Display comboBox like list with Q_PROPERTY

shootstar

hi raven-worx, thank you for your replay!
i have use an enum type ,like "enum ParamTypeList{...}", but it also not solve my problem, and if the property defined as enum, it will not be displayed in the property page.

thanks,

i think you also have to specify the "Q_ENUMS macro":http://qt-project.org/doc/qt-4.8/qobject.html#Q_ENUMS in your class definition so Qt knows about it

shootstar

well, i specify the Q_ENUMS macro, like "Q_ENUMS(ParamTypeList)",and it has passes the compiler and linker. But the property does't display in the property in the property page still.

raven-worx

just to make sure: you subclass QObject (or a class which inherits QObject) and you have Q_OBJECT macro specified?

my .h file just like this:
class AxisCoord : public QWidget, public QAxBindable
{
Q_OBJECT
Q_ENUMS(ParamTypeList)
Q_PROPERTY( QString nctype READ GetType WRITE SetType)
Q_PROPERTY( int value READ value WRITE setValue )
Q_PROPERTY(ParamTypeList ParamType READ getParamType WRITE setParamType)

public:
AxisCoord(QWidget *parent = 0);

QString GetType() const;
int value() const;
enum ParamTypeList
{
TYPE1,
TYPE2,
TYPE3
};

ParamTypeList getParamType() const;
... //other code
}

my .h file just like this:
@class AxisCoord : public QWidget, public QAxBindable
{
Q_OBJECT
Q_ENUMS(ParamTypeList)
Q_PROPERTY( QString nctype READ GetType WRITE SetType)
Q_PROPERTY( int value READ value WRITE setValue )
Q_PROPERTY(ParamTypeList ParamType READ getParamType WRITE setParamType)

public:
AxisCoord(QWidget *parent = 0);

QString GetType() const;
int value() const;

enum ParamTypeList
{
TYPE1,
TYPE2,
TYPE3
};

ParamTypeList getParamType() const;

QComboBox getCombobox() const;

...//other code

hmm...please clean your project, rerun qmake and try again.

I don't think that i makes a difference but you can give it also a try: specify the Q_ENUMS macro after the Q_PROPERTY macros. Like in this "example":http://qt-project.org/doc/qt-4.8/properties.html#a-simple-example.

thank you very much! when i clean my project, and add the actviex again, the property has displayed at last. I'm really very grateful to you!

hi, raven-worx, i encounter a new problem. now, the property can be displayed, but when i modify the QAxWidget property which displayed in comboBox(include defined property), as:
@ //ui_test_active.h
axWidget->setProperty("FocusPolicy", QVariant(QAxWidget::NoFocus));
axWidget->setProperty("ParamType", QVariant(QAxWidget::TYPE2));
axWidget->setProperty("cursor", QVariant(QAxWidget::UpArrowCursor));
@
you know, the "FocusPolicy" and "cursor" property are the defualt property, only the "ParamType" is the new property. but when i build the project, there are errors, as:
@1>E:\HNC11\test_active\test_active\GeneratedFiles\ui_test_active.h(45): error C2039: 'NoFocus' : is not a member of 'QAxWidget'
1> d:\qt\qt5.0.2\5.0.2\msvc2010\include\activeqt\qaxwidget.h(59) : see declaration of 'QAxWidget'

1>E:\HNC11\test_active\test_active\GeneratedFiles\ui_test_active.h(48): error C2065: 'UpArrowCursor' : undeclared identifier@
i have no idea to solve those error, can you help?

the compiler error says it all: "error C2039: 'NoFocus' : is not a member of 'QAxWidget'"
Your enum values are not defined in QAxWidegt but in Qt namespace. So use Qt::NoFocus and Qt::UpArrowCursor.

And btw. why do you use to set these properties with with the setter for dynamic properties (i mean the setProperty() method)? I think there is nothing wrong with this code, but it is more error prone and there are qwidget setters available.

shootstar

thank you for your help!
the code which in "ui_test_active.h" is automatically created by the system, i just modify the activeX property in Qt designer, then the system automatically generates those codes ("ui_test_active.h" file), so how can i do? whether is there some wrongs with my system configuration?
