Maven dependecy mangement artiafctId with ${project.artiafctId} -

-

in parent child :

<project> ... <dependencies>     <dependency>         <groupid>${parent.groupid}</groupid>         <artifactid>${parent.artifactid}-war</artifactid>         <type>war</type>     </dependency> </dependencies> ...  </project>

in parent :

<project> ... <dependencymanagement>     <dependencies>         <dependency>             <groupid>${project.groupid}</groupid>             <artifactid>myproject-war</artifactid>             <version>${project.version}</version>             <type>war</type>         </dependency>     </dependencies> </dependencymanagement> ...  </project>

just wondering why using (in parent) 

<artifactid>myproject-war</artifactid>

is working , using

<artifactid>${project.artifactid}-war</artifactid>

is not working

[0]  'dependencies.dependency.version' missing be.lab:myproject-war:war

you should think setup. apart updating last maven version (3.1.1)..

 root -- pom.xml    +--- m1 (pom.xml)    +--- m2 (pom.xml)    +--- m3 (pom.xml)

you root (parent) looks this:

<project ....>   <modelversion>4.0.0</modelversion>    <groupid>com.soebes.maven.training</groupid>   <artifactid>parent</artifactid>   <packaging>pom</packaging>   <version>1.0.0-snapshot</version>    <modules>     <module>m1</module>     <module>m2</module>     <module>m3-war</module>   </modules>    ... </project>

a typical childs looks ths:

i suggest define dependencies between child in childs this:

<project ..>  <modelversion>4.0.0</modelversion>  <parent>   <groupid>com.soebes.maven.training</groupid>   <artifactid>m1</artifactid>   <version>1.0.0-snapshot</version> </parent>  <artifactid>m1</artifactid>  </project>

a child dependency other child looks this:

<project ..>  <modelversion>4.0.0</modelversion>  <parent>   <groupid>com.soebes.maven.training</groupid>   <artifactid>m1</artifactid>   <version>1.0.0-snapshot</version> </parent>  <artifactid>m2</artifactid>  <dependencies>   <dependency>     <groupid>${project.group}</groupid>     <artifactid>m1</artifactid>     <version>${project.version}</version>   </dependency> </dependencies>  </project>

furthermore usage of things ${parent.*} isn't practice.

and lets have @ war module:

<project ..>  <modelversion>4.0.0</modelversion>  <parent>   <groupid>com.soebes.maven.training</groupid>   <artifactid>m1</artifactid>   <version>1.0.0-snapshot</version> </parent>  <artifactid>m3-war</artifactid>  <dependencies>   <dependency>     <groupid>${project.group}</groupid>     <artifactid>m2</artifactid>     <version>${project.version}</version>   </dependency> </dependencies>  </project>

i recommend not use such constructs <artifactid>${parent.artifactid}-war</artifactid>. better use in such situations <artifactid>module-war</artifactid> cause wouldn't save much.

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
