Description

gtk.Paned is the base class for widgets with two panes, arranged either horizontally (gtk.HPaned) or vertically (gtk.VPaned). Child widgets are added to the panes of the widget with the pack1() and pack2() methods. The division between the two children is set by default from the size requests of the children, but it can be adjusted by the user.

A paned widget draws a separator between the two child widgets and a small handle that the user can drag to adjust the division. It does not draw any relief around the children or around the separator. (The space in which the separator located is called the gutter.) Often, it is useful to put each child inside a gtk.Frame with the shadow type set to gtk.SHADOW_IN so that the gutter appears as a ridge.

Each child has two options that can be set, resize and shrink. If resize is True, when the gtk.Paned is resized, that child will expand or shrink along with the paned widget. If shrink is True, the child can be made smaller than it's requisition. Setting shrink to False allows the application to set a minimum size. If resize is False for both children, the resizing behaves as if resize is True for both children. The application can set the position of the slider by calling the set_position() method.

Methods

gtk.Paned.add1

    def add1(child)

child :

the widget to add

The add1() method adds the widget specified by child to the top or left pane with the default packing parameters (resize is False and shrink is True). See the pack1() method.

gtk.Paned.add2

    def add2(child)

child :

the widget to add

The add2() method adds the widget specified by child to the bottom or right pane with the default packing parameters (resize is True and shrink is True). See the pack2() method.

gtk.Paned.pack1

    def pack1(child, resize=False, shrink=True)

child :

the widget to add

resize :

if True child should resize when the paned is resized

shrink :

if True child can be made smaller than its minimum size request

The pack1() method adds the widget specified by child to the top or left pane with the parameters specified by resize and shrink. If resize is True child should be resized when the paned widget is resized. If shrink is True child can be made smaller than its minimum size request.

gtk.Paned.pack2

    def pack2(child, resize=True, shrink=True)

child :

the widget to add

resize :

if True child should resize when the paned is resized

shrink :

if True child can be made smaller than its minimum size request

The pack2() method adds the widget specified by child to the bottom or right pane with the parameters specified by resize and shrink. If resize is True child should be resized when the paned widget is resized. If shrink is True child can be made smaller than its minimum size request.

gtk.Paned.get_position

    def get_position()

Returns :

the position of the divider

The get_position() method returns the position of the divider in pixels between the two panes.

gtk.Paned.set_position

    def set_position(position)

position :

the new pixel position of divider, a negative value means that the position is unset.

The set_position() method sets the position of the divider between the two panes to the value specified by position and sets the "position-set" property to True if position is non-negative. If position is negative the divider position will be recalculated by the paned widget using the child widget requisitions and the "position-set" property will be set to False.

gtk.Paned.compute_position

    def compute_position(allocation, child1_req, child2_req)

allocation :

the total space allocation in pixels for the paned widget

child1_req :

the minimum space in pixels required for the left or top child widget

child2_req :

the minimum space in pixels required for the right or bottom child widget

The compute_position() method computes the position of the separator according to the specification of the parameters: allocation, child1_req and child2_req. The calculation is affected by the packing parameters of the child widgets depending on whether they can resize and shrink. This method is used by subclasses of gtk.Paned and is usually not needed by applications. the gtk.Widget.queue_resize() method must be called after this method to have the resizing displayed.

The minimum position is 0 if child1's shrink value is True or the value of child1_req, if False. The maximum position is the value of allocation if child2's shrink value is True, or the value of (allocation - child2_req), if False. The final calculated position will be between the minimum and maximum positions.

gtk.Paned.get_child1

    def get_child1()

Returns :

the first child, orNone

Note

This method is available in PyGTK 2.4 and above.

The get_child1() method returns the first child of the paned widget.

gtk.Paned.get_child2

    def get_child2()

Returns :

the second child, or None

Note

This method is available in PyGTK 2.4 and above.

The get_child2() method returns the second child of the paned widget.

