From 4774ff8eb1a653162ff76ae49d67137f720469b0 Mon Sep 17 00:00:00 2001 From: David Faure Date: Thu, 8 Aug 2013 12:37:00 +0200 Subject: Port rcc to QCommandLineParser. Before: ======= Qt resource compiler Usage: rcc [options] Options: -o file write output to file rather than stdout -name name create an external initialization function with name -threshold level threshold to consider compressing files -compress level compress input files by level -root path prefix resource access path with root path -no-compress disable all compression -binary output a binary file for use as a dynamic resource -namespace turn off namespace macros -project Output a resource file containing all files from the current directory -version display version -help display this information Undocumented: -verbose and -list ! After: ====== Usage: rcc [options] inputs Qt Resource Compiler version 5.2.0 Options: -h, --help Displays this help. -v, --version Displays version information. -o, --output Write output to rather than stdout. --name Create an external initialization function with . --root Prefix resource access path with root path. --compress Compress input files by . --no-compress Disable all compression. --threshold Threshold to consider compressing files. --binary Output a binary file for use as a dynamic resource. --namespace Turn off namespace macros. --verbose Enable verbose mode. --list Only list the files, do not generate code. --project Output a resource file containing all files from the current directory. Arguments: inputs Input files (*.qrc).
