                  int height)
```
    Parameters:
    
    owner - the Frame this dialog will belong to
    
    strings - Strings resource to be used for text messages
    
    width - width of the original image, before cropping; this is used to determine the valid values for left and right column, from 0 to width - 1
    
    height - height of the original image, before cropping; this is used to determine the valid values for top and bottom row, from 0 to height - 1
- Method Detail
  - actionPerformed
```
public void actionPerformed(ActionEvent e)
```
    Hides (closes) this dialog if the OK button was source of the action event (e.g. if the button was pressed).
    
    Specified by:
    
    actionPerformed in interface ActionListener
  - getHeight
```
public int getHeight()
```
    Overrides:
    
    getHeight in class Component
  - getValue
```
private int getValue(TextComponent textField)
```
    Attempts to convert the content of the argument text component to an int; if successful, returns that int, otherwise -1 is returned.
    
    Parameters:
    
    textField - the text component that is supposed to hold an int value
    
    Returns:
    
    int representation of the text component's data
  - getWidth
```
public int getWidth()
```
    Returns the width of the to-be-cropped image as given by the current values in the text fields for left column and right column. Computes the width from those values and returns it or returns -1 if the data in the text fields is not valid for some reason.
    
    Overrides:
    
    getWidth in class Component
    
    Returns:
    
    width of cropped image or -1 if information is invalid

public int getY2()
```
  - hasPressedOk
```
public boolean hasPressedOk()
```
  - updateLabels

private void updateLabels()
```
    Computes width and height of new image and updates the corresponding labels. The labels will either display width and height or a single dash if the data in the text fields is invalid.
  - keyPressed
```
public void keyPressed(KeyEvent e)
```
    Specified by:
    
    keyPressed in interface KeyListener
  - keyReleased
```
public void keyReleased(KeyEvent e)
```
    Specified by:
    
    keyReleased in interface KeyListener
  - keyTyped
