Method Detail

show

java.lang.Object show()

Displays the popup dialog window. If the dialog is modal then this method blocks until the dialog is dismissed by the user or the 'close()' method is called.

Returns:

The Object chosen by the user (UNINITIALIZED_VALUE if the user has not yet made a choice, or null if the user closed the window without making a choice) or the value entered via the 'close()' method.

showAndWait

java.lang.Object showAndWait()

Displays the popup dialog window. The method blocks until the dialog is dismissed by the user or the 'close()' method is called (even if the window is non-modal).

Returns:

The Object chosen by the user (UNINITIALIZED_VALUE if the user has not yet made a choice, or null if the user closed the window without making a choice) or the value entered via the 'close()' method.

setVisible

void setVisible(boolean flgVal)

Sets the visibility of the dialog window. If the dialog is non-modal then the call is redirected to the dialog object's 'show()' or 'hide()' method (depending on the state of the given flag parameter).

Parameters:

flgVal - true for visible, false for hidden.

setVisibleViaInvokeLater

void setVisibleViaInvokeLater(boolean flgVal)

Sets the visibility of the dialog window, using the event-dispatch thread via a call to 'SwingUtilities.invokeLater()'. This allows a modal dialog to be shown without blocking the invoking thread.

Parameters:

flgVal - true for visible, false for hidden.

isVisible

boolean isVisible()

Determines whether the popup dialog should be visible when its parent is visible.

Returns:

true if the popup dialog is visible; false otherwise.

isShowing

boolean isShowing()

Returns true if the popup dialog window is showing.

Returns:

true if the popup dialog window is showing, false if not.

waitForDialogVisible

boolean waitForDialogVisible(int maxWaitTimeMs)

Waits for the popup dialog window to be visible, up to the given maximum time value.

Parameters:

maxWaitTimeMs - the maximum time to wait, in milliseconds.

Returns:

true if the dialog is visible, false if the maximum time was reached without the dialog being visible.

close

void close(java.lang.Object obj)

Closes the popup dialog window.

Parameters:

obj - the value to be returned via the 'show()' or 'showAndWait()' method.
