I am having some problems trying to style a monotouch.dialog.
I am setting the background dialog like
public override void LoadView ()
{
base.LoadView ();
TableView.BackgroundView = null;
TableView.BackgroundColor = UIColor.FromPatternImage(UIImage.FromBundle("Images/Background/bg-app"));
The section title looks ok however each of the elements looks like its recreating the background.
What is the easiest (and best) way to only display the white frame and not to recreate the background? I want the look of a single background image with the dialog appearing over the background
You can try setting an image the full size of the table view -
TableView.BackgroundView = new UIImageView(UIImage.FromFile("image-size-of-table-view.png"));

I'm developing an application using GWT 2.3.0 and GXT 2.2.5.
I've got a LayoutContainer with ScrollMode set to AUTO and layout set to RowLayout with a horizontal orientation. It's used as the display window for my application.
The problem is that when the browser is resized so that the vertical scrollbar is displayed, the contents do not resize to account for it, causing the horizontal scrollbar to also appear even if it's not needed.
Is there a way to have the layout account for the space taken up by the scrollbar when rendering the widgets?
Ok that is a bit tricky to accomplise. I would do it like this:
On the Entry point (so that you know it is always active) add a resize handler to the Window
Window.addResizeHandler(new ResizeHandler() {
#Override
public void onResize(ResizeEvent event) {
// Fire Event containing the new size informing the application of the change
// Or resize the Layout container
}
}
If you choose to fire the event and you are using the MVP pattern then it is pretty simple to fire the event via the event bus and catch it wherever you like in the application.
The only catch here is that you might want to run the functions in onResize() inside a timer as in many cases the Window width/height reported have not the final value, due to the event being fired before the resizing completes.
I need to handle multiple panels, containing variuous data masks. Each panel shall be visible using a TreeView control.
At this time, I handle the panels visibility manually, by making the selected one visible and bring it on top.
Actually this is not much confortable, especially in the UI designer, since when I add a brand new panel I have to resize every panel and then design it...
A good solution would be using a TabControl, and each panel is contained in a TabPage. But I cannot find any way to hide the TabControl buttons, since I already have a TreeView for selecting items.
Another solution would be an ipotethic "StackPanelControl", where the Panels are arranged using a stack, but I couldn't find it anywhere.
What's the best solution to handle this kind of UI?
You need a wee bit of Win32 API magic. The tab control sends the TCM_ADJUSTRECT message to allow the app to adjust the tab size. Add a new class to your project and paste the code shown below. Compile. Drop the new control from the top of the toolbox onto your form.
You'll get the tabs at design time so you can easily switch between pages. The tabs are hidden at runtime, use the SelectedIndex or SelectedTab property to switch between "views".
using System;
using System.Windows.Forms;
class StackPanel : TabControl {
protected override void WndProc(ref Message m) {
// Hide tabs by trapping the TCM_ADJUSTRECT message
if (m.Msg == 0x1328 && !DesignMode) m.Result = (IntPtr)1;
else base.WndProc(ref m);
}
}
A good solution would be using a TabControl, and each panel is contained in a TabPage.
But I cannot find any way to hide the TabControl buttons, since I already have a
TreeView for selecting items.
For the above,
You need to set the following properties of TabControl.
tabControl.Multiline = true;
tabControl.Appearance = TabAppearance.Buttons;
tabControl.ItemSize = new System.Drawing.Size(0, 1);
tabControl.SizeMode = TabSizeMode.Fixed;
tabControl.TabStop = false;
I want to create a JavaFX table that, in the cells of one column, allows the user to edit XHTML text. I only need very basic formatting capabilities like bold, italic, striketrough.
I have already managed to implement this by using my own subclass of TableCell and using a WebView for each cell (HTMLEditor would of course have been another choice, but my guess is that for my requirements, WebView should be sufficient).
However, to make editing comfortable for the user, I need the following features:
1. The cell height needs to resize if the user enters multi-line text.
2. A context menu (or, if not possible, some other menu or button) should allow formatting parts of the text in a cell as described above (bold, italic..)
Has anybody been successful in implementing something similar ? I have seen suggestions on the web, but they rarely included code samples.
