Summary:

I am trying to set the column width of the "Object Tree" column so that I do not need to manually resize it every time I view my Process Analyst page in runtime.  My trend tag names are quite long and I cannot distinguish them, as their names are cut.

However, in design time, the Process Analyst properties do not list that specific column. So I cannot statically set its width to my desired value.

Any work around?

 

Solution:

In runtime, you can dynamically set the column width as soon as the Process Analyst page is shown. This would appear seemless to the user. Practically, you would need to call a cicode function on a "On Page Shown" event:

 

The SetColumnSize function is defined as follows:

 

FUNCTION SetColumSize(STRING sPaObjectName, STRING sColumnName, INT iWidth)

OBJECT hPA;

OBJECT hObjectView;

OBJECT hColumns;

OBJECT hColumn;

hPA = ObjectByName(sPaObjectName);

hObjectView= _ObjectGetProperty(hPA, "ObjectView");

hColumns= _ObjectGetProperty(hObjectView, "Columns")

hColumn= _ObjectCallMethod(hColumns, "get_ItemByName", sColumnName)

_ObjectSetProperty(hColumn, "Width", iWidth);

iWidth;sColumnName;sPaObjectName;sPaObjectName;

END

 

 

Note1: If you are unsure of the column name, you can call the following cicode function to return the column name and its current size:

 

FUNCTION GetColumnNameAndSize(STRING sPaObjectName)

OBJECT hPA;

OBJECT hObjectView;

OBJECT hColumns;

OBJECT hColumn;

INT iIdx, iWidth;

STRING sColumnName

 

iIdx=Input("Which column?", "Enter a column index:","1")

hPA = ObjectByName(sPaObjectName);

hObjectView= _ObjectGetProperty(hPA, "ObjectView");

hColumns= _ObjectGetProperty(hObjectView, "Columns")

hColumn = _ObjectCallMethod(hColumns, "get_Item", iIdx);

sColumnName= _ObjectGetProperty(hColumn, "Name");

iWidth= _ObjectGetProperty(hColumn, "Width");

Message("","Column "+sColumnName+sColumnName" has a size of "+iWidth:####,iWidth####1)

;;iIdx;;sPaObjectName;

END

 

 

Note2: you may also set the column size only once, by using the "persist ActiveX Data between page transitions", described in the help as follows:

"

Select this check box to allow changes made to the control to be persisted between pages. For example, you can select this check box if you want an ActiveX edit control to keep the current text in the control, so that next time the page is entered, the same text is displayed.

The data is only persisted for that session. If CitectSCADA runtime is shut down and restarted, the updated data is not available.

"
