"If ColumnNumber is omitted or is larger than the number of columns currently in the control, the new column is added next to the last column on the right side."
Example:
Code: Select all
g := gui(), LV := g.add("listview")
LV.insertCol(,,1)
LV.insertCol(,,2)
LV.insertCol(,,3)
LV.ModifyCol()
g.show
