Re: My own add feature function

Hello Myzzard,

Here is a code snippet that I added to the GasMain MDL example to automatically annotate the feature after placement if the AutoAttribute system property is TRUE. This system property setting is available in the Feature pulldown menu.



Public void placeGasMain_secondPoint


(


Dpoint3d *pntP,


int view


)


{


BoolInt autoAttribute = FALSE;


generateGasMain (pntP, view);


 


xfmFeature_write (gasMainFeature, FALSE);


xfmFeature_savePreferenceProperties (gasMainFeature, L"placing");


// If auto-attributing after placement is on then activate Annotate method (if it exists)


xfmPropMgr_getPropertyBoolValue (&autoAttribute, L"SysProps/AutoAttribute", FALSE);


if (autoAttribute)


{


BoolInt annotateMethodExists=FALSE;


xfmCmdMgr_methodExists (&annotateMethodExists, L"GasMain", L"Annotate");


if (!annotateMethodExists)


{


placeGasMain_done();


return;


}


// --- set group to edit as required by annotate logic ---


xfmFeature_setFeatureGroup (gasMainFeature, L"edit");


// Since not opening edit box, initialize "editing" properties in case required for annotation


xfmFeature_initializeProperties (gasMainFeature, L"editing");


// --- set locatedFeatureRootName which is required by edit logic ---


xfmCmdMgr_setProperty (L"locatedFeatureRootName", L"GasMain");


xfmCmdMgr_setProperty (L"locatedFeatureGroupName", L"edit");


// --- start up the feature's Annotate Method ---


xfmCmdMgr_activateMethod (L"GasMain", L"Annotate");


return;


} 


placeGasMain_done();


}

Also of interest is this snippet from the XFM Standard Operations Library which will open the edit dialog box before annotation if system properties are set to do so.



/*


If "SysProps/AutoAttribute" == TRUE


If "SysProps/OpenEditDialogDuringAutoAttribution" == FALSE


start annotation placement (run "Annotate" method)


Else


open Edit box (run "Edit" method)


Else


restart current XFM command (placement)


*/


 


xfmPropMgr_getPropertyBoolValue (&autoAttribute, L"SysProps/AutoAttribute", FALSE);


if (autoAttribute) 


{


MSWChar* featureName=NULL;


MSWChar* featureAlias=NULL;


xfmCmdMgr_getProperty (&featureName, L"placementFeature");


xfmCmdMgr_getProperty (&featureAlias, L"placementAlias");


BoolInt annotateMethodExists=FALSE;


xfmCmdMgr_methodExists (&annotateMethodExists, featureName, L"Annotate");


BoolInt openEditBox = TRUE;


xfmPropMgr_getPropertyBoolValue (&openEditBox, L"SysProps/OpenEditDialogDuringAutoAttribution", FALSE);


if (openEditBox)


{


// --- check for Edit and Annotate Methods for current feature ---


BoolInt editMethodExists=FALSE;


xfmCmdMgr_methodExists (&editMethodExists, featureName, L"Edit");


if (annotateMethodExists && editMethodExists)


{


XfmFeatureP editFeature=NULL;


if (SUCCESS == xfmFeatureMgr_loadFeatureFromList (&editFeature, placementGroup, featureAlias))


{


// --- set group to edit as required by edit logic ---


xfmFeature_setFeatureGroup (editFeature, L"edit");


// --- set locatedFeatureRootName which is required by edit logic ---


xfmCmdMgr_setProperty (L"locatedFeatureRootName", featureAlias);


xfmCmdMgr_setProperty (L"locatedFeatureGroupName", L"edit");


// --- start up the feature's Edit Method ---


xfmCmdMgr_activateMethod (featureName, L"Edit");


if (NULL != featureOps)


dlmSystem_mdlFree (featureOps);


if (NULL != placementGroup)


dlmSystem_mdlFree (placementGroup);


if (NULL != featureName)


dlmSystem_mdlFree (featureName);


if (NULL != featureAlias)


dlmSystem_mdlFree (featureAlias);


if (NULL != editFeature)


xfmFeature_free (&editFeature);


return;


}


if (NULL != editFeature)


xfmFeature_free (&editFeature);


}


}


else


{


if (annotateMethodExists)


{


XfmFeatureP editFeature=NULL;


if (SUCCESS == xfmFeatureMgr_loadFeatureFromList (&editFeature, placementGroup, featureAlias))


{


// --- set group to edit as required by annotate logic ---


xfmFeature_setFeatureGroup (editFeature, L"edit");


// Since not opening edit box, initialize "editing" properties in case required for annotation


xfmFeature_initializeProperties (editFeature, L"editing");


// --- set locatedFeatureRootName which is required by edit logic ---


xfmCmdMgr_setProperty (L"locatedFeatureRootName", featureAlias);


xfmCmdMgr_setProperty (L"locatedFeatureGroupName", L"edit");


// --- start up the feature's Annotate Method ---


xfmCmdMgr_activateMethod (featureName, L"Annotate");


if (NULL != featureOps)


dlmSystem_mdlFree (featureOps);


if (NULL != placementGroup)


dlmSystem_mdlFree (placementGroup);


if (NULL != featureName)


dlmSystem_mdlFree (featureName);


if (NULL != featureAlias)


dlmSystem_mdlFree (featureAlias);


if (NULL != editFeature)


xfmFeature_free (&editFeature);


return;

xfmFeature_free (&editFeature);

Hello,

I have also used Place (MDL Handler) example command and created my own function inserting an ellipse element by two points.

This example shows how to create a feature, but I want to add an annotation text after that. How can I do it? How to complete my function to call annotation command?

Hello Mariusz,

Use the xfmPropMgr_getPropertyXXX functions to get an operation property value.

_{One another question...}

I have defined my command like in geo_example.xml Place(MDL) for GasMain feature.

How can I get an operation's property in MDL? I have one property defining width of buffer rectangle that I draw. And I want to catch it in MDL while creating a feature.

Chris,

I can always bank on you! Thanks a lot. These examples were very helpful for me.

Hello Myzzard,

In geo_example schema, take a look at the GasMain feature where there are a number of GasMain placement methods. See method "Place(MDL)" which starts keyin "place gasmain" when the method is activated. Also see method "Place(MDL Handler)" which is an example of a custom MDL procedure which uses the same setup as other XFM standard MDL procedures. The MDL source is in mdl\examples\gasmain\.

Chris
