Constructor Details

RunClearBreakpointsAction

public RunClearBreakpointsAction(String name,
 Icon icon,
 String descrip,
 Integer mnemonic,
 KeyStroke accel,
 VenusUI gui)

Create the object and register with text segment window as a listener on its table model. The table model has not been created yet, so text segment window will hang onto this registration info and transfer it to the table model upon creation (which happens with each successful assembly).

Method Details

actionPerformed

public void actionPerformed(ActionEvent e)

When this option is selected, tell text segment window to clear breakpoints in its table model.

Specified by:

actionPerformed in interface ActionListener

Overrides:

actionPerformed in class GuiAction

tableChanged

public void tableChanged(TableModelEvent e)

Required TableModelListener method. This is response upon editing of text segment table model. The only editable column is breakpoints so this method is called only when user adds or removes a breakpoint. Gets new breakpoint count and sets enabled status accordingly.

Specified by:

tableChanged in interface TableModelListener
