Class dPemMixin

Specifies the platform-native font info string. Read-only. (str)
Specifies whether font is italicized. (bool)
Specifies the point size of the font. (int)

window. (str)

When True, Mouse Enter events fire the onHover method, and

Specifies the left position of the object. (int)
Specifies which events to log.  (list of strings)

If the first element is 'All', all events except the following listed events
will be logged.
Event logging is resource-intensive, so in addition to setting this LogEvents
property, you also need to make the following call:

	>>> dabo.eventLogging = True

Maximum allowable height for the control in pixels.  (int)
Maximum allowable size for the control in pixels.  (2-tuple of int)
Maximum allowable width for the control in pixels.  (int)
Minimum allowable height for the control in pixels.  (int)
Minimum allowable size for the control in pixels.  (2-tuple of int)
Minimum allowable width for the control in pixels.  (int)
Specifies the shape of the mouse pointer when it enters this window. (obj)
Specifies the name of the object, which must be unique among siblings.

If the specified name isn't unique, an exception will be raised. See also
NameBase, which let's you set a base name and Dabo will automatically append
integers to make it unique.

Specifies the base name of the object.

The base name specified will become the object's Name, unless another sibling
already has that name, in which case Dabo will find the next unique name by
adding integers to the end of the base name. For example, if your code says:

	self.NameBase = "txtAddress"

and there is already a sibling object with that name, your object will end up
with Name = "txtAddress1".

This property is write-only at runtime.

The containing object. (obj)
The (x,y) position of the object. (tuple)
Reference to the Preference Management object  (dPref)
A unique identifier used for referencing by other objects. (str)
The position of the right side of the object. This is a
convenience property, and is equivalent to setting the Left property
to this value minus the Width of the control.  (int)
The size of the object. (tuple)
The sizer for the object.
Specifies the text that displays in the form's status bar, if any.

The text will appear when the control gets the focus, or when the
mouse hovers over the control, and will clear when the control loses
the focus, or when the mouse is no longer hovering.

For forms, set StatusText whenever you want to display a message.

A property that user code can safely use for specific purposes.
Specifies the tooltip text associated with this window. (str)
The top position of the object. (int)
Transparency level of the control; ranges from 0 (transparent) to 255 (opaque).
Default=0. Does not currently work on Gtk/Linux.  (int)

Time in seconds to change transparency. Set it to zero to see instant changes.
Default=0.25 (float)

Specifies whether the object is visible at runtime.  (bool)
Specifies whether the object is physically visible at runtime.  (bool)

The Visible property could return True even if the object isn't actually
shown on screen, due to a parent object or sizer being invisible.

The VisibleOnScreen property will return True only if the object and all
parents are visible.

The width of the object. (int)
The platform-specific handle for the window. Read-only. (long)

This is a good place to put redraw or other such UI-intensive code, so that it
will only run when the application is otherwise not busy doing other (more
important) things.

Occurs when a key is depressed and released on the
focused control or form.

Occurs when any key is depressed on the focused control or form.

Occurs when any key is released on the focused control or form.

and released on the control.

Occurs when the mouse's left button is released on the control.
Occurs when the mouse mouse's middle button is depressed
and released on the control.

Occurs when the mouse's middle button is double-clicked
on the control.

Occurs when the mouse's middle button is depressed on the control.
Occurs when the mouse's middle button is released on the control.
Occurs when the mouse moves in the control.
Occurs when the mouse mouse's right button is depressed
and released on the control.

Occurs when the mouse's right button is double-clicked on the control.
Occurs when the mouse's right button is depressed on the control.

Occurs when the control's position changes.
Occurs when it is time to paint the control.
Occurs when the control or form is resized.
Occurs when a drag operation begins in a tree.
Occurs when a drag operation ends in a tree.
Occurs when a container wants its controls to update
their properties.

Translates a position value for a control to absolute screen position.
Instantiate object as a child of self.

The classRef argument must be a Dabo UI class definition. (it must inherit
dPemMixin). Alternatively, it can be a saved class definition in XML format,
as created by the Class Designer.

The name argument, if passed, will be sent along to the object's
constructor, which will attempt to set its Name accordingly. If the name
argument is not passed (or None), the object will get a default Name as
defined in the object's class definition.

Additional positional and/or keyword arguments will be sent along to the
object's constructor.

Subclass hook. Called after the object's __init__ has run fully.
Subclasses should place their __init__ code here in this hook, instead of
overriding __init__ directly, to avoid conflicting with base Dabo behavior.

Automatically bind any on*() methods to the associated event.

User code only needs to define the callback, and Dabo will automatically
set up the event binding. This will satisfy lots of common cases where
you want an object or its parent to respond to the object's events.

To use this feature, just define a method on<EventName>(), or	if you
want a parent container to respond to the event, make a method in the
parent on<EventName>_<object Name or RegID>().

For example::

	class MyButton(dabo.ui.dButton):
		def onHit(self, evt):
			print "Hit!"

	class MyPanel(dabo.ui.dPanel):
		def afterInit(self):
			self.addObject(MyButton, RegID="btn1")

		def onHit_btn1(self, evt):
			print "panel: button hit!"

When the button is pressed, you'll see both 'hit' messages because of
auto event binding.

If you want to bind your events explicitly, you can turn off auto event
binding by calling::

	 dabo.autoBindEvents = False

This feature is inspired by PythonCard.

Subclass hook. Called before the object is fully instantiated.
Usually, user code should override afterInit() instead, but there may be
cases where you need to set an attribute before the init stage is fully
underway.

Bind a dEvent to a callback function.
Bind a sequence of [dEvent, callback] lists.
Bind a key combination such as "ctrl+c" to a callback function.

See dKeys.keyStrings for the valid string key codes.
See dKeys.modifierStrings for the valid modifier codes.

Examples::

	# When user presses <esc>, close the form:
	form.bindKey("esc", form.Close)

	# When user presses <ctrl><alt><w>, close the form:
	form.bindKey("ctrl+alt+w", form.Close)

Makes this object topmost
Clears the background of custom-drawn objects.
Create another object just like the passed object. It assumes that the
calling object will be the container of the newly created object.

Given a position relative to this control, return a position relative
to the specified container. If no position is passed, returns the position
of this control relative to the container.

Called by uiApp when the user requests a copy operation.

Return None (the default) and uiApp will try a default copy operation.
Return anything other than None and uiApp will assume that the copy
operation has been handled.

Called by uiApp when the user requests a cut operation.

Return None (the default) and uiApp will try a default cut operation.
Return anything other than None and uiApp will assume that the cut
operation has been handled.

Draws an arc (pie slice) of a circle centered around the specified point,
starting from 'startAngle' degrees, and sweeping counter-clockwise
until 'endAngle' is reached.
