Create a new Widget with a handle to a native resource returned from a call to the native libraries.
Parameters:
handle - The handle that represents a pointer to a native resource.

                           int accelKey,
                           ModifierType accelMods,
                           AccelFlags accelFlags)

addListener

public void addListener(KeyListener listener)

An important thing to notice is that some widgets don't receive low-level events (such as a key-press event) by default. So if you want to capture events from them, you should add them to an EventBox, and capture events on the EventBox.

The reason why this happens is that some widgets, for efficiency, don't have their own X window, which is necessary to receive events. These are the widgets that don't have their own X window:

Alignment
Arrow
Bin
Box
Image
Item
Label
Pixmap
ScrolledWindow
Separator
Table
AspectFrame
Frame
VBox
HBox
VSeparator
HSeparator

Parameters:
listener - The object that has implemented the KeyListener interface that is to receive the key events.

public void addListener(LifeCycleListener listener)
Register an object to receive life cycle event notification.
Parameters:
listener - The object that has implemented the LifeCycleListener interface that is to receive the life cycle events.

addListener

public void addListener(MouseListener listener)
Register an object to receive mouse event notification.

An important thing to notice is that some widgets don't receive low-level events (such as a mouse-click event) by default. So if you want to capture events from them, you should add them to an EventBox, and capture events on the EventBox.

The reason why this happens is that some widgets, for efficiency, don't have their own X window, which is necessary to receive events. These are the widgets that don't have their own X window:

listener - The object that has implemented the MouseListener interface that is to receive the mouse events.

addListener

public void addListener(MouseMotionListener listener)

An important thing to notice is that some widgets don't receive low-level events (such as a mouse-enter event) by default. So if you want to capture events from them, you should add them to an EventBox, and capture events on the EventBox.

The reason why this happens is that some widgets, for efficiency, don't have their own X window, which is necessary to receive events. These are the widgets that don't have their own X window:

Sets the background color for a widget in a particular state. All other style values are left untouched.

Note that some widgets draw on their parent container's window and thus may not draw any background themselves. This is the case for e.g. Label. To modify the background of such widgets, you have to set the background color on their parent; if you want to set the background of a rectangular area around a label, try placing the label in an EventBox widget and setting the background color on that

Parameters:

                         Color color)

                          TargetEntry[] targets,
                          DragAction actions)
Sets up the widget so that it can be the source of drag and drop operations.
Parameters:
buttons - Buttons which can start the drag
targets - An array of names of drag and drop operations accepted (these are made up by the application designers. Widgets must set as drag sources and destinations with one of these the same)
actions - Drag action - determines which events will be called.

setEvents

public void setEvents(EventMask events)
Sets the event mask for a widget. The event mask determines which events a widget will receive. Keep in mind that different widgets have different default event masks, and by changing the event mask you may disrupt a widget's functionality, so be careful. This function must be called while a widget is unrealized. Consider addEvents() for widgets that are already realized, or if you want to preserve the existing event mask. This function can't be used with NO_WINDOW widgets; to get events on those widgets, place them inside an EventBox and receive events on the event box.
Parameters:
events -

setExtensionEvents

public void setExtensionEvents(ExtensionMode mode)
Sets the extension events mask to mode.
Parameters:
mode - extension events to receive.

setFont

public void setFont(FontDescription fontDesc)
Sets the font to use for the widget.
Parameters:
fontDesc - The font description to use.

setForegroundColor

public void setForegroundColor(StateType state,
                               Color color)
Sets the foreground color for a widget in a particular state. All other style values are left untouched.
Parameters:
state - The widget state to modify.
color - The color to set the foreground.

setMinimumSize

public void setMinimumSize(int width,
                           int height)
Sets the minimum size of a widget. You can use this method to force a widget to be either larger or smaller that it normally be.

In most cases Window.setDefaultSize() is a better choice for toplevel windows than this method. Setting the default size will still allow users to shrink the window. Setting the minimum size will force them to leave the window at least as large as the request.

Note the inherent danger of setting any fixed size - themes, translations into other languages, different fonts, and user action can change the appropriate size for a given widget. So, it's basically impossible to hardcode a size that will always be correct.

If the minimum size in a given direction is -1 then the "natural" size for the widget will be used instead.

Parameters:
width - The minimum width size to use.
height - The minimum height size to use.

setName

public void setName(String name)
Sets the name for this widget. Widgets can be named which allows you to refer to them from a gtkrc file. You can apply a style to widgets with a particular name in the gtkrc file. Names are also useful in accessibility contexts (ie, using ATK) to dig into a runnnig Window and extract a specific Widget (the concept is analoguous to id attributes in XML)
Parameters:
name - The name for the widget.

setNoDragDestination

public void setNoDragDestination()
Removes support for this widget being a drag and drop target

setNoDragSource

public void setNoDragSource()
Removes support for this widget being a drag and drop source.

setSensitive

public void setSensitive(boolean sensitive)
Sets the sensitivity of a widget. A widget is sensitive if the user can interact with it. Insensitive widgets are "grayed out" and the user can't interact with them. Insensitive widgets are known as "inactive", "disabled", or "ghosted" in some other toolkits.
Parameters:
sensitive - true to make the widget sensitive.

setTextColor

public void setTextColor(StateType state,
                         Color color)
Sets the text color for a widget in a particular state. All other style values are left untouched. The text color is the foreground color along with the base color for widgets such as Entry, TextView, etc.

Note that some widgets draw on their parent container's window and thus may not draw any background themselves. This is the case for e.g. Label. To modify the background of such widgets, you have to set the background color on their parent; if you want to set the background of a rectangular area around a label, try placing the label in an EventBox widget and setting the background color on that

Parameters:
state - The widget state to modify.
color - The color to set the text.

shapeCombineMask

public void shapeCombineMask(Bitmap shapeMask,
                             int x,
                             int y)
Sets the shape of this widgets OS window. This allows for transparent windows.
