    <p>I just started a Qt5 project using cmake as build system. So far this working quite well but I have problems with an icon that I want to load from a qrc file. </p> <p>Project structure:</p> <pre><code>CMakeLists.txt -- icons/ CMakeLists.txt icons.qrc locked.png -- src/ CMakeLists.txt source files... </code></pre> <p>Top Level CMakeLists.txt:</p> <pre><code>cmake_minimum_required(VERSION 2.8.11) #2.8.11 provides an easy way to build with qt5 project(fluchOmat) # Find includes in corresponding build directories set(CMAKE_INCLUDE_CURRENT_DIR ON) # Instruct CMake to run moc automatically when needed. set(CMAKE_AUTOMOC ON) # Find the QtWidgets library. This has dependencies on QtGui and QtCore! find_package(Qt5Widgets REQUIRED) # Find the QtMultimedia module find_package(Qt5Multimedia REQUIRED) add_subdirectory(icons) add_subdirectory(src) </code></pre> <p>CMakeLists.txt in icons/</p> <pre><code>set(RESOURCE ${CMAKE_CURRENT_SOURCE_DIR}/icons.qrc ) qt5_add_resources(RESOURCE_ADDED ${RESOURCE}) </code></pre> <p>icons.qrc in icons/</p> <pre><code>&lt;RCC&gt; &lt;qresource prefix="/"&gt; &lt;file alias="locked"&gt;locked.png&lt;/file&gt; &lt;/qresource&gt; &lt;/RCC&gt; </code></pre> <p>CMakeLists.txt in src/ (important part)</p> <pre><code>add_executable(fluchOmat ${SOURCES} ${HEADERS} ${fluchOmat_FORMS} ${RESOURCES_ADDED}) </code></pre> <p>Some sample code </p> <pre><code>QPixmap pm(":/locked.png"); qDebug("Width: " + pm.width()); </code></pre> <p>returns nothing, so obviously this didn't work. </p> <p>There aren't many resources out there for Qt5 and cmake. Can anyone help me with this? Is this a cmake problem? For example I am not sure if qt5_add_resources is at the right location. Is my qrc file wrong? </p> <p>Any help is greatly appreciated!</p>

    1. COAs your image file has an alias in the resource, does it still fail if you use QPixmap(pm(":/locked"); without the file extension?

    3. COWell, the resource file and requesting of the image look fine, so I'd assume the problem is with how cmake is including the resource file.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
