don't revalidate the parent form on the EDT?
There are problems with text area layout when it is modified by a separate thread (race condition with the layout code).
First put the TextArea.setSingleLineTextArea(false) , and grow by content true.

javafx 2.0 TitledPane how to change the title text to image+text

the default title only contains text, just like the "Apples" title in the above image.
is that possible to add image in the title.
or
is there a way developer can build a customized TitledPane ?
thanks
Use setGraphic method
TitledPane tp = new TitledPane("hi");
tp.setGraphic(new Rectangle(10, 10));
As far as I know, you can set the graphics via the css property "-fx-graphic" as well.
See Oracle Defintion for JFX and CSS, here for elements of type Labeled.
To remove the button completely, you could either
set tp.setCollabsible(false); or
use the .titled-pane CSS class to set the property "-fx-collapsible" to false.
See Here (same side as above, but for TitledPane).

LWUIT, How to create a custom label for form title

I want to know how to create a label that contains two icons, one on each side and set it as the title bar for the form element (LWUIT widgets).
Form has a function to get a titleArea then you can put some components what you want.
Form f = new Form();
Container c = f.getTitleArea();
Label iconLabel1 = new Label("leftIcon");//using Image
Label iconLabel2 = new Label("rightIcon");//using Image
c.addComponent(BorderLayout.WEST, iconLabel1);
c.addComponent(BorderLayout.EAST, iconLabel2);
You can just add a component to the north portion of the screen which is the recommended way that will work properly and won't break for newer versions of LWUIT/Codename One.
When you don't set a title it will just work and you can give it the Title UIID. LWUIT 1.5 and newer have a TitleArea container but I suggest you stay away from it since CodenameOne customizes it quite allot for iOS/Android 4.x etc.
Use the setTitleComponent(Label title) method.
EDIT :
Derive the Label class and implement the paint method where you can use the Graphics method to draw Images and texts. Also set the label's text position to Label.CENTER .
