GetPositionStrategy( control type [, strategy ] )
| GetPositionStrategy | Returns the repositioning strategy for a control type. |
| control type | An integer constant, variable, EQUATE, or expression indicating the type of control (BUTTON, ENTRY, LIST, etc.). |
| Strategy | An integer constant, variable, EQUATE, or expression indicating the overall strategy for resizing and repositioning all the controls on the window. If omitted, strategy defaults to the strategy specified by the Init method. |
The GetPositionStrategy method returns the appropriate repositioning strategy for a particular control type based on the overall strategy.
Implementation:
The Reset method calls the GetPositionStrategy method to set the position strategy for dynamically created controls.
EQUATEs for the control type parameter are declared in EQUATES.CLW. Each control type EQUATE is prefixed with CREATE:.
EQUATEs for the return value are declared in ABRESIZE.INC. Each strategy EQUATE is prefixed with Resize:.
Example:
GET(SELF.ControlQueue,SELF.ControlQueue.ID) !get control resize info
IF ERRORCODE() !if no control info, add it
SELF.ControlQueue.Type=FieldCounter{PROP:Type} ! set control type
SELF.ControlQueue.ParentID=0 ! set parent
SELF.ControlQueue.HasChildren=False ! set children
SELF.ControlQueue.ID=FieldCounter ! set ID
GetSizeInfo(FieldCounter,SELF.ControlQueue.Pos)! set coordinates
! set resize strategies
SELF.ControlQueue.PositionalStrategy=SELF.GetPositionStrategy(SELF.ControlQueue.Type)
SELF.ControlQueue.ResizeStrategy=SELF.GetResizeStrategy(SELF.ControlQueue.Type)
ADD(SELF.ControlQueue,SELF.ControlQueue.ID) ! add control info
ASSERT(~ERRORCODE())