Signals

The "accept-position" gtk.Paned Signal

    def callback(paned, user_param1, ...)

paned :

the paned that received the signal

user_param1 :

the first user parameter (if any) specified with the connect() method

... :

additional user parameters (if any)

Returns :

True if the signal was handled

The "accept-position" signal is emitted when paned has the focus and any of the Return, Enter, Space keys are pressed. This will also cause the child widget with the focus to be activated.

The "cancel-position" gtk.Paned Signal

    def callback(paned, user_param1, ...)

paned :

the paned that received the signal

user_param1 :

the first user parameter (if any) specified with the connect() method

... :

additional user parameters (if any)

Returns :

True if the signal was handled

The "cancel-position" signal is emitted when the Esc key is pressed while paned has the focus.

The "cycle-child-focus" gtk.Paned Signal

    def callback(paned, reversed, user_param1, ...)

paned :

the paned that received the signal

reversed :

if True the focus cycle direction should be reversed

user_param1 :

the first user parameter (if any) specified with the connect() method

... :

additional user parameters (if any)

Returns :

True if the signal was handled

The "cycle-child-focus" signal is emitted when F6 or Shift+F6 is pressed while paned has the focus.

The "cycle-handle-focus" gtk.Paned Signal

    def callback(paned, reversed, user_param1, ...)

paned :

the paned that received the signal

reversed :

if True the focus cycle direction should be reversed

user_param1 :

the first user parameter (if any) specified with the connect() method

... :

additional user parameters (if any)

Returns :

True if the signal was handled

The "cycle-handle-focus" signal is emitted when paned has the focus and any of the Tab, Ctrl+Tab, Shift+Tab or Ctrl+Shift+Tab keys combinations are pressed. Tab and Ctrl+Tab set reversed to False while Shift+Tab and Ctrl+Shift+Tab set reversed to True.

The "move-handle" gtk.Paned Signal

    def callback(paned, scrolltype, user_param1, ...)

paned :

the paned that received the signal

scrolltype :

the scroll type: gtk.SCROLL_NONE, gtk.SCROLL_JUMP, gtk.SCROLL_STEP_BACKWARD, gtk.SCROLL_STEP_FORWARD, gtk.SCROLL_PAGE_BACKWARD, gtk.SCROLL_PAGE_FORWARD, gtk.SCROLL_STEP_UP, gtk.SCROLL_STEP_DOWN, gtk.SCROLL_PAGE_UP, gtk.SCROLL_PAGE_DOWN, gtk.SCROLL_STEP_LEFT, gtk.SCROLL_STEP_RIGHT, gtk.SCROLL_PAGE_LEFT, gtk.SCROLL_PAGE_RIGHT, gtk.SCROLL_START or gtk.SCROLL_END

user_param1 :

the first user parameter (if any) specified with the connect() method

... :

additional user parameters (if any)

Returns :

True if the signal was handled

The "move-handle" signal is emitted when paned has the focus and one of the following key combinations is pressed to move the separator:

  • Left Arrow
  • Right Arrow
  • Up Arrow
  • Down Arrow
  • Page Up
  • Page Down
  • Home

The value of scrolltype is one of: gtk.SCROLL_NONE, gtk.SCROLL_JUMP, gtk.SCROLL_STEP_BACKWARD, gtk.SCROLL_STEP_FORWARD, gtk.SCROLL_PAGE_BACKWARD, gtk.SCROLL_PAGE_FORWARD, gtk.SCROLL_STEP_UP, gtk.SCROLL_STEP_DOWN, gtk.SCROLL_PAGE_UP, gtk.SCROLL_PAGE_DOWN, gtk.SCROLL_STEP_LEFT, gtk.SCROLL_STEP_RIGHT, gtk.SCROLL_PAGE_LEFT, gtk.SCROLL_PAGE_RIGHT, gtk.SCROLL_START or gtk.SCROLL_END. The default handler for this signal moves the separator if the separator has the focus.

The "toggle-handle-focus" gtk.Paned Signal

    def callback(paned, user_param1, ...)

paned :

the paned that received the signal

user_param1 :

the first user parameter (if any) specified with the connect() method
