Detailed Description

Base class for the Grid Layout nodes.

Grid Layout nodes arrange their items in a grid of cells. The grid node contains the definition for grid: the number and size of rows and columns. The grid items contain the coordinates of their cell, and the number of cells the item spans.

Member Typedef Documentation

◆ RowColumnDefinitionContainer

typedef vector<RowColumnDefinition> kanzi::GridLayoutConcept::RowColumnDefinitionContainer

Container type for row and column definitions.

Member Enumeration Documentation

◆ RowColumnSizeMode

enum kanzi::GridLayoutConcept::RowColumnSizeMode

Size mode for a grid row or a column.

Enumerator
RowColumnSizeModeUser	Row or column size is fixed.
RowColumnSizeModeAuto	Row or column size is the size of the largest item on this row or column.
RowColumnSizeModeWeighted	Row or column size is a proportion of the whole grid size. The proportion size depends on the relative weight of the row or column compared to weights of other rows or columns.

◆ GridDirection

enum kanzi::GridLayoutConcept::GridDirection

Direction of layout of grid layout. Items which don't have fixed ColumnProperty and RowProperty are laid out in this direction.

Enumerator
GridDirectionRight	Layout first right, then down.
GridDirectionDown	Layout first down, then right.

Member Function Documentation

◆ makeEditorInfo()

static PropertyTypeEditorInfoSharedPtr kanzi::GridLayoutConcept::makeEditorInfo ( )

static

◆ calculateWeightedSizes()

static void kanzi::GridLayoutConcept::calculateWeightedSizes	(	RowColumnDefinitionContainer &	definitions,
		float	weightMultiplier )

static

Calculates grid row or column definition maximum sizes for weighted rows or columns.

Parameters

definitions	Row or column definitions.
weightMultiplier	The size of a single weight unit.

◆ calculateOffsets()

static void kanzi::GridLayoutConcept::calculateOffsets ( RowColumnDefinitionContainer & definitions )

static

Calculates grid row or column definition offsets according to current maximum sizes.

Parameters

definitions Row or column definitions.

◆ accumulateMaximumSize()

static float kanzi::GridLayoutConcept::accumulateMaximumSize ( const RowColumnDefinitionContainer & definitions )

static

Calculates the sum of row or column definition's maximum sizes.

Parameters

definitions Row or column definitions.

Returns: Sum of row or column maximum sizes.

◆ parseRowColumnDefinitions()

static void kanzi::GridLayoutConcept::parseRowColumnDefinitions	(	const string &	definitionCollection,
		RowColumnDefinitionContainer &	definitions )

static

Parse grid row or column definitions from property string.

Parameters

definitionCollection	Property string describing grid rows or columns. See RowDefinitionsProperty for format definition.
definitions	Output parameter that will hold the row or column definitions.

Member Data Documentation

◆ DirectionProperty

PropertyType<GridLayoutConcept::GridDirection> kanzi::GridLayoutConcept::DirectionProperty

static

Direction property.

Defines the grid primary layouting direction. This property specifies how to choose the row and column for items without explicit grid row and column properties. The default value is GridLayoutConcept::GridDirectionRight.

See also: setDirection(), getDirection()

◆ ColumnDefinitionsProperty

PropertyType<string> kanzi::GridLayoutConcept::ColumnDefinitionsProperty

static

ColumnDefinitions property.

Defines the columns of the grid. See RowDefinitionsProperty. The default value is "".

See also: setColumnDefinitions(), getColumnDefinitions()

◆ RowDefinitionsProperty

PropertyType<string> kanzi::GridLayoutConcept::RowDefinitionsProperty

static

RowDefinitions property.

Defines the rows of a grid. The string format is "[*f|f];[*f|f];...", where:

';' separates row definitions
'f' signifies a float number
'*' signifies a weighted (proportional) height

For example:

"1.0;2.0;3.0;" defines three rows with heights of 1.0, 2.0, and 3.0.
";;" defines three rows that all have heights calculated from their content.
"*1.0;*2.0;*3.0;" defines three rows where the first row has 1/6 of the total height (Node::HeightProperty), the second 2/6 and the third 3/6. The default value is "".

setRowDefinitions(), getRowDefinitions()

◆ ColumnProperty

PropertyType<int> kanzi::GridLayoutConcept::ColumnProperty

static

Column property.

Defines the column of an item in a grid, starting from 0. The default value is 0.

See also: setColumn(), getColumn()

◆ ColumnSpanProperty

PropertyType<int> kanzi::GridLayoutConcept::ColumnSpanProperty

static

ColumnSpan property.

Defines how many columns this grid item spans. The default value is 1.

See also: setColumnSpan(), getColumnSpan()

◆ RowProperty

PropertyType<int> kanzi::GridLayoutConcept::RowProperty

static

Row property.

Defines the row of an item in a grid, starting from 0. The default value is 0.

See also: setRow(), getRow()

◆ RowSpanProperty

PropertyType<int> kanzi::GridLayoutConcept::RowSpanProperty

static

RowSpan property.

Defines how many rows this grid item spans. The default value is 1.

See also: setRowSpan(), getRowSpan()
