Detailed Description

native image view

Member Function Documentation

classData()

virtual const ZFClass * ZFUIImageView::classData ( void )

inlinevirtual

get instance's class info

Reimplemented from ZFUIView.

DefaultStyle()

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

static

default style for ZFUIImageView

objectOnInit()

virtual void ZFUIImageView::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
}

Reimplemented from ZFUIView.

objectOnDeallocPrepare()

virtual void ZFUIImageView::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 ZFUIView.

objectInfoImplAppend()

virtual void ZFUIImageView::objectInfoImplAppend ( zfstring & ret )

protectedvirtual

see objectInfo

Reimplemented from ZFUIView.

nativeImplViewMarginImplUpdate()

virtual void ZFUIImageView::nativeImplViewMarginImplUpdate ( ZFUIMargin & nativeImplViewMargin )

protectedvirtual

see nativeImplViewMargin, subclass must call super and "append" to existing margin

Reimplemented from ZFUIView.

nativeImplViewOnLayout()

virtual void ZFUIImageView::nativeImplViewOnLayout ( ZFUIRect & ret, const ZFUIRect & bounds, const ZFUIMargin & nativeImplViewMargin )

protectedvirtual

called to layout nativeImplView

Reimplemented from ZFUIView.

layoutOnMeasure()

virtual void ZFUIImageView::layoutOnMeasure ( ZFUISize & ret, const ZFUISize & sizeHint, const ZFUISizeParam & sizeParam )

protectedvirtual

image view would measure according image size

Reimplemented from ZFUIView.

viewTreeVisibleOnUpdate()

virtual void ZFUIImageView::viewTreeVisibleOnUpdate ( void )

protectedvirtual

see E_ViewTreeVisibleOnUpdate

Reimplemented from ZFUIView.
