CustomTestWidget

[king558]

I just create a test custom widget. but it doesnt install it as plugins as expected. I am using Qt 5.8.0 free version and did following

1. Start QtCreator
2. New Project -> Other Project -> Qt Custom Desginer Widget
3. After creation this test custom project, I did not change anything.
4. Following is CustomizeWidget.pro file

CONFIG      += plugin debug_and_release
TARGET      = $$qtLibraryTarget(qtestwidgetplugin)
TEMPLATE    = lib

HEADERS     = qtestwidgetplugin.h
SOURCES     = qtestwidgetplugin.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(qtestwidget.pri)

5. After build the project. Netherless run qmake or Build All. Both failed copy *.dll to
   C:\Qt\Qt5.8.0\5.8\msvc2015\plugins\designer
6. In C:\Qt\Qt5.8.0\5.8\msvc2015\plugins\designer is only qaxwidget.dll and qquickwidget.dll. Not mine test dll

What did I wrong?

Hi and welcome to devnet,

Might be a silly question but did you call make install after building your plugin ?`

Adding to @SGaist
Or added it as a build step in Projects.

And its not such a silly question as for some reason I assumed if it had
anything to install it would also do that automatically :)

Thx for all answer. It must be release version to be load by designer, right?

Another question is

modified pro file

CONFIG      += plugin debug_and_release
TARGET      = $$qtLibraryTarget(qtestwidgetplugin)
TEMPLATE    = lib

HEADERS     = qtestwidgetplugin.h
SOURCES     = qtestwidgetplugin.cpp
RESOURCES   = icons.qrc
LIBS        += -L. 

greaterThan(QT_MAJOR_VERSION, 4) {
    QT += designer
} else {
    CONFIG += designer
}

target.path = $$[QT_INSTALL_PLUGINS]/designer

QMAKE_POST_LINK += xcopy /d/y $$qtLibraryTarget(qtestwidgetplugin) $$(QTCREATOR_BIN_PATH)/plugins/designer

INSTALLS    += target

include(qtestwidget.pri)

it result

xcopy /d/y qtestwidgetplugin C:\Qt\Qt5.8.0\Tools\QtCreator\bin/plugins/designer Invalid number of parameters

It must use the same version of Qt and compiler used to build Qt Creator and yes release.
