@description:
|
|
The tqlayout is a tqgeometry management tool for child widgets.
|
|
You create a tqlayout , give it some widgets to manage and it will tqlayout them
|
|
automatically.[br]
|
|
The tqparent of the tqlayout must be the widget for which child widget geometries have to be managed.
|
|
A tqlayout is a grid of NxM cells in which you insert child widgets with [classfnc:tqlayout]$addWidget[/classfnc]().[br]
|
|
Widgets that must span multiple cells can be added to the tqlayout with [classfnc:tqlayout]$addMultiCellWidget[/classfnc]().[br]
|
|
@functions:
|
|
!fn: $addWidget(<widget:object widget>,<row:uint>,<column:uint>)
|
|
Adds a widget to this tqlayout 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 tqlayout spanning multiple grid cells
|
|
!fn: $setRowStretch(<row:uint>,<stretch:uint>)
|
|
Sets the stretch value for a particular row of this tqlayout. The <stretch_value>
|
|
must be a positive integer. The rows with bigger stretch values will take more space
|
|
in the tqlayout.
|
|
!fn: $setColStretch(<column:uint>,<stretch:uint>)
|
|
Sets the stretch value for a particular column in this tqlayout. The <stretch_value>
|
|
must be a positive integer. The rows with bigger stretch values will take more space
|
|
in the tqlayout.
|
|
!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 specigfied <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 tqlayout margin : the distance from the border to the outermost child widget edges.
|
|
!fn: $setResizeMode(<resize_mode:string>)
|
|
Sets the resize mode of the tqparent widget in relation to this tqlayout.
|
|
<mode> can be one of:[br]
|
|
-Auto: this is the default[br]
|
|
-Fixed: the tqparent widget of this tqlayout is resized to the "tqsizeHint" value and it cannot be resized by the user.[br]
|
|
-Minimum: the minimum size of the tqparent widget of this tqlayout is set to tqminimumSize() and it cannot be smaller[br]
|
|
-FreeResize: the tqparent widget of this tqlayout is not constrained at all[br]
