Thanks.

From memory, QWidget::activateWindow() and possibly QWidget::raise()
could be relevant.

Bring an application to focus

[Felipe Crochik]

Is there a way to make my application after receiving a dbus signal become
active and visible? If the application is not running it starts
automatically on the top and it is visible/focused, but if my application is
already running how can I make its main window become visible/focused when
it is "behind some other application"? I tried setFocus() (qt) but it does
not seem to make any difference.

 

Thanks

Felipe

How to keep hildon-plugin-manager from loading plugins before the package is installed completely?

[pHilipp Zabel]

Hi,

I tried to find the cause for
https://bugs.maemo.org/show_bug.cgi?id=10798 (installation of
status-area-applet-tor crashes hildon-status-menu), so I ran
hildon-status-menu from the terminal before installing the Tor Status
Area Applet from h-a-m:

# /usr/sbin/dsmetool -k /usr/bin/hildon-status-menu
# DEBUG_OUTPUT=1 /usr/bin/hildon-status-menu
[...]
atus-menu[27821]: GLIB DEBUG default - plugin-added:
/usr/share/applications/hildon-status-menu/status-area-applet-tor.desktop
atus-menu[27821]: GLIB DEBUG default - load_plugin_idle. Try to load
plugin_id: status-area-applet-tor.desktop
atus-menu[27821]: GLIB ERROR ** default -
status-area-applet-tor.vala:118: Icon 'statusarea_tor_disabled' not
present in theme
aborting...

So during installation, the plugin is loaded but causes SIGABRT
because it can't find a theme icon that is part of the package:

# dpkg -L status-area-applet-tor | grep "\(disabled\|\.desktop\)"
/opt/maemo/usr/share/icons/hicolor/48x48/hildon/statusarea_tor_disabled.png
/usr/share/applications/hildon-status-menu/status-area-applet-tor.desktop
/usr/share/icons/hicolor/48x48/hildon/statusarea_tor_disabled.png

My assessment of the situation is that hildon-status-menu loads the
plugin as soon as status-area-applet-tor.desktop is unpacked. It then
races against the unpacking process and wins. It tries to load the
icon before the maemo-optified link
/usr/share/icons/hicolor/48x48/hildon/statusarea_tor_disabled.png is
created.
Is this what happens? What should I do about it - I guess I can't stop
h-s-m from prematurely loading the plugin?

best regards
Philipp

RE: capturing key presses on N770

[Vinod Nanjaiah]

Frantisek, thanks a lot for your inputs.
This is the use case:
   I want to run a video streaming client in the foreground.
   In the background I want to run a process that captures the key presses 
and invokes a
   script to do something more.

I haven't yet had a peek at the evkey.c and bootmenu.sh - hope this is it.

Thank you,
Vinod

Not sure what is the scenario you want to use it for. For low level
access you can use kernel input subsystem directly

see e.g. evkey.c [1] and its usage in bootmenu.sh [2]. Just beware that
different devices have different device names and key events still go to
the rest of the system.

For playing nice with the system using powerlaunch [3] is indeed better.
I am not aware of 770 version (the author [4] has/had N800) but the
source is here [4]. Maybe it could build fine at least in OS2007 hacker
edition.

QLineEdit and casing

[Mats Rauhala]

I have trouble with uppercase letters with QLineEdit. I'm using
QLineEdit as an input method for adding items to a list/set. The user
write an item and presses return which causes the text to be handled and
the QLineEdit cleared. But if the user wants to add another item, the
text is no longer title cased. If the QLineEdit loses focus and regains
it, the casing is nulled and the first line is again title cased. I'd
like the texts to be always or never title cased for consistency.

As far as I understand the title casing is caused by Maemo input methods,
but I wasn't able to figure out the keywords for figuring out how to fix
this.

Yes they show up fine after restart. Thank you for pointing me to the

RE: capturing key presses on N770

[Vinod Nanjaiah]

Hi,
I came across Powerlaunch which can capture and map a hard key to any user 
defined action.
But, can Powerlaunch work while running in the background or does it need to 
run in the foreground?
BTW, I was not able to find a .deb package for powerlaunch - Any links from 
where this can be downloaded?

Frank, thanks for your input.

Thank you,
Vinod

Hi,

With C and GTK it's certainly possible, I do so in TabletBridge.

Hi,

not show in the menu.

   


Basically the sources for the icons are different. The application 
manager shows the icon it finds in the control file of the debian 
folder, while the icon in the task launcher is based on the one in the 
icons folder. But can you see the blue square as the default icon in the 
task launcher? Then your problem is probably related to a bug [1] in the 
system. Does your icon shows up after a restart?
