Missing icons
Message 1 in thread
Hello,
I am running qtopia 4.2.1 on an ARM-based board, but am missing icons.
On the screen which should look something like:
http://www.trolltech.com/images/products/qtopia/phone_edition_4_gridshot.jpg/image
, I see the background image and button outlines, but no icons (see
attached image).
When I press an arrow button, I guess qpe wants to redraw some icons and
I see messages like this on stdout:
QPainter::begin: Paint device returned engine == 0, type: 3
QPainter::save: Painter not active
QPainter::setMatrix: Painter not active
QPainter::setMatrix: Painter not active
QPainter::setRenderHint: Painter must be active to set rendering hints
QPainter::setRenderHint: Painter must be active to set rendering hints
QPainter::setMatrix: Painter not active
QPainter::setMatrix: Painter not active
I'm not sure if it matters, but on my target file system, I have the
file /opt/Qtopia/pics/qpe/SettingsIcon.svg, but no corresponding PNG
file. I noticed in some cases there are both SVG and PNG versions of a
file:
/opt/Qtopia/pics/appearance/icons/background.png
/opt/Qtopia/pics/appearance/icons/background.svg
, so as an experiment, I created SettingsIcon.png and restarted qpe, but
saw no change.
Is there something simple I missed during configuration or in the
environment?
Thanks!

Did you run 'make install'? and then use Qtopia as well as the sqlite db
that was created in image/ ?
Icons and application paths are now stored in the database, .desktop
files are only used at compile/install time for Qtopia.

Hi Lorn,
Yes, I did do 'make install' and the timestanp on image/qtopia_db.sqlite
looks correct, but we have other steps in our build system which puts
files in a target binary RPM, so maybe that has messed up paths.
Are there host tools in qtopia to modify the database file, or is there
a place in the build where I might need to make changes? The file is
created in src/tools/content_installer/main.cpp, right?

Hi Lorn,
I used the SQLite command line tools and dumped the (6) tables in
qtopia_db.sqlite. In the locationLookup table (assuming it's the right
place to look), I have:
INSERT INTO "locationLookup" VALUES(1, '/opt/Qtopia/apps/Settings');
INSERT INTO "locationLookup" VALUES(2, '/opt/Qtopia/etc/SystemRingTones');
INSERT INTO "locationLookup" VALUES(3, '/opt/Qtopia/plugins/inputmethods');
INSERT INTO "locationLookup" VALUES(4, '/opt/Qtopia/apps/Applications');
INSERT INTO "locationLookup" VALUES(5, '/opt/Qtopia/apps/Games');
The SystemRingTones and inputmethods paths exist on my target, but
there's no "/opt/Qtopia/apps". I only see the apps directory in the
source, which has the .desktop files.
Thanks,

There should also be a db in $HOME/Applications/Qtopia. You should be
able to just rename or delete this.

Hi Lorn,
Thanks for the suggestion. I tried renaming
$HOME/Applications/Qtopia/qtopia_db.sqlite, but there are still no icons.
After grepping for "iconpath" in the source and putting a couple of
printfs in QtopiaApplication::applyStyle(), at runtime I got:
qpe config file=/root/Settings/Trolltech/qpe.conf
theme=smart.conf
themeCfg file=/opt/Qtopia/etc/themes/smart.conf
iconPathText=
Any idea if an empty path at this point is a bad thing?
Thanks,

A bit more information on this problem in case anyone is interested.
I found that the icons were not being rendered from SVG because the icon
size returned by GridItem::getBasicImageSize() was zero. I tracked this
back to QtopiaStyle::pixelMetric(PM_IconViewIconSize, ..)'s setting
'size' to zero since QApplication::desktop()->screen()->logicalDpiY()
returned zero.
As an experiment, I hardcoded 'size' to '20' in pixelMetric() and icons
were drawn.
I'm still looking for the root cause, but at least I'm getting closer.

I found that this problem was simply a matter of a missing environment
variable $QWS_DISPLAY. I've set the display, restarted qpe, and it
looks much better.
