Filter list (left side panel) in WebUI is implemented using <a> tags,
CSS defines default style for all <a> elements, and specific style for
filter list elements. Default style for <a> elements sets color, and
this color also used in list. This is looks not so well. So lets just
inherit text color from parent element, and as so as it is not set, so
default text color will be used.
This makes filter list looks like other UI elemets, making all UI more
consistent (like in desktop app).
1. Use unified function names `initInstance()` and `freeInstance()` and
make them public.
2. Add `freeInstance()` to avoid noise from memory leak detectors.
3. Let `instance()`return a pointer directly to avoid unnecessary
indirections when invoking functions.
This will allow browsers to get high quality icon with required
resolution instead of resizing some small raster image.
Browsers can have even more benefit from it. For example, Firefox uses
high resolution icon to display it in "Top Sites" instead of page
preview.
Nothing changes for browsers which doesn't support SVG favicons, older
PNG icon will be used in such case.
The basic idea is to hash each class member and then mix them with xor
operation.
However the `seed` must be handled with care, it should only be
introduced once when mixing the hashes of each class member, otherwise
under some circumstances the `seed` might xor with itself and thus break
the intended effect.
When the CMake system was last revamped, the configure variable was
changed from WEBUI to DISABLE_WEBUI, but we are still checking
against WEBUI. This behavior was changed in fa770871e9
If we were conditionally enabling _BSD_SOURCE or _SVID_SOURCE, I can
understand trying to play nice with the compiler and only pass as
needed, however this is not the case and glibc <= 2.19 will not care
that we are passing _DEFAULT_SOURCE. This removes an unnecessary
build step and gives us less to maintain from a build system
perspective.
Small cosmetic changes to MacroQbtCompilerSettings are included.
Our previous setup lead to two unintended consequences:
* Debug flags were included in both release and debug builds instead
of just debug builds
* Clang doesn't support -gX (where X is the level of debugging
optimization), but we checked for -Og support instead
This commit avoids both of these scenarios by removing the additional
flags altogether. Partial resolution to #11856.