I have succedded doing something similar.
I figured I can share some of the basic clues that allowed me to achieve it.
Resize the whole WebView. For that, the whole WebView must be an editable html page. You achive that by setting contenteditable to true:
<body contenteditable='true' id='content'></body>
You can have a context menu over a webview. But it is something tricky, as you must first disable the original context menu associated to it.
WebView editView;
...
EventDispatcher originalDispatcher = editView.getEventDispatcher();
editView.setEventDispatcher(new WebmenuEventDispatcher(originalDispatcher));
And this is the event dispatcher class:
public class WebmenuEventDispatcher implements EventDispatcher {
private EventDispatcher originalDispatcher;
public WebmenuEventDispatcher(EventDispatcher originalDispatcher) {
this.originalDispatcher = originalDispatcher;
}
#Override
public Event dispatchEvent(Event event, EventDispatchChain tail) {
if (event instanceof MouseEvent) {
MouseEvent mouseEvent = (MouseEvent) event;
if (MouseButton.SECONDARY == mouseEvent.getButton()) {
mouseEvent.consume();
// Show our own menu
cmEdit.show(editView.getScene().getWindow(), mouseEvent.getScreenX(), mouseEvent.getScreenY());
}
}
return originalDispatcher.dispatchEvent(event, tail);
}
}
Now, for setting the font from within that menu, you need a bidirectional Java<->javascript bridge and use some javascript in the webview side.
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.
I am trying to do this:
public class DialogMenuHawaii extends Dialog {
Style s = UiFactory.getBaseStyle();
s.setBgTransparency(0);
s.setBgImage( <my image >);
this.setUnselectedStyle(s);
}
but it doesn't work.
First, I suggest you use a theme. We constantly change small implementation details e.g. customizations like the one you are doing will not be portable between LWUIT 1.4 and 1.5. There is no reason whatsoever not to use a theme for something like this.
If you are interested in the pain and suffering of manually coding view logic into your application you can use several methods such as getDialogComponent() to get the style from them and manipulate that. Dialog is a complex beast due to the fact that its really a form padded away from the edges.
Open your '.res' file in resource Editor and select your preferred theme,
Under 'Unselected' tab open the DialogContentPane style, if you don't have one create it look at the end of this answer on HOW TO DO IT?, and set the background image to the image you need to show as Dialog bg
Under 'Unselected' tab open the DialogBody style, if you don't have one create it look at the end of this answer on HOW TO DO IT?, and set the background transparency as '0' and also make sure the background image type is NONE
NOTE: The above code will reflect for all the Dialogs in your application. If you want a particular dialog with background image than derive new styles from these default styles, and follow the above steps to apply it to your DialogMenuHawaii or any runtime Dialogs.
HOW TO: I would recommend you to go through the Shai's blog posts LWUIT Resource Editor Tutorial Part 1 till part 10. To better understand the Resouce Editor its features and capabilities.

PS: Programmatic-ally i haven't been able to achieve it using TextArea which is the case for default Dialog's. If you replace the dialog body component with Label if works fine, the code sample is given below. I haven't delved much into why is it so ? maybe will do it in my free time. Hence i have proposed a working alternative solution which is scripted above using Resource Editor and below using the code
class MyDialog extends Dialog {
public void show() {
Container octnPane = this.getDialogComponent();
octnPane.getUnselectedStyle().setBgTransparency(0, false);
Container ctnPane = (Container)((BorderLayout)octnPane.getLayout()).getCenter();
ctnPane.getUnselectedStyle().setBackgroundType(Style.BACKGROUND_IMAGE_SCALED, false);
ctnPane.getUnselectedStyle().setBgImage(myImage, false);
Label t = new Label("Dialog");
t.setUIID("DialogBody");
t.getUnselectedStyle().setBgTransparency(0, false);
ctnPane.addComponent(t);
super.show();
}
}
This is for Dialog background.
Dialog dialog = new Dialog();
dialog.getDialogStyle().setBgImage(Image.createImage("/image/image.png"));
If you want to set transparency of Dialog with image.
dialog.getStyle().setBgImage(Image.createImage("/image/image.png");
