Changing the physical description is necessary when the property value of an object changes.

We can handle varying window labels using regular expressions. WinRunner uses two hidden properties in order to use regular expression in an object’s physical description. These properties are regexp_label and regexp_MSW_class.

i. The regexp_label property is used for windows only. It operates behind the scenes to insert a regular expression into a window’s label description.

ii. The regexp_MSW_class property inserts a regular expression into an object’s MSW_class. It is obligatory for all types of windows and for the object class object.

The regexp_label property is used for windows only. It operates behind the scenes to insert a regular expression into a window’s label description.
The regexp_MSW_class property inserts a regular expression into an object’s MSW_class. It is obligatory for all types of windows and for the object class object.

We can suppress the regular expression of a window by replacing the regexp_label property with label property.

We can copy and move objects between different GUI Map files using the GUI Map Editor. The steps to be followed are:

1. Choose Tools - GUI Map Editor to open the GUI Map Editor.
2. Choose View - GUI Files.
3. Click Expand in the GUI Map Editor. The dialog box expands to display two GUI map files simultaneously.
4. View a different GUI map file on each side of the dialog box by clicking the file names in the GUI File lists.
5. In one file, select the objects you want to copy or move. Use the Shift key and or Control key to select multiple objects. To select all objects in a GUI map file, choose Edit - Select All.
6. Click Copy or Move.
7. To restore the GUI Map Editor to its original size, click Collapse.

Use the Shift key and or Control key to select multiple objects. To select all objects in a GUI map file, choose Edit - Select All.

We can clear a GUI Map file using the Clear All option in the GUI Map Editor.

GUI Map Editor has a Filter option. This provides for filtering with 3 different types of options.

1. Logical name displays only objects with the specified logical name.
2. Physical description displays only objects matching the specified physical description. Use any substring belonging to the physical description.
3. Class displays only objects of the specified class, such as all the push buttons.
