more intuinitve configuration interface in graphicalitem. Improve code
for the future references (in case if new color type will be added).
Change X-AW-*Color values to ones with prefixes (added autoconversion
from old-version api)
* translation update
* fix broken build with gcc (#87). The issue was reproduced only with
gcc build and has been resolved by just replacing C-like `isnan` to
`std::isnan`
Sources in custom dataengine updated only if user subscribe on specified
source. I've implemented drop returing value so if no requested value
found it will return force update event.
Bump API version and add new parameters. Also:
1. Fix function combobox in configuration UI.
2. Drop datasource from time engine as well.
3. Small edit abstractdesources class
As it was found the issue has been caused by parallel access to
QGraphicsScene so it has been cleared before convertion to pixmap. It
has been resolved by deletion concurrent updates in this place (it makes
sense anyway).
This commits series introduces bars which may be calculated from any
custom formula. For a start I've renamed $bar*tag to $bar* and add new
configuration parameters to graphical items.
The previous versions stored values as string, so any (even if they are
not used) values being converted into string, and then (if required)
being converted back to float/int/etc. I've changed the mechanism, so
they are stored as QVariant (native value).
Please note that it is possible that this rewrite may cause crash in
some cases (if I've missed smth).
I've added 'optimize' option (by default true). If it options is set
then sources will be checked if they are required (with dependencies if
any). And if they are not required they will be dropped by using common
mechanism.
Please note that if this option enabled the following features (at the
moment) will be unavailable:
* key request from context menu (from configuration interface it still works)
* notifications event if sources on which notification is not connected
I suppose this commit will increase performance in about 4-5 times.
Move old chechUpdates() method to this class. Create ability to show
ChangeLog after updates (by using global config with version). Changelog
(only for the latest version) will be written to version.h during cmake
run.
