Hi there.

Some weeks ago, I found some examples on the web, showing how to create
websites with RAP, but hiding RAP (startingin fullscreen, theming, etc.).

Does anyone know, where to find these pages? I've searched google,
www.innoopract.com and www.eclipse.org/rap several times, but I can't
find the sites.

Greets.

Hi Alex,

what exactly do you want to do? Hiding the bar of the main shell and the
menu bar can be achieved by some lines of code in your implementation of the
WorkbenchWindowAdvisor.

@Override
public void preWindowOpen() {
IWorkbenchWindowConfigurer configurer = getWindowConfigurer();

// Hide shell title bar
configurer.setShellStyle(SWT.NONE);
configurer.setShowStatusLine(false);
configurer.setShowMenuBar(false);
}

@Override
public void postWindowOpen(){
IWorkbenchWindowConfigurer configurer = getWindowConfigurer();

// set maximum shell bounds to current size of display (maximizes
main window)
configurer.getWindow().getShell().setMaximized(true);
}


For theming, take a look at the RAP wiki:
http://wiki.eclipse.org/RAP_Theming

Regards,
Stefan.

Thanks for this very detailed explanation, but I'm only looking for this
example webpages.

I'll come back to your code snippets and the theming later, 'cause I
first want to demonstrate the pages to those, who are intrested in the
rap technology.

Hi Alex,

i think you're talking about www.eclipsediscovery.org

Just a few days ago we deployed another sample application with a web
look&feel at http://rap.eclipse.org/rapdemo/rms

Hi,

not sure which application you mean. The actionbar advisor of
eclipsediscovery is implemented similar to the snippet available here:

http://dev.eclipse.org/newslists/news.eclipse.technology.rap /msg00794.html

The new demo's source isn't available yet. But we plan to publish the source
in the sandbox module of the CVS soon.The demo application does nothing
unusual in the actionbar advisor, but there is one little hack in the
postWindowOpen() method of the WorkbenchWindowAdvisor to place the banner
between toolbar and workbench page on the main perspective. We cast the
IWorkbenchPage to the internal type WorkbenchPage (ugly, ugly - I know) to
get access to the client composite of the page.

WorkbenchPage wPage = (
WorkbenchPage )getWindowConfigurer().getWindow().getActivePage();
Composite clientComposite = wPage.getClientComposite();

After that we are able to use a control listener to react on resizes of the
shell for example to readjust the page. The banner is made of some simple
labels with images parented to the shell.

Ciao

I meant the new demo's source. I also needed an area to show a banner, but
not only for specific perspective. I've ovewritten
WorkbenchWindowAdvisor#createWindowContents to place a banner beetween the
menu bar and the toolbar.

I tried it some weeks ago and I failed because of my inexistent knowledge
about FormLayout, but yesterday I tried it another time and I was successful
:-)

Hi,

the date picker of the demo is very interesting, in fact i'm in desperate
need of such a widget. unfortunately i'm not into javascript to create
such a custom widget by myself. maybe there is a description of how to
create this widget for "beginners"?? :))

hello,
You can try to create the widget by GWT, translate him in javacsript by
the gwt complier and use GWTWanted to encapsulate the javascript into a
web page...

Hi,

for the java-side of life err..of RAP you need to implement the widget
on the server-side. See
http://help.eclipse.org/help33/topic/org.eclipse.rap.help/he lp/html/advanced/custom-widget.html
for help. The javascript side which is just a thin presentation could be
a 3rd party javascript calendar (try google, you'll find hundreds of them).

Hi,

here comes the code for the date-picker of the RAP Workbench Demo. It's
build only using already existing SWT stuff. I didn't have the time to
create a fancy javascript based custom component so I used
http://www.java2s.com/Code/Java/SWT-JFace-Eclipse/SWTCalenda r.htm as an
inspiration. So surely the implementation could have been nicer and a custom
component should be faster, but it works...

The second class is just for single sourcing, since I also have an RCP
version of the demo, but that's still work in process. So if you like to use
the date picker you can also inline the class completely.

I'm trying to use this DatePickerDialog in my application, but the
LifeCycleLock and LifeCycleControl classes are unavailable. What plug-in
do I need to add to my dependencies to have them included in my classpath?

Hi Alexandros,

i'm using this datepicker in my apps and i advanced it a little.
i updated the code to work with the current rap release (removed lifecycle stuff
an added readAndDispatch), moreover i added calendarweeks.

in your programm you just open this datepicker like a usual dialog (open()). it
returns a string of the selected date. here is the source code. hope it helps!
feel free to ask if there are problems.

Hello Ben,

Thank you for the date picker.

With your code as a basis, I have created a "widget" version so that one
can use it in dialogs and forms (I like putting these in expandable
composites / sections of forms).

I thought I'd share it in the spirit of OSS. I found several related
posts in the newsgroup while looking for a date picker and this thread
seems to be the most informative.

Thanks again,
Cheers!

Hello,

For the convenience of others, I thought that I would share my simple
DatePicker Composite that uses the previously posted calendar dialog.

Hi all,

in the meantime there's a DataTime widget available in RWT. This should
ease the task of implementing a datepicker dialog.


Ciao
