Sets our main struct and passes it to the parent class
Used to create a new table widget. An initial size must be given by specifying how many rows and columns the table should have, although this can be changed later with gtk_table_resize(). rows and columns must both be in the range 0 .. 65535.
Attach a new widget creating a new row if necessary
Warning gtk_table_attach has been deprecated since version 3.4 and should not be used in newly-written code. Use gtk_grid_attach() with GtkGrid. Note that the attach arguments differ between those two functions. Adds a widget to a table. The number of 'cells' that a widget will occupy is specified by left_attach, right_attach, top_attach and bottom_attach. These each represent the leftmost, rightmost, uppermost and lowest column and row numbers of the table. (Columns and rows are indexed from zero). To make a button occupy the lower right cell of a 2x2 table, use If you want to make the button span the entire bottom row, use left_attach == 0 and right_attach = 2 instead.

Removes all widgets from the container
Adds widget to container. Typically used for simple containers such as GtkWindow, GtkFrame, or GtkButton; for more complicated layout containers such as GtkBox or GtkGrid, this function will pick default packing parameters that may not be correct. So consider functions such as gtk_box_pack_start() and gtk_grid_attach() as an alternative to gtk_container_add() in those cases. A widget may be added to only one container at a time; you can't place the same widget inside two different containers.
Removes widget from container. widget must be inside container. Note that container will own a reference to widget, and that this may be the last reference held; so removing a widget from its container can destroy that widget. If you want to use widget again, you need to add a reference to it while it's not inside a container, using g_object_ref(). If you don't want to use widget again it's usually more efficient to simply destroy it directly using gtk_widget_destroy() since this will remove it from the container and help break any circular reference count cycles.
Returns the resize mode for the container. See gtk_container_set_resize_mode().
Sets the resize mode for the container. The resize mode of a container determines whether a resize request will be passed to the container's parent, queued for later execution or executed immediately.
Invokes callback on each non-internal child of container. See gtk_container_forall() for details on what constitutes an "internal" child. Most applications should use gtk_container_foreach(), rather than gtk_container_forall().
Returns the container's non-internal children. See gtk_container_forall() for details on what constitutes an "internal" child.
Returns a newly created widget path representing all the widget hierarchy from the toplevel down to and including child.
Sets the reallocate_redraws flag of the container to the given value. Containers requesting reallocation redraws get automatically redrawn if any of their children changed allocation.
Returns the current focus child widget inside container. This is not the currently focused widget. That can be obtained by calling gtk_window_get_focus(). Since 2.14
Sets, or unsets if child is NULL, the focused child of container. This function emits the GtkContainer::set_focus_child signal of container. Implementations of GtkContainer can override the default behaviour by overriding the class closure of this signal. This is function is mostly meant to be used by widgets. Applications can use gtk_widget_grab_focus() to manualy set the focus to a specific widget.
Retrieves the vertical focus adjustment for the container. See gtk_container_set_focus_vadjustment().
Hooks up an adjustment to focus handling in a container, so when a child of the container is focused, the adjustment is scrolled to show that widget. This function sets the vertical alignment. See gtk_scrolled_window_get_vadjustment() for a typical way of obtaining the adjustment and gtk_container_set_focus_hadjustment() for setting the horizontal adjustment. The adjustments have to be in pixel units and in the same coordinate system as the allocation for immediate children of the container.
Retrieves the horizontal focus adjustment for the container. See gtk_container_set_focus_hadjustment().
Hooks up an adjustment to focus handling in a container, so when a child of the container is focused, the adjustment is scrolled to show that widget. This function sets the horizontal alignment. See gtk_scrolled_window_get_hadjustment() for a typical way of obtaining the adjustment and gtk_container_set_focus_vadjustment() for setting the vertical adjustment. The adjustments have to be in pixel units and in the same coordinate system as the allocation for immediate children of the container.
