COLUMN

This is basically the same as <CELL layout_type="column"> 

Attributes brief detailed show all inherited

	Name	Description	Default
Inherited from cell
Properties Relative to Parent Cell
	v_align	Vertical alignment of the cell in its parent cell	center
	h_align	Horizontal alignment of the cell in its parent cell	center
	h_position	Horizontal position of the cell in its parent cellIf defined, it deactivates the h_align property. Use this attribute for horizontal pixel-positioning. The position is relative to the parent cell
	v_position	Vertical position of the cell in its parent cellIf defined, it deactivates the v_align property. Use this attribute for vertical pixel-positioning. The position is relative to the parent cell
	h_offset	horizontal offset of the cell from the position computed by the layout engineUsing this property lets you move a cell without changing the layout around it. The position is relative to the parent cell	0
	v_offset	vertical offset of the cell from the position computed by the layout engineUsing this property lets you move a cell without changing the layout around it. The position is relative to the parent cell	0
	flex	flexibility of the cellThis attribute is used when the parent cell is a row or a column and has free space to distribute to children cells (for example for a fixed size parent cell that is larger than the sum of its children cell sizes). The remaining space will be distributed among children cells according to the flex attribute value	0
	display	include/exclude the cell from the layoutWhen set to false, the content of the cell is not displayed (not visible) AND is not taken into account to compute the layout (the cell is ignored)	true
Cell Properties
	width	Forced width of the cellIf not present, the width will be automatically computed from the children cells widths and layout rules
	min_width	minimum width allowed for the cellWhen set, the layout engine will ensure that the width of the cell is not smaller than min_width pixels
	max_width	maximum width allowed for the cellWhen set, the layout engine will ensure that the width of the cell is not larger than max_width pixels
	height	Forced height of the cellIf not present, the height will be automatically computed from the children cells heights and layout rules
	min_height	minimum height allowed for the cellWhen set, the layout engine will ensure that the width of the cell is not smaller than min_height pixels
	max_height	maximum height allowed for the cellWhen set, the layout engine will ensure that the width of the cell is not larger than max_height pixels
	margin	margin of the cellMay be overridden by the h_margin or v_margin attributes	0
	h_margin	Horizontal margin of the cell	0
	v_margin	Vertical margin of the cell	0
	spacing	Space between children cells	0
	spacing_flex	Flex value to allocate extra space between children cellsSee the flex attribute for more details	0
	internal_v_align	Vertical alignment of children cells group inside the cellThis attribute is useful only if the cell has a fixed size, and the sum of the sizes of the layouted children cells is different from the cell size. In this case you may want to choose how you align the children cells group inside the parent cell. Used only for 'column' type cell, the horizontal alignment being set individually for each child cell	center
	internal_h_align	Horizontal alignment of children cells group inside the cellThis attribute is useful only if the cell has a fixed size, and the sum of the sizes of the layouted children cells is different from the cell size. In this case you may want to choose how you align the children cells group inside the parent cell. Used only for 'row' type cell, the vertical alignment being set individually for each child cell	center
	reflow	when set to true, the layout engine will treat chidren cell as reflowable elements. For a fixed height column, the width is computed accordingly, and for a fixed width row, the height is computed accordinglyvalid only for columns with fixed height or rows with fixed width	false
	flip	display children cells in reverse order (right to left or bottom to top)currently valid only for COLUMN and ROW elements	false
Inheritable properties: these text properties are inherited by children cells (and can be overridden)
	font_face	Name of the font for text contained in the cell and sub cellsFonts are not the same on all systems, so you should carefuly select the fonts or ensure that users have specific fonts installed	empty
	font_size	Size of the font for any text contained in the cellIf the value starts with + or -, the resulting font size is incremented by this value from the current font size. If the value ends with a %, the resulting font size is the corresponding proportion of the current font size. This value is inherited by children cells but can be overridden	System...
	font_size_mode	Defines how font size is computed to select the right font.Default value is cell mode for backward compatibility reasons but it has been deprecated. It is however recommended to use "character" mode for more precise font size selection. Using the cell size to select the font is less precise and not compatible with standard font sizes expressed in character height.	cell

	font_style	Style of the font for any text contained in the cellThe value is inherited by children cells but can be overridden	System...
	font_quality	Quality of the fontThe value is inherited by children cells but can be overridden	System...
	font_escapement	Escapement (angle in degrees) of the fontThe value is inherited by children cells but can be overridden. If the escapement of the font is non null, the formating options of the text widgets won't apply	0

Examples

There is nothing special for this element compared to a CELL element. You can rewrite the same examples as for the CELL, replacing <CELL layout_type="column"> with <COLUMN>. Note that the layout_type attribute cannot be changed.
