RESIZE_QUEUED 
Todo:
Comment this.
EXTREMES_QUEUED 
Todo:

NEEDS_RESIZE 

Set, when dw::core::Widget::requisition is not up to date anymore.

Todo:
Update, see RESIZE_QUEUED.
NEEDS_ALLOCATE 

Only used internally, set to enforce size allocation.

In some cases, the size of a widget remains the same, but the children are allocated at different positions and in different sizes, so that a simple comparison of old and new allocation is insufficient. Therefore, this flag is set (indirectly, as ALLOCATE_QUEUED) in queueResize.

ALLOCATE_QUEUED 
Todo:
Comment this.
EXTREMES_CHANGED 

Set, when dw::core::Widget::extremes is not up to date anymore.

Todo:
Update, see RESIZE_QUEUED.
WAS_ALLOCATED 

Set, when a widget was already once allocated,.

The dw::Image widget uses this flag, see dw::Image::setBuffer.

The actual implementation for calculating dw::core::Widget::extraSpace.

The implementation gets a clean value of dw::core::Widget::extraSpace, which is only corrected. To make sure all possible influences are considered, the implementation of the base class should be called, too.

◆ calcFinalWidth()

void dw::core::Widget::calcFinalWidth ( style::Style style,
int  refWidth,
Widget refWidget,
int  limitMinWidth,
bool  forceValue,
int *  finalWidth 
)

Computes the final width if posible and constraints it by min-width and max-width.

This function performs a very particular computation. It will try to find the fixed width of the style provided by taking the refWidth or refWidget as the reference to expand relative values.

The value of *finalWidth is used to initialized the first value of width, so it can be used to initialize a width when the style sets the width property to auto.

If both the initial *finalWidth and the style with are -1, the value will be left as is, even if min-width and max-width could contraint the size. For the width to be constrained, either the initial *finalWidth or the computed width should return an absolute value.

Postcondition
If *finalWidth != -1 the computed *finalWidth value is guarantee not to be -1.

◆ calcWidth()

int dw::core::Widget::calcWidth ( style::Length  cssValue,

Computes a width value in pixels from cssValue.

If cssValue is absolute, the absolute value is used. If cssValue is relative, then it is applied to refWidth. Otherwise, -1 is used.

In any case, the returned value is clamped so that is not smaller than limitMinWidth.

)
protected

Correct a child requisition aspect ratio if needed.

After the parent widget corrects the requisition provided by the

Parameters
child,thepreferred aspect ratio may no longer be the current ratio. This method tries to adjust the size of the requisition so the aspect ratio is the preferred aspect ratio of the child.

It implements three passes: increase (0), decrease (1) or keep (2). In the increase pass, the size is increased to fill the aspect ratio. If after correcting the size, it is still not the preferred aspect ratio (maybe it breaks some other constraint), reducing the size will be attempted. If at the end, reducing the size doesn't fix the preferred aspect ratio, the size is kept as it is.

It can be called from the parent or the child itself, as it doesn't read any information from the current widget.

Returns
true if the requisition has been modified, false otherwise.

Return an iterator for this widget.

mask can narrow the types returned by the iterator, this can enhance performance quite much, e.g. when only searching for child widgets.

With atEnd == false, the iterator starts before the beginning, i.e. the first call of dw::core::Iterator::next will let the iterator point on the first piece of contents. Likewise, With atEnd == true, the iterator starts after the last piece of contents, call dw::core::Iterator::prev in this case.
