Here’s a basic Python example that shows how to:

• Create a dynamic, on-the-fly custom property
• Add a grid to the PPG
• Set the PPG Logic in Python
• Select rows in a GridWidget

import win32com.client
from win32com.client import constants

oProp = Application.ActiveSceneRoot.AddProperty( "CustomProperty", False, "GridWidgetDemo" )
oProp.AddParameter2("Row",constants.siInt4,1,1,20,0,100,constants.siClassifUnknown,constants.siPersistable + constants.siKeyable)
			
oParameter = oProp.AddGridParameter( "DemoGrid" )
oGridData = oParameter.Value
oGridData.ColumnCount = 3
oGridData.RowCount = 20

for i in range(0,oGridData.RowCount):
	for j in range(0,oGridData.ColumnCount):
		oGridData.SetCell( j, i, str(i) + "." + str(j) )

oPPGLayout = oProp.PPGLayout
oGridPPGItem = oPPGLayout.AddItem( "DemoGrid" )

oGridPPGItem.SetAttribute( constants.siUINoLabel, True )
oGridPPGItem.SetAttribute( constants.siUIGridSelectionMode, constants.siSelectionHeader )
oGridPPGItem.SetAttribute( constants.siUIGridColumnWidths, "25:100:75:100" )
oGridPPGItem.SetAttribute( constants.siUIGridReadOnlyColumns, "1" )

oPPGLayout.AddRow() ;
oPPGLayout.AddItem( "Row" )
oPPGLayout.AddButton( "SelectRow", "Select Row" )
oPPGLayout.EndRow()



oPPGLayout.Language = "Python"
oPPGLayout.Logic = '''
def SelectRow_OnClicked():
	Application.LogMessage( "Select Row" )
	oGridData = PPG.DemoGrid.Value
	oGridWidget = oGridData.GridWidget
	oGridWidget.ClearSelection()
	oGridWidget.AddToSelection( -1, PPG.Row.Value-1 )
'''


Application.InspectObj( oProp )
