Callback from Javascript

harun — Sat, 18 May 2013 08:40:35 GMT

Hi All,

I must communicate applet by javascript api.

If Applet has any action, applet call javascript function webphonetojs(varr);

At this point I must callback this varr from GWT method, to show user about the action.

I can send my commands to applet by (JSNI) native methods. But I couldn't get callback from applet.

I want to ask you how can I implement webphonetojs javascript method from GWT, and how can call GWT method.

Working javascript code is following:

Code:

ssinai — Wed, 08 May 2013 20:17:39 GMT

I'm using a grid with GroupingStore and GroupingView. The three groups are

Core
Alternate Core
Additional Measures

I need to order the groups in the above order, but they're showing up in the following order

Additional Measures
Alternate Core
Core

Anyone know what I need to do to override the alphabetical sort?

Thanks.

GXT 2.2.5 NumericFilter extention

BobbyGe — Fri, 03 May 2013 12:33:06 GMT

Hi every one,

I have a grid that show some information and some colums of this grid shows the duration of some task. the duration is in seconds so for a better looking I apply a render that convert the value in this format "hh: mm: ss". And all works perfect. Now I add the filter plugin to the grid and I chose NumericFilter for these colums, The problem is that the number that the user enter for the filter I want to rapresent the number of minutes and not the number of second, so I extend the NumericFilter class and override the getValue method with the following code:

Code:

       @Override

        public List getValue()

        {

            Debug();

            List filteList = super.getValue();

            List retval = new ArrayList();

            for (FilterConfig filter : filteList) {

                String value = String.valueOf(filter.getValue());

                try {

                    double timeValue = 60 * Double.parseDouble(value);

                    value = String.valueOf(timeValue);

                } catch (NumberFormatException e) {

                    retval = super.getValue();

                    break;

                }

                filter.setValue(value);

                retval.add(filter);

            }

            return retval;

        }

When I use server filtering all works perfect because I call this method, but when I use local filtering this method is ignored.

Can some one tell me which method I should override or which event I should catch???

Thanks in advance

Grid alignment issue in Google Chrome

alarifth0 — Fri, 03 May 2013 09:04:50 GMT

As soon as i update a value of a BeanModel in the Gxt Grid the alignment of that row goes awful. It only happens in Chrome (Version 26.0.1410.64 m). It works fine in IE9 and Firefox 20.0.1. Here i have attached the screenshot of the grid

Development environment:
GWT = 2.4
GXT = 2.2.5
JDK = 1.6

Any suggestions please?

How to manually call resize on a changed Viewport

baze — Sun, 21 Apr 2013 02:04:43 GMT

Hi all,

I spent about 3-4 hours fighting with this, and maybe someone can point me what Im missing!

I use extgwt(its un older project) and I have extended the Viewport which dose window resize tracking
in a class like this

public class MainFrame extends Viewport {

final BorderLayout layout = new BorderLayout();

code where border layout components are added

public void fireMainViewResize(){
windowResizeTask.delay(windowResizeDelay);
// onWindowResize(Window.getClientWidth(), Window.getClientHeight());

}

In one of the components, which is added in the viewport as a BorderLayout.Left, on runtime(after initial show) I add some child components and this makes perent component to incrise in its y size. This is all expected. After this I want to re-draw the component so it can addopt to this new size and fit the viewport size again.

I tried calling layout, layout(force=true) but dose nothing.
Then I tried calling window resize on the Viewport with a layout(force), also nothing.

If I manualy resize the browser all get adopted to the viewport size, so I cannot find out what else is actually called when the browser is relly resized.

I did a try to call all the related Window.resizeHandlers by jsni methods because they are not visible,
once like this:

private native void fireManulaWindowResize() /*-{
try {
$wnd.console.log("fireManulaWindowResize start");
$wnd.onresize(new Object());
$wnd.console.log("fireManulaWindowResize end");

} catch (err){
$wnd.console.log("Error on manual call for resize: " + err);
}

}-*/;

and like this

private native void fireManulaWindowResize() /*-{
try {
$wnd.console.log("fireManulaWindowResize start");
@com.google.gwt.user.client.Window::onResize()();
$wnd.console.log("fireManulaWindowResize end");

// $wnd.alert("$wnd.resized");

} catch (err){
$wnd.console.log("Error on manual call for resize: " + err);
}

}-*/;

No exception in the calles, but the added handleres are never executed...

Someone idea on how to force the viewport to re-renderer(re-calculate) its children sizes and paint again?

Tnx for any idea,
Blaze
