Re: Image from resource in SafeHtmlTemplate
You can use the following code to build the html for the image:
AbstractImagePrototype.create(Resources.Singleton.GetMyImage()).getHTML();

When I call MyTemplates.GenerateCellHtml an exception is thrown because the

Is it possible to use SafeHtmlTemplates with an Image sourced from a

Re: Image from resource in SafeHtmlTemplate
You don't have to run the result of AbstractImagePrototype.create
through the template, just add it to the SafeHtmlBuilder:
String imageHtml =
AbstractImagePrototype.create(Resources.sSingleton.getMyImage()).getHTML();
safeHtmlBuilder.appendHtmlConstant(imageHtml);

Re: GWT CELLTABLE How to restore old value in cell if validation fails
No, I don't think that's possible.
But you can store all your edit cells in a list and clear them all at
once, like this:
// when setting up table columns add the edit cells to this list
ListEditTextCell editCells = new ArrayListEditTextCell();
// clear incorrect values for the whole row
for (EditTextCell editCell : editCells)
{
editCell.clearViewData(KEY_PROVIDER.getKey(object));
}
cellTable.redraw();

Re: Web-/Server Management Tool with GWT
Hi any, Pretty big project to start with :). I think you're looking at it wrong as the main task will be to handle all the configuration for the server services, and GWT can only provide the user interface. All the background server work has to happen on the server, and GWT only runs on the client. First you should decide what to use on the server side, then decide what to use for the client. Also I think you're trying to reimplement the wheel, there are a lot of projects that already do some of the things you want. You should check out: - Zentyal (http://www.zentyal.org/) - nice gui for server management on Ubuntu - Sme Server (http://wiki.contribs.org/Main_Page) - same for CentOS - there are others but these two I have used. There are a lot on man years spent on developing these projects, and as they are open source you can contribute / branch them.

I mean, the user would safe his credentials to the database and then, each time, he logs in to the tool, he will be also authenticated to HEX and he can access his E-Mails from the tool (without the need of loading/authenticating another Website). I know, saving these credentials to the database isn't really secure (maybe there are more secure ways to do this). -- Server Status: in this module I'd like to see different information about the (Debian-)server, the tool is running on (like CPU load, available memory, running services).

Re: CellTable with SimplePager displaying GAE datastore data in async
What framework are you using to connect to the datastore? I've not used JDO or JPA, but in Objectify you can set an offset and a limit on a query. In onRangeChanged you can get them like this: Range range = display.getVisibleRange(); Integer offset = range.getStart(); Integer limit = range.getLength(); So there's no need to work with cursors. If this functionality is not exposed through your datastore layer you could always use the low level api.

Everything works fine up to the last page. So if pageSize is 10 and the results are 35, doing 1-10, 11-20, 21-30 and back works fine. In order to do this I store cursors so that I can continue from where I left off or go back. If however, I go to the last page and the range changes to display 25-35 and then back like so, 35-25, 25-15, 15-5 etc the cursors are rendered useless. Have you comes across this problem? What are your experiences? Maybe I am not using SimplePager properly?

