Has anyone seen or have an idea on how to go about creating widget that would function like the pop-down message bar here at stackoverflow?
I implemented one with absolute positioning. My entire page is generated by GWT, so it was (relatively) easy to use RootLayoutPanel.get().add(popupWidget), and then use RootLayoutPanel.get().setWidgetTopHeight(), etc, to animate the thing on and off the screen.

I'm building an app with Phonegap/Cordova and Web standards, such as HTML and CSS. However, somewhere on the part of creating this, my skills aren't sufficient.
Ok, let's get this straight: I'm trying to create a navigation bar at the top of the screen. Very basic, even without buttons, just plain text with links.
Check-out this screenshot. As you might see or not.. The middle one isn't exactly placed in the middle. I've tried with div styles, span classes and tables seem the best option.. Yet still insufficient.
What's the best option to create such header?
p.s. No, of course there won't be a border in the table :D - Just for viewing. ^^
I did an example of something like this for a talk... here's a basic version with just a header and some scrollable content: http://jsbin.com/UWeQeli/1/edit
Hope it helps.
I have a project in which I need a way to display essentially a list of tabs, each with their own content pages, down the left side of the page. I'm using TabLayoutPanels elsewhere to good effect, but after looking at how they are constructed it seems like it would be quite a bit of work to undo Google's carefully constructed layout and get it to work in any other orientation than top-aligned.
This doesn't seem like it would be an uncommon layout, so does anyone know of a successful implementation of this kind of container?
Best you can do is use DeckPanel, and make your custom tab controls to switch visible widget in that DeckPanel.
I'm building a GWT app where I want to be able to detect when a user releases a scroll bar on one of my ScrollPanels.
My use case is that the horizontal scroll bar represents time. Since it's impossible to represent the full range of scrollable time I want to just represent a small window of time with the scroll bar. When the user moves and releases the scroll bar I want to do a smooth recentering where the new center is the release point.
I can work out how to do this by building a custom scroll bar widget, but I wanted to check if I was missing some way to do it using a "native" scroll bar first.
You might be able to do it with a ScrollPanel and implementing your own ScrollHandler. Just use the addScrollHandler() method and you should be able to override whatever functionality you need.
However, I would suggest that you re-think your approach. What you seem to really want is a slider control for time, that kind of looks like a scroll bar. You should check out the Composite class and the Widget Gallery to see if there is some combination of Widgets that would suit what you need more. Failing that, I'd also look at SmartGWT. They have a very extensive library of GUI Widgets available, and you may find something you can use already there.
The GWT Incubator contains this widget, but it doesn't provide the clean look and feel I am looking for. The Same page does show precisely the widget I would like to use:
A thin resize bar with the small middle arrow icon which is clicked to hide/show a docked panel on the side of the page.
The widget appears on many google services pages, which makes me suspect that it may be a common widget:
Google Reader
Slightly modified (animated) version on Maps
Does anyone where to find or know how to build this widget in GWT.
How about using a VerticalSpliPanel and overriding the OnClick event? On click you can hide your navigation panel.
I don't think Maps and Google Reader are build using GWT. I know Wave is, and it doesn't use the collapsible panel you're looking for... My guess is that this specific widget is not available in GWT but you may be able to find a suitable replacement. Let me know if you do.
I Am trying to create a Tab Panel where I can add and delete tabs on demand.
Where I am getting stuck is that if a potential user adds too many tabs the new tabs go off the screen.
Each Tab is to contain a text area widget where a user may enter text.
Is there any way of horizontally scrolling the just the TabBar and not the whole browser window?
I could use a scroll panel but I was hoping to scrol just the Tabs, not the panel contents.
I cannot see any available method in the com.google.gwt.user.client.ui.TabPanel API that will perform this function and no real way to split the panel.
Help!
It's not what you've asked for, but you might consider using a StackPanel instead of a TabPanel, since if the user can enter a long list of items it's generally better to have vertical scrolling instead of horizontal scrolling.
The gwt TabPanel isn't the greatest, and there's not a real easy way to do what you want. You could take a look at the tab widget in Ext-GWT, which scrolls the tabs, but I don't think extjs is generally a good idea.
There's a bunch of new layout-based widgets arriving with GWT 2.0. Look at TabLayoutPanel. It places tabs in a very wide container inside a div with overflow=hidden. You might be able to add some controls to scroll that container and get the effect you want.
Good luck, and report back if you get something working. GWT really needs more widget contributors.
