How to set my preferences panel ?

1:if I wirte all the project in C++ with qt , then according to the .pro file , the customed widget will be compiled correctly . But now I just write .qrc file ,which contains a .ui file . Does it do any help that I copied FreeCAD_widgets.dll and FreeCAD_widgets.lib to $QTDIR/plugins/designer

The FreeCAD_widgets plugin is only needed by the Qt Designer. At runtime of FreeCAD we don't need this plugin because all the relevant widgets classes are built into the FreeCADGui library.

2:I convert the .qrc file to python with pyrcc4.exe , that is to say , I compile the .qrc file with python , does this mean that I should copy FreeCAD_widgets.dll and FreeCAD_widgets.lib to $PyQt4/plugins/designer ? If the answer is yes , the third question comes

The location of FreeCAD_widgets is totally irrelevant to pyrcc4 because this utility only creates a Python module that converts the content of the .ui file to Qt's resource format.

Thank you wmayer , the reply help confirm something .
At current time , I put FreeCAD_widgets plugin to $QTDIR/plugins/designer , and edit a .qrc file and .ui file in a seperate folder .
In 'promotion' of QtDesigner , header file and subclass name is needed , in Draft preference page 'userprefs-base.ui' , buttons belong to class 'Gui:PrefColorButton' , in my editing , I could see the 'Gui:PrefColorButton' option , but the 'Promote' button is unabled when I selected 'Gui:PrefColorButton' . Is this because I didn't put relevant header files in right place ? Then should I copy relevant header files ? If I don't need do this , how does QtDesigner know and use this class ?

btw , I have a irrelevant question , .ui file is a txt file without implement , QtDesigner doesn't need to know the structrue of classes , then what is the role of FreeCAD_widgets plugin to QtDesigner ?

I don't know how the "Promoted widgets" function is supposed to work in QtDesigner but you don't need this if you have a working plugin. The plugin contains all the required information and put this into the .ui file. If you open the .ui file you'll find a section <customwidgets> where class name, base class and header file is listed.

This is to make FreeCAD widgets behave as built-in Qt widgets, i.e. you can choose them from the widget box and drag and drop them to the UI form.

Hi,

Does any one have a pre-compiled FreeCAD_widgets.dll I can use? (32 bit windows system)
