QT自定义插件/控件

插件.pro文件配置：

CONFIG      += plugin debug_and_release

TARGET      = $$qtLibraryTarget(qimagebuttonplugin)

TEMPLATE    = lib

HEADERS     = qimagebuttonplugin.h

SOURCES     = qimagebuttonplugin.cpp

RESOURCES   = icons.qrc

LIBS        += -L. 

greaterThan(QT_MAJOR_VERSION, 4) {

    QT += designer

} else {

    CONFIG += designer

}

target.path = $$[QT_INSTALL_PLUGINS]/designer

INSTALLS    += target

include(qimagebutton.pri)

QWidget *QImageButtonPlugin::createWidget(QWidget *parent)

{

    return new QImageButton(parent);

}
