70 | * @Short_description: Base class for widgets which contain other widgets |
71 | * @Title: CtkContainer |
72 | * |
73 | * A CTK+ user interface is constructed by nesting widgets inside widgets. |
74 | * Container widgets are the inner nodes in the resulting tree of widgets: |
75 | * they contain other widgets. So, for example, you might have a #CtkWindow |
76 | * containing a #CtkFrame containing a #CtkLabel. If you wanted an image instead |
77 | * of a textual label inside the frame, you might replace the #CtkLabel widget |
78 | * with a #CtkImage widget. |
79 | * |
80 | * There are two major kinds of container widgets in CTK+. Both are subclasses |
81 | * of the abstract CtkContainer base class. |
82 | * |
83 | * The first type of container widget has a single child widget and derives |
84 | * from #CtkBin. These containers are decorators, which |
85 | * add some kind of functionality to the child. For example, a #CtkButton makes |
86 | * its child into a clickable button; a #CtkFrame draws a frame around its child |
87 | * and a #CtkWindow places its child widget inside a top-level window. |
88 | * |
89 | * The second type of container can have more than one child; its purpose is to |
90 | * manage layout. This means that these containers assign |
91 | * sizes and positions to their children. For example, a #CtkHBox arranges its |
92 | * children in a horizontal row, and a #CtkGrid arranges the widgets it contains |
93 | * in a two-dimensional grid. |
94 | * |
95 | * For implementations of #CtkContainer the virtual method #CtkContainerClass.forall() |
96 | * is always required, since it's used for drawing and other internal operations |
97 | * on the children. |
98 | * If the #CtkContainer implementation expect to have non internal children |
99 | * it's needed to implement both #CtkContainerClass.add() and #CtkContainerClass.remove(). |
100 | * If the CtkContainer implementation has internal children, they should be added |
101 | * with ctk_widget_set_parent() on init() and removed with ctk_widget_unparent() |
102 | * in the #CtkWidgetClass.destroy() implementation. |
103 | * See more about implementing custom widgets at https://wiki.gnome.org/HowDoI/CustomWidgets |
104 | * |
105 | * # Height for width geometry management |
106 | * |
107 | * CTK+ uses a height-for-width (and width-for-height) geometry management system. |
108 | * Height-for-width means that a widget can change how much vertical space it needs, |
109 | * depending on the amount of horizontal space that it is given (and similar for |
110 | * width-for-height). |
111 | * |
112 | * There are some things to keep in mind when implementing container widgets |
113 | * that make use of CTK+’s height for width geometry management system. First, |
114 | * it’s important to note that a container must prioritize one of its |
115 | * dimensions, that is to say that a widget or container can only have a |
116 | * #CtkSizeRequestMode that is %CTK_SIZE_REQUEST_HEIGHT_FOR_WIDTH or |
117 | * %CTK_SIZE_REQUEST_WIDTH_FOR_HEIGHT. However, every widget and container |
118 | * must be able to respond to the APIs for both dimensions, i.e. even if a |
119 | * widget has a request mode that is height-for-width, it is possible that |
120 | * its parent will request its sizes using the width-for-height APIs. |
121 | * |
122 | * To ensure that everything works properly, here are some guidelines to follow |
123 | * when implementing height-for-width (or width-for-height) containers. |
124 | * |
125 | * Each request mode involves 2 virtual methods. Height-for-width apis run |
126 | * through ctk_widget_get_preferred_width() and then through ctk_widget_get_preferred_height_for_width(). |
127 | * When handling requests in the opposite #CtkSizeRequestMode it is important that |
128 | * every widget request at least enough space to display all of its content at all times. |
129 | * |
130 | * When ctk_widget_get_preferred_height() is called on a container that is height-for-width, |
131 | * the container must return the height for its minimum width. This is easily achieved by |
132 | * simply calling the reverse apis implemented for itself as follows: |
133 | * |
134 | * |[<!-- language="C" --> |
135 | * static void |
136 | * foo_container_get_preferred_height (CtkWidget *widget, |
137 | * gint *min_height, |
138 | * gint *nat_height) |
139 | * { |
140 | * if (i_am_in_height_for_width_mode) |
141 | * { |
142 | * gint min_width; |
143 | * |
144 | * CTK_WIDGET_GET_CLASS (widget)->get_preferred_width (widget, |
145 | * &min_width, |
146 | * NULL); |
147 | * CTK_WIDGET_GET_CLASS (widget)->get_preferred_height_for_width |
148 | * (widget, |
149 | * min_width, |
150 | * min_height, |
151 | * nat_height); |
152 | * } |
153 | * else |
154 | * { |
155 | * ... many containers support both request modes, execute the |
156 | * real width-for-height request here by returning the |
157 | * collective heights of all widgets that are stacked |
158 | * vertically (or whatever is appropriate for this container) |
159 | * ... |
160 | * } |
161 | * } |
162 | * ]| |
163 | * |
164 | * Similarly, when ctk_widget_get_preferred_width_for_height() is called for a container or widget |
165 | * that is height-for-width, it then only needs to return the base minimum width like so: |
166 | * |
167 | * |[<!-- language="C" --> |
168 | * static void |
169 | * foo_container_get_preferred_width_for_height (CtkWidget *widget, |
170 | * gint for_height, |
171 | * gint *min_width, |
172 | * gint *nat_width) |
173 | * { |
174 | * if (i_am_in_height_for_width_mode) |
175 | * { |
176 | * CTK_WIDGET_GET_CLASS (widget)->get_preferred_width (widget, |
177 | * min_width, |
178 | * nat_width); |
179 | * } |
180 | * else |
181 | * { |
182 | * ... execute the real width-for-height request here based on |
183 | * the required width of the children collectively if the |
184 | * container were to be allocated the said height ... |
185 | * } |
186 | * } |
187 | * ]| |
188 | * |
