TPJWdwStateReadEvent = procedure(

) of object;
property OnReadWdwState: TPJWdwStateReadEvent;
This event is triggered just after the window placement, size and state data is read from storage but before displaying the window. The data can be modified in the event handler before the window is displayed, enabling the size, placement and state of the window to be changed.
Setting any of the parameters to MaxInt causes the default value for the parameter to be used. These default values come from the relevant properties of the related form.
If Options property contains the woIgnoreState value then any changes to the State parameter in the event handler are ignored. Similarly if Options contains woIgnoreSize then changes to Width and Height are ignored and default values are used. Finally, if Options contains woFitWorkArea then the Top, Left, and (if woIgnoreSize is not specified) Width and Height values may be altered to ensure the window fits in the workspace.
The event is protected in TPJCustomWdwState. It may be exposed by derived components.
