There was a subtle flaw in the way fluxbox detects to which BScreen a
given Window belongs: We have to compare the RootWindow of the given
Window against the RootWindow of each BScreen.
That underlying flaw made _NET_REQUEST_FRAME_EXTENTS fail: the code path
needs a valid BScreen for the given window, otherwise we return early.
Closes#1121.
Note: I expect only modern compilers will hit the source of fluxbox. It
seems futile to guard stdlib headers while demanding <algorithm> etc. This
should trim down the noise in the source quite a bit.
Do not try to be too smart which compilations need config.h, as most of
them will simply because of the config.h has information about system
capabilities.
fluxbox now properly displays windows that require ARGB visuals when
an external compositor is running. This was done by creating the
container window with the correct visual and colormap when needed.
Closes#2874629
Introduces a new member function, FbWindow::cardinalProperty()
This change also changes other code that previously used
FbWindow::property() to do the same thing as the new function; this
reduces code duplication.
There are still some bits of code (Ewmh.cc, extractNetWmIcon()) that use
FbWindow::property() to retrieve XA_CARDINAL values, but as the new
method is designed for getting a _single_ property, and that code uses
FbWindow::property() to retrieve the number of values present, and then
grab all of them; it's a different use case. I opted to not try to make
cardinalProperty() into some monolithic all-purpose cardinal method;
FbWindow::property() works just fine for that.
This change also adds an optional (default=NULL) boolean to
FbWindow::textProperty and friends that allows the caller to determine
whether or not a value was actually retrieved. This was necessary for
integrating FbWindow::cardinalProperty with the codebase, and it seemed
to fit with FbWindow::textProperty as well. Prior to this change, if
you got a return value of "", you wouldn't know if you successfully
retrieved the value which happened to be blank, or if you failed to
retrieve the value. Now, you can pass the address of a boolean if you
so choose in order to differentiate these situations; the same applies
to the new FbWindow::cardinalProperty().
WindowMenuAccessor returned strange alpha values if compiled
with 'g++ -Os'; unholy black magic happens if template<int> faces
functions returning only 'usigned char'.
"carrier" (maybe a temporarly name?) ... carriers dont need background-updates
.. ever.
this leads to a big performance"boost" over the last commits. before we
updated also the windows which are the hosts for the apps (m_window and
m_clientarea in FbWinFrame) -> bad idea.
