CMake can I filter compiler output through another program -

-

can tell cmake pipe stderr output compiler and/or linker through external program , showing output of on terminal instead?

for makefile generators can apply filter compiler output setting custom launcher compile rules. following cmake list file sketches necessary steps:

cmake_minimum_required(version 2.8)  project (main)  configure_file(     "${project_source_dir}/gcc_filter.sh.in"     "${project_binary_dir}/gcc_filter.sh"     @only)  add_executable (main main.cpp)  set_property(global property rule_launch_compile "${project_binary_dir}/gcc_filter.sh")

in project root directory add following shell script template file gcc_filter.sh.in:

#!/bin/sh  # shell script invoked following arguments # $(cxx) $(cxx_defines) $(cxx_flags) -o object_file -c source_file  # invoke compiler exec "$@" 2>&1 | "@project_source_dir@/myfilter.sh"

the actual shell script invoked custom launcher rule first copied project binary directory configure_file call in cmake list file. executable bit of file gcc_filter.sh.in must set. shell script forwards arguments compiler , pipes compiler output shell script myfilter.sh in project root directory:

#!/bin/sh exec wc

the example myfilter.sh invokes wc more elaborate output filtering can done using above recipe.

python - Subclassed QStyledItemDelegate ignores Stylesheet -

-
i'm trying subclass qstyleditemdelegate remove focus rectangle in qcombobox . even though i'm calling base implementation of paint function , nothing else, result different. looks if parts of style-sheet influence bounding box of item taken consideration. class pstyleditemdelegate(qstyleditemdelegate): def __init__(self, *args, **kwds): super(pstyleditemdelegate, self).__init__(*args, **kwds) def paint(self, *args, **kwargs): qstyleditemdelegate.paint(*args, **kwargs) what have paint unmodified qstyleditemdelegate ? as suggested tried replacing pyside pyqt4 , works, appears bug. update pyside 1.1.2 1.2.1 result same. unfortunately switch breaks other parts of code, if there no other suggestions i'm going accept answer. edit bug tracked here
