ubuntu 9.10 request

[vampie]

On ubuntu and new brand linux with new Xorg there is a small bug

the screen is black but when you refresh ( by changing size of canvas of main container widget ) it becomes visible again
or adding component is doing the same..

Now for a workaround, could you do this:

when you open designer view is it possible to adding X+1 pixel, Y+1 pixel and removing it again X-1, Y-1 to trigger event for refresh
on linux ( not on windows ) ?


normal refresh button not doing the same (on design view)

thanks

We seen a couple of similar reports, but we cannot reproduce it. Probably this is a timing issue caused by preview window flickering prevention tricks: sometimes gecko refuses to render page. I'll add a workaround which you are requesting, but I'm not sure that it will help.

[Alexander.Mitin]

I've added the following just before take screenshot of preview window:

Code: Select all

Rectangle bounds = shell.getBounds();
shell.setSize(bounds.width - 1, bounds.height - 1);
shell.redraw();
shell.update();
shell.setSize(bounds.width, bounds.height);
shell.redraw();
shell.update();

This patch is available in GWT 1.7 support, GWT 1.5 has no such patch, so you can compare if it has effect.

when will 1.7 support available?




Latest Build Date - Microsoft WindowsLinux - RedHat or SuSEOSX

New GWT Designer v7.1 - What's New?
Requires GWT 1.4.62, 1.5.3, or 1.6.x


???
latest support is 1.6.x branch...

where will i download designer with 1.7.x support? ( http://download.instantiations.com/D2GW ... ate/E-3.5/ ) ???

Thanks

[Alexander.Mitin]

Version 7.1 works fine with GWT 1.7.

[vampie]

problem continues, when i add new component it becomes fixed...

It is something annoying

[Alexander.Mitin]

It is possible to make an option which would disable any flickering prevention tricks. This should solve 'black screen' problem, but you'll see a more annoying popping out preview window every time you make even a minor change. Say your 'thanks' to developers of Linux window managers who made window managers so 'smart': they disallow showing a window in offscreen area and forsibly bring the window in front of you. And there is no any technical restriction to show the window in offscreen area. This is a major WindowBuilder (not only GWTD) problem under Linux since the beginning of java WindowBuilder early in 2003.

I understand the problem, same as freebsd... when popup windows is not shown it will not render the screen...

when would you make such an option... like render timeout option..???

Thanks

[Alexander.Mitin]

The latest build pays attention to 'com.instantiations.gwt.disablePreviewWindowWorkarounds' system property. Define it and assign 'yes' or 'true' value to it like this
-Dcom.instantiations.gwt.disablePreviewWindowWorkarounds=true.
Again, this is for GWT 1.7 Linux support only.
Next, using this option try to switch to Compiz window manager. It's 'smart' too but it has nice feature (still not considered as a bug <g>): it wouldn't render a window on screen if it closed immediately after open.

[vampie]

where will i define it ???

in eclipse.ini ???

or with command line to eclipse executable?

$./eclipse -D..... ??

[Alexander.Mitin]

./eclipse -vmargs -Dcom.instantiations.gwt.disablePreviewWindowWorkarounds=true

[vampie]

now it has been fixed... thanks...

when will you make them available for GWT 1.4 - 1.5 - 1.6 ???

and would you make it available for FreeBSD too ? ( again for all version for GWT )

[Eric Clayberg]

when will you make them available for GWT 1.4 - 1.5 - 1.6 ?

This is available for GWT 1.4 through 1.7 in the latest build.

and would you make it available for FreeBSD too ?

FreeBSD is not one of our officially supported environments, so we don't doing any testing there.

Have you tried our normal Linux build there?

[vampie]

FreeBSD is not one of our officially supported environments, so we don't doing any testing there.

yes i know, I have compiled and sent you libgwt*.so, i hope it will also show popup window as linux does ( metacity and compiz )
showing popup windows should not bother linux ppl, coz you can set windows "always on top"

that is why i asked about any change in linux environment ( such as new VMARGS for eclipse ) also effect FBSD...

Thanks for your support su far...

And yes for linux it is ok for now... new window managers + new xorg + new mozilla render library would cause a future bug..
so we found a workaround for now

I am your beta tester i will also test on solaris

[Alexander.Mitin]

It should work on FreeBSD as same as on Linux (though FreeBSD never tested at our end).
