| Constructor |
ShapeFormatAction(DialogOfShapeFormat dialog)
Sets the parameter to the field. |
|
actionPerformed
|
public void actionPerformed(ActionEvent e)
(1) If the "pixel" or "mm" button (Figure 1.1 (a)) is pressed, then calls the showLine or showRectangular method of the DialogOfShapeFormat to display the values to the spinners in the specified unit of length.
(2) If a check box on the property panel (Figure 1.3) is clicked, then handles as follows.
If the selected value of the check box is other than
the default value, then writes it to the selected shape (shapeContainer) by the next setProperty method.
Additionally, sets "on" or "off" (setSelected(true)
or setSelected(false)) to other properties according to the relations between
properties and changes spinners' state enable or disables (setEnabled(true)
or setEnabled(false)). For examples, when the "enable
resizing" property is changed to "off", then changes the states of
other check boxes and spinners as follows.
① Sets "off" (setSelected(false)) to the ratioBox and directionBox and disable them (setEnabled(false)).
② If the selected shape (shapeContainer) is a line, then disables the lineSpinners, and if it is not a line, then disables the sizeSpinners.
=> User's Guide The property of a shape and the spinners' values
(3) If the "OK" button (Figure 1.3) in the property tab is pressed, then sets the selected properties are
set to the shapeContainer and calls the closedDialog method to close the dialog.
(4) If the "Cancel" button (Figure 1.3) in the property tab is pressed, then calls the closedDialog method to close the dialog.
(5) If the OK button (Figure 1.5) on the text box tab is pressed, then generates the "TEXTBOX_LAYOUT"
command and calls exec method of the ExecCommand. Finally calls the closedDialog method.
(6) If the "Cancel" button (Figure 1.5) on the text box tab is pressed, then calls the closedDialog method.
