Detailed Description

flow container view that layout children in linear, and exceeds to next line or column if no enough space

a ZFUIFlowLayout is much similar to ZFUILinearLayout, except that ZFUIFlowLayout would exceeds children to next line or column if no enough space, which looks like "wrap" mode for text editors

Note

flow layout depends on expensive measure step, use only if necessary, and try to prevent deep child view tree, especially complex children

Member Function Documentation

classData()

virtual const ZFClass * ZFUIFlowLayout::classData ( void )

inlinevirtual

get instance's class info

Reimplemented from ZFUIView.

Reimplemented in ZFUIGridLayout.

DefaultStyle()

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

static

default style for ZFUIFlowLayout

orientation()

virtual ZFUIOrientation & ZFUIFlowLayout::orientation ( )

inlinevirtual

main direction to layout children, v_ZFUIOrientation::e_Left by default

v_ZFUIOrientation::e_Left means layout children from left to right, while v_ZFUIOrientation::e_Bottom means layout children from bottom to top

orientationSecondary()

virtual ZFUIOrientation & ZFUIFlowLayout::orientationSecondary ( )

inlinevirtual

secondary direction to layout children, v_ZFUIOrientation::e_Top by default

v_ZFUIOrientation::e_Left means layout children from left to right, while v_ZFUIOrientation::e_Bottom means layout children from bottom to top

Note

this direction must differs from orientation, otherwise, default value would be used
for example, if both orientation and orientationSecondary are x direction, then orientationSecondary would be treated as v_ZFUIOrientation::e_Top, and if they are both y direction, then orientationSecondary would be treated as v_ZFUIOrientation::e_Left

layoutParamClass()

virtual const ZFClass * ZFUIFlowLayout::layoutParamClass ( void )

inlineprotectedvirtual

see layoutParamCreate

you should override this method to declare your layout param class

Reimplemented from ZFUIView.

Reimplemented in ZFUIGridLayout.

layoutOnMeasure()

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

protectedvirtual

called by layoutMeasure to decide the view's size

you may override without call super to supply your own layout logic

note that we doesn't ensure layoutOnMeasure would be called during layout steps, only layout that has wrap content features may call layoutMeasure to calculate children's size

sizeHint means the max size child should reach, see ZFUISizeType for more info

return a negative value means the view doesn't care about size

Note

there's some repeatly work that layoutMeasure would have done for you, you should not repeat it again for performance:

• filter out the case that both sizeParam are fixed or fill parent
• apply sizeHint by ZFUILayoutParam::sizeHintApply
• fix result size in range [viewSizeMin, viewSizeMax]

for impl views (such as text view), you should manually take care of nativeImplViewMargin during measure and layout steps

Reimplemented from ZFUIView.

layoutOnLayout()

virtual void ZFUIFlowLayout::layoutOnLayout ( const ZFUIRect & bounds )

protectedvirtual

called by viewFrame to layout the view and children

it's valid for subclass to override without calling zfsuper::layoutOnLayout, which means subclass would override all layout steps in parent

note that we doesn't ensure layoutOnMeasure would be called before layoutOnLayout

Reimplemented from ZFUIView.