Re: problems using ScrollPanel and layout panels
Williame, thanks for your response, I really hope we can find an
elegant solution.
I don't think that your approach works well for dynamic content. I
don't really know the size of the cell tree in advance so I can't
adjust the size of the containing panel when placing the cell tree in
it.
At first, I used like you a HtmlPanel as my main container, and I had
outside scrolling working fine, but I had to switch from it when I
started to use a SplitLayoutPanel for one of my views, because the
split panel worked only when specifying the exact height for it, I
couldn't get it to work with a height of 100%.
So I switched to using RootLayoutPanel and converted all my outer
panels to layout panels and the SplitLayoutPanel started to work
correctly (not surprisingly, as the documentation for layout panels
clearly says that you have to attach them only to other layout
panels). Having solved that I bumped into this inner scrolling
problem.
From the layout panels documentation:
ScrollPanel... works well in layout panels (see below), which provide
it with the explicit size it needs to scroll properly.
And below we have this example:
g:DockLayoutPanel unit='EM'
g:north size='4'
g:LabelHeader/g:Label
/g:north
g:west size='16'
g:LabelNavigation/g:Label
/g:west
g:center
g:ScrollPanel
g:LabelContent Area/g:Label
/g:ScrollPanel
/g:center
/g:DockLayoutPanel
Which is like my code, except they use static content for the scroll
panel.
I suppose an elegant solution must exist, because almost all web apps
will use dynamic content.
On Jul 3, 4:22 am, Williame william.eub...@uah.edu wrote:
I feel your pain. I've spent hours trying to make my center docklayoutpanel
scrollable while at the same time make it replacable by new widgets based on
menu choices. Most things worked fine by putting a Scrollpanel in the
center block, except TabLayoutPanel put a few level inside it would never
show the tab headers. I found that ResizeLayoutPanel can help. Hope it
never gets deprecated.
You can use Window.getClientWidth() and Window.getclientHeight() to get the
visible window size in pixel, then subtract the size of the other screen
elements. But this did not resize well for me and I did not want to write a
lot of code to handle and propagate onResize.
In the end I went with an html panel for my main outer interface, so I could
use simple div elements for the top(north) elements, and used a
ResizeLayoutPanel for the placeholder for content. In the java side of the
uibinder code I put in a call to a ResizeLayoutPanel size adjustment after
clearing and placing new panels into the ResizeLayoutPanel widget.
g:HTMLPanel styleName={style.mainPanel}
div class={style.header}My Company name/div
div ...
!-- content widget placeholder --
g:ResizeLayoutPanel ui:field=uberContent title=Content
styleName={style.appcontent} height=384px width=681px/
/g:HTMLPanel
In the code to replace the content widget with a different widget, the panel
size of the new widget can be used to resize the placeholder widget if the
new panel is a fixed size layout panel. If it is not, you need to
explicitly specify the size of the new panel:
uberContent.clear()
MyPanel panel = new MyPanel();
uberContent.add(panel);
adjustContent(panel.getOffsetHeight(),panel.getOffsetWidth());
In adjustContent(int height, int width) method, reset placeholder widget
size to just a little bigger than the new panel added to it:
uberContent.setHeight(height + 50 + px);
uberContent.setWidth(width + 20 + px);
The css for the placeholder widget, uberContent, sets margin-bottom to keep
the panel below the header div's. The scrolling seems to work like a normal
web app, resizes work pretty well too. Tested with latest of each: IE,
firefox, chrome, safari and opera. Even iPad(safari). The overflow css
attribute seems to wreak havok on layout panels, especially tablayoutpanel.
I have it set to overflow: scroll; for the style.mainpanel, outer
htmlpanel. But not set at all for the ResizeLayoutPanel style.
DockLayoutpanel sets overflow: hidden by design.
I wouldn't be surprised if there are several better, more elegant solutions,
which I would love to know of, but this worked for me. Hope it helps.
Discalimer I am neither java, css or gwt expert. But do love gwt. Thank
you Google!! /Disclaimer

problems using ScrollPanel and layout panels
Hi all, I have the following code: g:DockLayoutPanel unit='PX' ui:field=dockPanel g:north size='35' g:HTMLPanel Header /g:HTMLPanel /g:north g:center g:ScrollPanel width = 100% height = 100% p1:CellTree ui:field=cellTree/ /g:ScrollPanel /g:center /g:DockLayoutPanel This DockLayoutPanel is in turn attached to other layout panel who is attached to the root layout panel. The behavior that I want is that when the user starts opening nodes in the tree and the cell tree grows bigger than the panel that contains it, a scroll bar will appear and the user can scroll and see all the nodes. The scroll bar never appears though. After searching on the net I found that I have to set the height is absolute units for the scroll panel. But how can I set it with absolute units, when I want the panel to fill the whole area, and I don't know how big the browser window will be? I guess there must be a simple solution to this, but I can't find it... Any ideas? Thanks, Ioan -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.
