Detailed Description

Abstract BLayout subclass arranging items within rows and columns.

This class manages all the tricky work of actually positioning/resizing items, as well as calculating size constraints and providing extra features, such as spacing/insets and alignment of multiple BTwoDimensionalLayout's. Derived classes need only implement a few hook methods to get a working layout.

Warning: This class is not yet finalized, if you use it in your software assume that it will break some time in the future.

Member Function Documentation

◆ AddInsets() [1/2]

BSize BTwoDimensionalLayout::AddInsets ( BSize size )

protected

Add the size to all the insets for this layout.

Since: Haiku R1

◆ AddInsets() [2/2]

void BTwoDimensionalLayout::AddInsets	(	float *	minHeight,
		float *	maxHeight,
		float *	preferredHeight
	)

protected

Add to the insets, and store the modified values.

Parameters

[out]	minHeight	The value to add to the minimum height for this layout. The new minimum height is stored at the variable of this pointer.
[out]	maxHeight	The value to add to the maximum height for this layout. The new maximum height is stored at the variable of this pointer.
[out]	preferredHeight	the value to add to the preferred height for this layout. The new preferred heifght is stored at the variable of this pointer.

Since: Haiku R1

◆ AlignLayoutWith()

void BTwoDimensionalLayout::AlignLayoutWith	(	BTwoDimensionalLayout *	other,
		orientation	orientation
	)

Align the BLayoutItem's in the specified orientation within two or more BTwoDimensionalLayout's.

When two (or more) BTwoDimensionalLayout's are aligned within a certain orientation, then the BLayoutItem's within those BTwoDimensionalLayout's will have identical widths or heights (depending on how the BTwoDimensionalLayout's are aligned.)

If you align two BGroupLayout's horizontally for example, then the BLayoutItem at index 0 in both BGroupLayout's will be given the same horizontal area. The same is true for the BLayoutItem at index 1, 2, etc. Not all BTwoDimensionalLayout's have to have an item at each index for the alignment to proceed.

Parameters

other	The BTwoDimensionalLayout to be aligned with.
orientation	The orientation on which to be aligned.

Since: Haiku R1

◆ AllArchived()

virtual status_t BTwoDimensionalLayout::AllArchived ( BMessage * into ) const

protectedvirtual

Method relating to the use of BArchiver.

This hook function is called once the first BArchiver that was created in an archiving session is either destroyed, or has its Finish() method called. Implementations of this method can be used, in conjunction with BArchiver::IsArchived(), to reference objects in your archive that you do not own, depending on whether or not those objects were archived by their owners. Implementations of this method should call the implementation of their parent class, the same as for the Archive() method.

Warning: To guarantee that your AllArchived() method will be called during archival, you must create a BArchiver object in your Archive() implementation.; You should archive any objects you own in your Archive() method implementation, and NOT your AllArchived() method.
