IE_GETFORMAT

Retrieves the current format of a stroke or a set of strokes in an iedit control.

Parameters

wParam

Not used; must be 0.

lParam

Address of a STRKFMT1AOCY8 structure.

Return Value

If successful, returns bit flags that indicate whether the strokes identified in the STRKFMT structure have different color or width, as described in the  Comments  section.

If an error occurs, returns one of the following values:

Constant

Description

IER_ERROR

Unknown error.

IER_PARAMERR

wParam or lParam is invalid. Also returned when there is an invalid stroke index and the IESF_STROKE option is specified in the iesf member of the STRKFMT1AOCY8 structure.

IER_SECURITY

The control has security protection disallowing the operation.

IER_SELECTION

No valid selection when the IESF_SELECTION option is specified in the iesf member of the STRKFMT1AOCY8 structure.

 

Comments

If the value in the iesf member of the STRKFMT1AOCY8 structure has the IESF_STROKE bit set, IE_GETFORMAT refers to the single stroke identified in the iStrk member. In this case:

    The return value is 0.

    The bwidth and rgb members in PENTIP1AOCX_ specified in the STRKFMT structure contain the stroke s color and width.

 

If either the bit IESF_SELECTION or IESF_ALL is set in iesf, IE_GETFORMAT retrieves format information for multiple strokes. In this case, the return value con-tains the IESF_TIPCOLOR or IESF_TIPWIDTH bit flags that indicate whether the multiple strokes share the same ink color and width.

For example, if the multiple requested strokes all have the same width, then

    The IESF_TIPWIDTH bit of the return value is 0 to indicate the strokes all have the same width.

    The bwidth member in PENTIP1AOCX_ specified in the STRKFMT1AOCY8 structure contains the common width.

 

If the strokes do not all have the same color, IE_GETFORMAT returns the following information:

    The IESF_TIPCOLOR bit is set in the return value to indicate the strokes do not share a common color.

    The rgb member in PENTIP specified in the STRKFMT structure contains the color of the last stroke in the group.

 

The caller must initialize the cbSize member of the STRKFMT structure to sizeof( STRKFMT ) before sending IE_GETFORMAT.

The supplied STRKFMT1AOCY8 structure specifies the stroke or strokes for which the attributes are desired. The structure is filled according to the request and the actual stroke attributes.
