Detailed Description

Base class which defines methods common for all Nictk internal widgets (not windows nor menus).

It overrides the tkinter class.

Constructor & Destructor Documentation

__init__()

def __init__	(		self,
			parent,
			x,
			y,
			w,
			h,
			pad,
			ctor,
		**	kw
	)

The constructor.

Reimplemented in Canvas, Text, Notebook, HorFrame, VerFrame, RowFrame, VerScrollFrame, RowScrollFrame, Label, Button, Entry, Checkbutton, Radiobutton, Listbox, Combobox, Scale, and Spinbox.

Member Function Documentation

activate()

def activate

(

self

)

Sets the state of the widget to NORMAL.

The widget can interact with mouse and keyboard. If the widget is a container all its children are set to NORMAL.

deactivate()

def deactivate

(

self

)

Sets the state of the widget to DISABLED.

The widget is grayed and cannot interact with mouse and keyboard. If the widget is a container all its children are set to DISABLED.

destroy()

def destroy

(

self

)

Overrides the BaseWidget method, unmapping the widget if its parent is a _embedVerFrame.

So it triggers an <Unmap> event resizing the parent.

enabled()

def enabled

(

self

)

Returns True if the widget is enabled.

get_content()

def get_content

(

self

)

Returns the content of the widget as a string.

If the content is an image returns the string "image".

hide()

def hide

(

self

)

Hides the widget.

The widget will not be displayed, but its data remain managed; use show() to newly display it.

init_content()

def init_content	(		self,
			content
	)

Sets the content type for the widget.

The set_content() and get_content() methods will then behave according to the type chosen. The warious widget constructors call this, so the user needs to call this only when he sets for the first time the widget content (if he didn't already it in the constructor).

Parameters

content

can be a string, a StringVar or an image (BitmapImage, PhotoImage).

resize()

def resize	(		self,
			x = None,
			y = None,
			w = None,
			h = None,
			pad = None
	)

Changes the dimensions of the widget.

Only the given values are updated. Be careful, because if you have packed other widgets with respect to this their position will change.

set_content()

def set_content	(		self,
			content
	)

Sets the content of the widget.

Parameters

content

you must supply a content compatible with that given in init_content().

Reimplemented in Combobox.

show()

def show

(

self

)

Shows a previously hidden widget.

visible()

def visible

(

self

)

Returns True if the widget is visible.
