Browser Widget focus [message #120981]

It's probably just something I'm missing, but I'm having an issue with
Browser widget.

I have browser widget inside dialogs, and in order to click on a link
inside the browser I need to click twice to get it to work. After the
first extra click, the browser seems to have focus and will work as normal
(single clicks).

So I tried to do setFocus() and forceFocus() but both returns false. Why
would the widget fail to get focus? Or is this a bug?

Thanks in advance,
Howard

I too am having this problem. The HTML page I am displaying in the
Browser component contains href links but I have to click inside the
Browser component initially in order to make the links responsive. The
status bar in the RAP browser does not display the link URL until the
first mouse click is received.
Thanks

Hi Howard,

I can't reproduce it with Controls Demo -> Browser tab. When I set the
page in the browser, the links became active immediately. Can you
provide a simple self-running snippet that illustrate the problem?

Best,
Ivan

Try this. Basically just a shell with browser in it. I'm wondering if it
has anything to do with me running RWT standalone? If you need a war file
to test RWT standalone, you can see my previous thread "File Upload and
Download in RWT standalone", I attached a war file there.

Thanks!

Shell shell = new Shell(display, SWT.TITLE);
shell.setLayout(new GridLayout());

Browser browser = new Browser(shell, SWT.NONE);

browser.setLayoutData(new GridData(GridData.FILL_BOTH));

Hi Howard,

the browser widget uses qooxdoo Iframe. I've dig inside the qooxdoo
Iframe and found that there is a blocker div element which cover the
actual Iframe when the instance is created. As a temporary workaround
add the following code in the RAP Browser.js file:
focus : function() {
this.base( arguments );
this.release();
}
This release (remove) the blocker div tag on Browser focus gain.

Best,
Ivan

Thanks for taking the time to investigate, Ivan.
Alas I tried to add that snippet to Browser.js but it doesn't seem to do
anything. I wouldn't be surprised if I'm not adding it correctly though,
so would you kindly past the entire file for me?

Also, out of curiosity, is this a RWT standalone issue since you said the
demo browser works fine?

Cheers,
Howard

Howard,
This is not a RWT standalone issue. I've opened a bug about it:

[Browser] Extra click is needed to activate the link in the browser widget

Ivan,

Would you please update the bug with the temporary work-around you posted?
Attaching the entire Browser.js would be good because I still can't figure
out where/how to add your snippet. :(

Interesting why the browser demo would work fine and that this bug wasn't
caught earlier.

Thanks,
Howard

Hi Howard,

the iframe blocker is removed automatically, when you click somewhere in
the application. In the Controls Tab -> Browser, the browser widget is
empty by default and the blocker is there. When you click somewhere in
the application (button to set the URL for example)... the blocker is
removed. In your example the browser widget is "preloaded" with the
page, that's why there is no this first click to remove the blocker. The
bug is fixed in CVS HEAD - the blocker is removed on iframe "load" event
as qooxdoo developers suggested.

Best,
Ivan
