const

const DISPPARM& GRE::LAYER_SCRIPT::GetDispParm

(

)

const [inline]

Retrieve layer-specific display parameters.

virtual int GRE::LAYER_SCRIPT::OpenObject	(	UINT32	filemode = RVCFILE_ReadLock,
		MDLGPARENT	dlgparent = 0
	)			[virtual]

Open object(s) for this layer.

Returns:

TRUE if was opened, FALSE if open already, < 0 if error

Parameters:

filemode	RVC file access mode
dlgparent	Parent for dialog

Reimplemented from GRE::LAYER.

static void GRE::LAYER_SCRIPT::RegisterType

(

)

[static]

Register this layer type.

ERRVALUE GRE::LAYER_SCRIPT::SetDispParm

(

const DISPPARM &

dispparm

)

Set layer-specific display parameters.

This is the recommended method for changing how an existing layer is to be rendered. Validation will be performed on the specified parameters and adjustments made to the layer's copy if necessary. Use of this method usually result in a ChangeBegin / ChangeEnd message pair, and will also generate a ChangeObject message if the spatial object used in the layer is changed.

Parameters:

dispparm