189 | * Height for width requests are generally implemented in terms of a virtual allocation |
190 | * of widgets in the input orientation. Assuming an height-for-width request mode, a container |
191 | * would implement the get_preferred_height_for_width() virtual function by first calling |
192 | * ctk_widget_get_preferred_width() for each of its children. |
193 | * |
194 | * For each potential group of children that are lined up horizontally, the values returned by |
195 | * ctk_widget_get_preferred_width() should be collected in an array of #CtkRequestedSize structures. |
196 | * Any child spacing should be removed from the input @for_width and then the collective size should be |
197 | * allocated using the ctk_distribute_natural_allocation() convenience function. |
198 | * |
199 | * The container will then move on to request the preferred height for each child by using |
200 | * ctk_widget_get_preferred_height_for_width() and using the sizes stored in the #CtkRequestedSize array. |
201 | * |
202 | * To allocate a height-for-width container, it’s again important |
203 | * to consider that a container must prioritize one dimension over the other. So if |
204 | * a container is a height-for-width container it must first allocate all widgets horizontally |
205 | * using a #CtkRequestedSize array and ctk_distribute_natural_allocation() and then add any |
206 | * extra space (if and where appropriate) for the widget to expand. |
207 | * |
208 | * After adding all the expand space, the container assumes it was allocated sufficient |
209 | * height to fit all of its content. At this time, the container must use the total horizontal sizes |
210 | * of each widget to request the height-for-width of each of its children and store the requests in a |
211 | * #CtkRequestedSize array for any widgets that stack vertically (for tabular containers this can |
212 | * be generalized into the heights and widths of rows and columns). |
213 | * The vertical space must then again be distributed using ctk_distribute_natural_allocation() |
214 | * while this time considering the allocated height of the widget minus any vertical spacing |
215 | * that the container adds. Then vertical expand space should be added where appropriate and available |
216 | * and the container should go on to actually allocating the child widgets. |
217 | * |
218 | * See [CtkWidget’s geometry management section][geometry-management] |
219 | * to learn more about implementing height-for-width geometry management for widgets. |
220 | * |
221 | * # Child properties |
222 | * |
223 | * CtkContainer introduces child properties. |
224 | * These are object properties that are not specific |
225 | * to either the container or the contained widget, but rather to their relation. |
226 | * Typical examples of child properties are the position or pack-type of a widget |
227 | * which is contained in a #CtkBox. |
228 | * |
229 | * Use ctk_container_class_install_child_property() to install child properties |
230 | * for a container class and ctk_container_class_find_child_property() or |
231 | * ctk_container_class_list_child_properties() to get information about existing |
232 | * child properties. |
233 | * |
234 | * To set the value of a child property, use ctk_container_child_set_property(), |
235 | * ctk_container_child_set() or ctk_container_child_set_valist(). |
236 | * To obtain the value of a child property, use |
237 | * ctk_container_child_get_property(), ctk_container_child_get() or |
238 | * ctk_container_child_get_valist(). To emit notification about child property |
239 | * changes, use ctk_widget_child_notify(). |
240 | * |
241 | * # CtkContainer as CtkBuildable |
242 | * |
243 | * The CtkContainer implementation of the CtkBuildable interface supports |
244 | * a <packing> element for children, which can contain multiple <property> |
245 | * elements that specify child properties for the child. |
246 | * |
247 | * Since 2.16, child properties can also be marked as translatable using |
248 | * the same “translatable”, “comments” and “context” attributes that are used |
249 | * for regular properties. |
250 | * |
251 | * Since 3.16, containers can have a <focus-chain> element containing multiple |
252 | * <widget> elements, one for each child that should be added to the focus |
253 | * chain. The ”name” attribute gives the id of the widget. |
254 | * |
255 | * An example of these properties in UI definitions: |
256 | * |[ |
257 | * <object class="CtkBox"> |
258 | * <child> |
259 | * <object class="CtkEntry" id="entry1"/> |
260 | * <packing> |
261 | * <property name="pack-type">start</property> |
262 | * </packing> |
263 | * </child> |
264 | * <child> |
265 | * <object class="CtkEntry" id="entry2"/> |
266 | * </child> |
267 | * <focus-chain> |
268 | * <widget name="entry1"/> |
269 | * <widget name="entry2"/> |
270 | * </focus-chain> |
271 | * </object> |
272 | * ]| |

3769 | * in container’s draw function, consider using cairo_save() and |
3770 | * cairo_restore() before calling this function. |
3771 | * |
3772 | * When a container receives a call to the draw function, it must send |
3773 | * synthetic #CtkWidget::draw calls to all children that don’t have their |
3774 | * own #CdkWindows. This function provides a convenient way of doing this. |
3775 | * A container, when it receives a call to its #CtkWidget::draw function, |
3776 | * calls ctk_container_propagate_draw() once for each child, passing in |
3777 | * the @cr the container received. |
3778 | * |
3779 | * ctk_container_propagate_draw() takes care of translating the origin of @cr, |
3780 | * and deciding whether the draw needs to be sent to the child. It is a |
3781 | * convenient and optimized way of getting the same effect as calling |
3782 | * ctk_widget_draw() on the child directly. |
3783 | * |
3784 | * In most cases, a container can simply either inherit the |
3785 | * #CtkWidget::draw implementation from #CtkContainer, or do some drawing |
