Detailed Description

root native window

use mainWindow to access app's main window, use modalWindowShow to show a new window, use nativeWindowEmbed to attach to native impl, never create ZFUISysWindow's instance manually

Member Function Documentation

classData()

virtual const ZFClass * ZFUISysWindow::classData ( void )

inlinevirtual

get instance's class info

Reimplemented from ZFObject.

notified when window rotated, new orientation can be accessed by sysWindowOrientation

E_SysWindowMarginOnUpdate()

static zfidentity ZFUISysWindow::E_SysWindowMarginOnUpdate ( void )

static

see ZFObject::observerNotify

notified when sysWindowMargin changed, param0 is a v_ZFUIMargin that holds the old window margin

E_SysWindowOnKeyEvent()

static zfidentity ZFUISysWindow::E_SysWindowOnKeyEvent ( void )

static

see ZFObject::observerNotify

notified when ZFUIKeyEvent fired to the window, and none of it's view handled the event by ZFUIEvent::eventResolved
param0 is the ZFUIKeyEvent

nativeWindowEmbed()

static zfautoT< ZFUISysWindow > ZFUISysWindow::nativeWindowEmbed ( ZFUISysWindowEmbedImpl * embedImpl )

static

used to embed ZFUISysWindow to existing UI framework

ZFUISysWindow would create internal native window by default, however, you may create your own native window and attach ZFUISysWindow to it
to achieve this feature, you must supply custom embed impl by ZFUISysWindowEmbedImpl, call this method to get an attached ZFUISysWindow, and manually manage the life cycle of the returned ZFUISysWindow

the embedImpl would be retained until the created window destroy, so that you only need to take care of the created window, to explicitly clear all the contents, simply use window->nativeWindowEmbedImplDestroy()

see ZFUISysWindowEmbedImpl for all the impl that you need to implement

nativeWindowEmbedImplDestroy()

virtual void ZFUISysWindow::nativeWindowEmbedImplDestroy ( )

virtual

util to destroy the window created by nativeWindowEmbed

equal to ZFUISysWindowEmbedImpl::notifyOnPause

• ZFUISysWindowEmbedImpl::notifyOnDestroy

nativeWindowEmbedNativeView() [1/2]

static zfautoT< ZFUISysWindow > ZFUISysWindow::nativeWindowEmbedNativeView ( void * nativeParent )

static

default impl to attach window to native view

note, after attach, you must destroy the window by nativeWindowEmbedImplDestroy before destroy the nativeParent
the nativeParent must support add one or more child which fill itself

nativeWindowEmbedNativeView() [2/2]

static zfautoT< ZFUISysWindow > ZFUISysWindow::nativeWindowEmbedNativeView ( void * nativeParent, const zfstring & sysWindowName )

static

util to attach window to native view, and register a getter method with specified name

usage:

zfauto sysWindow = ZFUISysWindow::nativeWindowEmbedNativeView(nativeParent, "MyWindow");
if(sysWindow != zfnull) {
    zfobj<ZFUIWindow> window(ZFInvoke("MyWindow"));
    ...
}

mainWindowRegister()

static void ZFUISysWindow::mainWindowRegister ( ZFUISysWindow * window )

static

manually register main window, must be called before accessing mainWindow

this method is useful if you want to embed whole ZFFramework to existing UI framework, to create a custom ZFUISysWindow, see nativeWindowEmbed

Note

you must manually manage the life cycle of the registered ZFUISysWindow

once registered, it can not be changed back to original internal window, until ZFFrameworkCleanup

it's safe to unregister and register a new window, but you must ensure you won't access the children of the window after you do so

mainWindow()

static zfanyT< ZFUISysWindow > ZFUISysWindow::mainWindow ( )

static

get application's main window

usually, use only one window is recommended
the main window would be created and attached automatically when first time accessed (directly or implicitly by showing a ZFUIWindow), and can not be changed after creation
to embed ZFFramework to native framework, you may use mainWindowRegister

sysWindowSize()

virtual const ZFUISize & ZFUISysWindow::sysWindowSize ( )

virtual

native window's size

to change window's size or layout, use sysWindowLayoutParam
to observe window size change, attach ZFUIView::E_ViewLayoutOnLayoutFinish listener to rootView

sysWindowMargin()

virtual const ZFUIMargin & ZFUISysWindow::sysWindowMargin ( )

virtual

native window margin according to impl

the margin usually used for mobile phones, whose edge contains virtual button or front camera
by default, ZFUIWindow would automatically exclude the margin, you may change it by ZFUIWindow::sysWindowMarginShouldApply

objectOnInit()

virtual void ZFUISysWindow::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 ZFObject.

objectOnInitFinish()

virtual void ZFUISysWindow::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 ZFUISysWindow::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.

objectOnDealloc()

virtual void ZFUISysWindow::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.

nativeWindow()

virtual void * ZFUISysWindow::nativeWindow ( )

virtual

access the internal native window

note, this value would be valid only after E_SysWindowOnCreate
note, this value can be null if window created by nativeWindowEmbed

nativeWindowIsCreated()

virtual zfbool ZFUISysWindow::nativeWindowIsCreated ( )

virtual

true if sys window created

Note

for some implementation, creating a ZFUISysWindow may or may not create native window immediately, you may use this method as well as E_SysWindowOnCreate to see when did window created, typical usage:

ZFUISysWindow *newWindow = ZFUISysWindow::mainWindow()->modalWindowShow();
if(!newWindow->nativeWindowIsCreated()) {
    ZFListener observer = ... {
        initWindow();
    };
    newWindow->observerAdd(ZFUISysWindow::E_SysWindowOnCreate(), observer);
}
else {
    initWindow();
}

modalWindowShow()

virtual zfautoT< ZFUISysWindow > ZFUISysWindow::modalWindowShow ( )

virtual

show a new modal window, may or may not show immediately, may have different behavior on different implementations

use only if necessary
it's recommended that app have only one ZFUISysWindow, use ZFUIWindow if necessary

rootView()

virtual zfanyT< ZFUIRootView > ZFUISysWindow::rootView ( )

virtual

access the root view of the window

the root view is ensured ZFUIRootView type, and you must not add it to another view
