@keyterms:
layout object class, child widgets
@title:
layout class
@type:
class
@short:
Manages child widget geometry
@inherits:
[class]object[/class]
@description:
The layout is a geometry management tool for child widgets.
You create a layout, give it some widgets to manage and it will layout them
automatically.[br]
The parent of the layout must be the widget for which child widget geometries have to be managed.
A layout is a grid of NxM cells in which you insert child widgets with [classfnc:layout]$addWidget[/classfnc]().[br]
Widgets that must span multiple cells can be added to the layout with [classfnc:layout]$addMultiCellWidget[/classfnc]().[br]
@functions:
!fn: $addWidget(<widget:object widget>,<row:uint>,<column:uint>)
Adds a widget to this layout placing it at position <row>,<column> in the grid
!fn: $addMultiCellWidget(<widget:object widget>,<start_row:uint>,<end_row:uint>,<start_col:uint>,<end_col:uint>)
Adds a widget to this layout spanning multiple grid cells
!fn: $setRowStretch(<row:uint>,<stretch:uint>)
Sets the stretch value for a particular row of this layout.[br]
The <stretch_value> must be a positive integer.[br]
The rows with bigger stretch values will take more space in the layout.
!fn: $setColumnStretch(<column:uint>,<stretch:uint>)
Sets the stretch value for a particular column in this layout.[br]
The <stretch_value> must be a positive integer.[br]
The rows with bigger stretch values will take more space in the layout.
!fn: $addRowSpacing(<row:uint>,<spacing:uint>)
Sets the minimum height of the specified <row> to <spacing> which must be a positive integer
!fn: $addColSpacing(<column:uint>,<spacing:uint>)
Sets the minimum width of the specified <column> to <spacing> which must be a positive integer
!fn: $setSpacing(<spacing:uint>)
Sets the default spacing of the widgets in pixels
!fn: $setMargin(<margin:uint>)
Sets the dimension of the layout margin: the distance from the border to the outermost child widget edges.
!fn: $setAlignment(<w:widget>, <flag1:string>, <flag2:string>, ...)
Sets the alignment for widget w to flags, given as parameters.
Valid flags are: Right, Left, Top, Bottom, HCenter, VCenter, Center
!fn: $setResizeMode(<resize_mode:string>)
Sets the resize mode of the parent widget in relation to this layout.
<mode> can be one of:[br]
[pre]
-Auto: this is the default
-Fixed: the parent widget of this layout is resized to the "sizeHint" value and it cannot be resized by the user.
-Minimum: the minimum size of the parent widget of this layout is set to minimumSize() and it cannot be smaller
-FreeResize: the parent widget of this layout is not constrained at all
