Detailed Description

default scroll thumb for ZFUIScroller

Member Function Documentation

◆ classData()

virtual const ZFClass * ZFUIScrollThumbDefault::classData ( void )

inlinevirtual

get instance's class info

Reimplemented from ZFStyle.

◆ DefaultStyle()

static zfanyT< ZFUIScrollThumbDefault > ZFUIScrollThumbDefault::DefaultStyle ( void )

static

default style for ZFUIScrollThumbDefault

◆ objectOnInit()

virtual void ZFUIScrollThumbDefault::objectOnInit ( void )

protectedvirtual

override this to init your object

subclass must call superclass's objectOnInit before any other code if override
you may also declare objectOnInit with params like this:

zfclass Parent : ... {
    ...
protected:
    virtual void objectOnInit(void) {...};
};
zfclass Child : Parent {
protected:
    // override all parent's objectOnInit is also required,
    // because of function hiding of C++
    zfoverride
    virtual void objectOnInit(void) {
        zfsuper::objectOnInit();
    }
    // custom init entry
    virtual void objectOnInit(Params...) {
        // your extra init steps
        ...
    }
};

Warning: objectOnInit and objectOnDealloc is called as a virtual function, take good care of other virtual function call, use zfself::func() instead of this->func() if necessary, or use objectOnInitFinish/objectOnDeallocPrepare, or declare your own constructor with ZFOBJECT_DECLARE_WITH_CUSTOM_CTOR

Note: (ZFTAG_LIMITATION) due to limitations of C++, if your parent type declared objectOnInit with different params, and your child type want to override part of those objectOnInit, then your child type must also override all objectOnInit that parent declared, otherwise, some may be hidden; for objects that designed not to be allocated by user, you should use ZFOBJECT_PRIVATE_ALLOC, typically usage:
zfclass MyObject : zfextend ZFObject {

ZFOBJECT_DECLARE(MyObject, ZFObject)

ZFOBJECT_PRIVATE_ALLOC("should be created by MyObject::instanceForXxx only")

public:

static zfauto instanceForXxx(xxx) {

// can only be allocated by reflection

return zfself::ClassData()->newInstance();

}

};

static void func(void) {

// MyObject *obj = zfAlloc(MyObject); // would compile error

zfauto obj = MyObject::instanceForXxx(xxx); // OK

}

zfextend
#define zfextend
dummy macro shows class inherit from another
Definition ZFCoreTypeDef_ClassType.h:53

ZFOBJECT_DECLARE
#define ZFOBJECT_DECLARE(ChildClass, SuperClass,...)
necessary for every class inherit from ZFObject
Definition ZFObjectDeclare.h:126

ZFOBJECT_PRIVATE_ALLOC
#define ZFOBJECT_PRIVATE_ALLOC(...)
mark this object can not be allocated directly
Definition ZFObjectDeclare.h:245

ZFClass::newInstance
zfauto newInstance(void) const
make a new instance of ZFObject dynamically, which is described by ZFClass

ZFUIScrollThumbDefault::ClassData
static const ZFClass * ClassData(void)
get class info
Definition ZFUIScrollThumbDefault.h:20

zfauto
a ZFObject holder which would release content object automatically when destroyed
Definition zfautoFwd.h:34

Reimplemented from ZFObject.

◆ objectOnDealloc()

virtual void ZFUIScrollThumbDefault::objectOnDealloc ( void )

protectedvirtual

override this to destroy your object

subclass must call superclass's objectOnDealloc after any other code if override
see objectOnInit for more info

Reimplemented from ZFObject.

◆ objectOnInitFinish()

virtual void ZFUIScrollThumbDefault::objectOnInitFinish ( void )

protectedvirtual

called after objectOnInit, safe to call virtual functions here

usually used to initialize independent resources other than self's internal resources

Reimplemented from ZFObject.

◆ objectOnDeallocPrepare()

virtual void ZFUIScrollThumbDefault::objectOnDeallocPrepare ( void )

protectedvirtual

called before objectOnDealloc, safe to call virtual functions here

usually used to cleanup resources attached to this object other than self's internal resources

Note: it's ensured safe to retain the object while deallocating, but it's not ensured objectOnDeallocPrepare would only called once for each instance

Reimplemented from ZFObject.

◆ scrollThumbInit()

virtual void ZFUIScrollThumbDefault::scrollThumbInit ( void )

virtual

init the scroll thumb

Implements ZFUIScrollThumb.

◆ scrollThumbDealloc()

virtual void ZFUIScrollThumbDefault::scrollThumbDealloc ( void )

virtual

destroy the scroll thumb

Implements ZFUIScrollThumb.

◆ scrollThumbUpdate()

virtual void ZFUIScrollThumbDefault::scrollThumbUpdate ( void )

virtual

update the scroll thumb, this method may be called repeatly

you may update thumb depending on ZFUIScrollView::scrollViewState

Implements ZFUIScrollThumb.
