Returns:
true if the user can resize this frame; false otherwise.
See Also:

setResizable

public void setResizable(boolean resizable)
Enabled: Sets whether this frame is resizable by the user.

Parameters:
resizable - true if this frame is resizable; false otherwise.
See Also:
java.awt.Frame#isResizable

setState

public void setState(int state)
Suppressed: Sets the state of this frame (obsolete).

In older versions of JDK a frame state could only be NORMAL or ICONIFIED. Since JDK 1.4 set of supported frame states is expanded and frame state is represented as a bitwise mask.

For compatibility with old programs this method still accepts Frame.NORMAL and Frame.ICONIFIED but it only changes the iconic state of the frame, other aspects of frame state are not affected by this method.

Parameters:
state - either Frame.NORMAL or Frame.ICONIFIED.
See Also:
getState(), setExtendedState(int)

setExtendedState

public void setExtendedState(int state)
Enabled: Sets the state of this frame. The state is represented as a bitwise mask.

Note that if the state is not supported on a given platform, nothing will happen. The application may determine if a specific state is available via the java.awt.Toolkit#isFrameStateSupported(int state) method.

Parameters:
state - a bitwise mask of frame state constants
Since:
1.4
See Also:
getExtendedState(), java.awt.Toolkit#isFrameStateSupported(int)

getState

public int getState()
Suppressed: Gets the state of this frame (obsolete).

In older versions of JDK a frame state could only be NORMAL or ICONIFIED. Since JDK 1.4 set of supported frame states is expanded and frame state is represented as a bitwise mask.

For compatibility with old programs this method still returns Frame.NORMAL and Frame.ICONIFIED but it only reports the iconic state of the frame, other aspects of frame state are not reported by this method.

Returns:
Frame.NORMAL or Frame.ICONIFIED.
See Also:
setState(int), getExtendedState()

getExtendedState

public int getExtendedState()
Enabled: Gets the state of this frame. The state is represented as a bitwise mask.

Returns:
a bitwise mask of frame state constants
Since:
1.4
See Also:
setExtendedState(int)

setMaximizedBounds

public void setMaximizedBounds(Rectangle bounds)
Enabled: Sets the maximized bounds for this frame.

When a frame is in maximized state the system supplies some defaults bounds. This method allows some or all of those system supplied values to be overridden.

If bounds is null, accept bounds supplied by the system. If non-null you can override some of the system supplied values while accepting others by setting those fields you want to accept from system to Integer.MAX_VALUE.

On some systems only the size portion of the bounds is taken into account.

Parameters:
bounds - bounds for the maximized state
Since:
1.4
See Also:
getMaximizedBounds

getMaximizedBounds

public Rectangle getMaximizedBounds()
Enabled: Gets maximized bounds for this frame. Some fields may contain Integer.MAX_VALUE to indicate that system supplied values for this field must be used.

Returns:
maximized bounds for this frame; may be null
Since:
1.4
See Also:
setMaximizedBounds(Rectangle)

setUndecorated

public void setUndecorated(boolean undecorated)

removeNotify

public void removeNotify()
Suppressed: Makes this Frame undisplayable by removing its connection to its native screen resource. Making a Frame undisplayable will cause any of its children to be made undisplayable. This method is called by the toolkit internally and should not be called directly by programs.