Warning gtk_container_resize_children is deprecated and should not be used in newly-written code. 3.10
Returns the type of the children supported by the container. Note that this may return G_TYPE_NONE to indicate that no more children can be added, e.g. for a GtkPaned which already has two children.
Gets the value of a child property for child and container.
Sets a child property for child and container.
Gets the values of one or more child properties for child and container.
Sets one or more child properties for child and container.
Emits a "child-notify" signal for the child property child_property on widget. This is an analogue of g_object_notify() for child properties. Also see gtk_widget_child_notify().
Invokes callback on each child of container, including children that are considered "internal" (implementation details of the container). "Internal" children generally weren't added by the user of the container, but were added by the container implementation itself. Most applications should use gtk_container_foreach(), rather than gtk_container_forall(). Virtual: forall
Retrieves the border width of the container. See gtk_container_set_border_width().
Sets the border width of the container. The border width of a container is the amount of space to leave around the outside of the container. The only exception to this is GtkWindow; because toplevel windows can't leave space outside, they leave the space inside. The border is added on all sides of the container. To add space to only one side, one approach is to create a GtkAlignment widget, call gtk_widget_set_size_request() to give it a size, and place it on the side of the container as a spacer.
When a container receives a call to the draw function, it must send synthetic "draw" calls to all children that don't have their own GdkWindows. This function provides a convenient way of doing this. A container, when it receives a call to its "draw" function, calls gtk_container_propagate_draw() once for each child, passing in the cr the container received. gtk_container_propagate_draw() takes care of translating the origin of cr, and deciding whether the draw needs to be sent to the child. It is a convenient and optimized way of getting the same effect as calling gtk_widget_draw() on the child directly. In most cases, a container can simply either inherit the "draw" implementation from GtkContainer, or do some drawing and then chain to the ::draw implementation from GtkContainer.
Retrieves the focus chain of the container, if one has been set explicitly. If no focus chain has been explicitly set, GTK+ computes the focus chain based on the positions of the children. In that case, GTK+ stores NULL in focusable_widgets and returns FALSE.
Sets a focus chain, overriding the one computed automatically by GTK+. In principle each widget in the chain should be a descendant of the container, but this is not enforced by this method, since it's allowed to set the focus chain before you pack the widgets, or have a widget in the chain that isn't always packed. The necessary checks are done when the focus chain is actually traversed.
Removes a focus chain explicitly set with gtk_container_set_focus_chain().
Finds a child property of a container class by name.
Installs a child property on a container class.
Returns all child properties of a container class.
Modifies a subclass of GtkContainerClass to automatically add and remove the border-width setting on GtkContainer. This allows the subclass to ignore the border width in its size request and allocate methods. The intent is for a subclass to invoke this in its class_init function. gtk_container_class_handle_border_width() is necessary because it would break API too badly to make this behavior the default. So subclasses must "opt in" to the parent class handling border_width for them.
The GtkTable functions allow the programmer to arrange widgets in rows and columns, making it easy to align many widgets next to each other, horizontally and vertically.
Tables are created with a call to gtk_table_new(), the size of which can later be changed with gtk_table_resize().
Widgets can be added to a table using gtk_table_attach() or the more convenient (but slightly less flexible) gtk_table_attach_defaults().
To alter the space next to a specific row, use gtk_table_set_row_spacing(), and for a column, gtk_table_set_col_spacing(). The gaps between all rows or columns can be changed by calling gtk_table_set_row_spacings() or gtk_table_set_col_spacings() respectively. Note that spacing is added between the children, while padding added by gtk_table_attach() is added on either side of the widget it belongs to.
gtk_table_set_homogeneous(), can be used to set whether all cells in the table will resize themselves to the size of the largest widget in the table.
Note
GtkTable has been deprecated. Use GtkGrid instead. It provides the same capabilities as GtkTable for arranging widgets in a rectangular grid, but does support height-for-width geometry management.
