C++ (Cpp) gpencil_layer_setactive Examples

Example #1

File: gpencil.c Project: linkedinyou/blender-git

/* add a new gp-layer and make it the active layer */
bGPDlayer *gpencil_layer_addnew(bGPdata *gpd, const char *name, int setactive)
{

	/* check that list is ok */
	if (gpd == NULL)
		return NULL;
		
	/* allocate memory for frame and add to end of list */
	gpl = MEM_callocN(sizeof(bGPDlayer), "bGPDlayer");
	
	/* add to datablock */
	BLI_addtail(&gpd->layers, gpl);
	
	/* set basic settings */
	copy_v4_v4(gpl->color, U.gpencil_new_layer_col);
	gpl->thickness = 3;
	
	/* auto-name */
	BLI_strncpy(gpl->info, name, sizeof(gpl->info));
	BLI_uniquename(&gpd->layers, gpl, DATA_("GP_Layer"), '.', offsetof(bGPDlayer, info), sizeof(gpl->info));
	
	/* make this one the active one */
	if (setactive)

}

Example #2

File: gpencil_buttons.c Project: 244xiao/blender

/* make layer active one after being clicked on */
static void gp_ui_activelayer_cb(bContext *C, void *gpd, void *gpl)
{
	/* make sure the layer we want to remove is the active one */
	gpencil_layer_setactive(gpd, gpl);
	
	WM_event_add_notifier(C, NC_GPENCIL | ND_DATA | NA_EDITED, NULL);
}

Example #3

	bGPdata *gpd   = (bGPdata *)ptr->id.data;
	bGPDlayer *gpl = BLI_findlink(&gpd->layers, value);

	gpencil_layer_setactive(gpd, gpl);
}

Example #4

/* delete 'active' layer */
