| 61 | * SECTION:windows |
| 62 | * @Short_description: Onscreen display areas in the target window system |
| 63 | * @Title: Windows |
| 64 | * |
| 65 | * A #CdkWindow is a (usually) rectangular region on the screen. |
| 66 | * It’s a low-level object, used to implement high-level objects such as |
| 67 | * #CtkWidget and #CtkWindow on the CTK+ level. A #CtkWindow is a toplevel |
| 68 | * window, the thing a user might think of as a “window” with a titlebar |
| 69 | * and so on; a #CtkWindow may contain many #CdkWindows. For example, |
| 70 | * each #CtkButton has a #CdkWindow associated with it. |
| 71 | * |
| 72 | * # Composited Windows # {#COMPOSITED-WINDOWS} |
| 73 | * |
| 74 | * Normally, the windowing system takes care of rendering the contents |
| 75 | * of a child window onto its parent window. This mechanism can be |
| 76 | * intercepted by calling cdk_window_set_composited() on the child |
| 77 | * window. For a “composited” window it is the |
| 78 | * responsibility of the application to render the window contents at |
| 79 | * the right spot. |
| 80 | * |
| 81 | * # Offscreen Windows # {#OFFSCREEN-WINDOWS} |
| 82 | * |
| 83 | * Offscreen windows are more general than composited windows, since |
| 84 | * they allow not only to modify the rendering of the child window onto |
| 85 | * its parent, but also to apply coordinate transformations. |
| 86 | * |
| 87 | * To integrate an offscreen window into a window hierarchy, one has |
| 88 | * to call cdk_offscreen_window_set_embedder() and handle a number of |
| 89 | * signals. The #CdkWindow::pick-embedded-child signal on the embedder |
| 90 | * window is used to select an offscreen child at given coordinates, |
| 91 | * and the #CdkWindow::to-embedder and #CdkWindow::from-embedder signals |
| 92 | * on the offscreen window are used to translate coordinates between |
| 93 | * the embedder and the offscreen window. |
| 94 | * |
| 95 | * For rendering an offscreen window onto its embedder, the contents |
| 96 | * of the offscreen window are available as a surface, via |
| 97 | * cdk_offscreen_window_get_surface(). |
| 98 | */ |

| 101 | /* Historically a CdkWindow always matches a platform native window, |
| 102 | * be it a toplevel window or a child window. In this setup the |
| 103 | * CdkWindow (and other CdkDrawables) were platform independent classes, |
| 104 | * and the actual platform specific implementation was in a delegate |
| 105 | * object available as “impl” in the window object. |
| 106 | * |
| 107 | * With the addition of client side windows and offscreen windows this |
| 108 | * changes a bit. The application-visible CdkWindow object behaves as |
| 109 | * it did before, but not all such windows now have a corresponding native |
| 110 | * window. Instead windows that are “client side” are emulated by the cdk |
| 111 | * code such that clipping, drawing, moving, events etc work as expected. |
| 112 | * |
| 113 | * For CdkWindows that have a native window the “impl” object is the |
| 114 | * same as before. However, for all client side windows the impl object |
| 115 | * is shared with its parent (i.e. all client windows descendants of one |
| 116 | * native window has the same impl. |
| 117 | * |
| 118 | * Additionally there is a new type of platform independent impl object, |
| 119 | * CdkOffscreenWindow. All windows of type CDK_WINDOW_OFFSCREEN get an impl |
| 120 | * of this type (while their children are generally CDK_WINDOW_CHILD virtual |
| 121 | * windows). Such windows work by allocating a #cairo_surface_t as the backing |
| 122 | * store for drawing operations, which is resized with the window. |
| 123 | * |
| 124 | * CdkWindows have a pointer to the “impl window” they are in, i.e. |
| 125 | * the topmost CdkWindow which have the same “impl” value. This is stored |
| 126 | * in impl_window, which is different from the window itself only for client |
| 127 | * side windows. |
| 128 | * All CdkWindows (native or not) track the position of the window in the parent |
| 129 | * (x, y), the size of the window (width, height), the position of the window |
| 130 | * with respect to the impl window (abs_x, abs_y). We also track the clip |
| 131 | * region of the window wrt parent windows, in window-relative coordinates (clip_region). |
| 132 | * |
| 133 | * All toplevel windows are native windows, but also child windows can be |
| 134 | * native (although not children of offscreens). We always listen to |
| 135 | * a basic set of events (see get_native_event_mask) for these windows |
| 136 | * so that we can emulate events for any client side children. |
| 137 | * |
| 138 | * For native windows we apply the calculated clip region as a window shape |
| 139 | * so that eg. client side siblings that overlap the native child properly |
| 140 | * draws over the native child window. |

| 3170 | * cdk_window_begin_paint_region() and cdk_window_end_paint() around |
| 3171 | * emissions of the expose_event signal. That is, if you’re writing an |
| 3172 | * expose event handler, you can assume that the exposed area in |
| 3173 | * #CdkEventExpose has already been cleared to the window background, |
| 3174 | * is already set as the clip region, and already has a backing store. |
| 3175 | * Therefore in most cases, application code need not call |
| 3176 | * cdk_window_begin_paint_region(). (You can disable the automatic |
| 3177 | * calls around expose events on a widget-by-widget basis by calling |
| 3178 | * ctk_widget_set_double_buffered().) |
| 3179 | * |
| 3180 | * If you call this function multiple times before calling the |
| 3181 | * matching cdk_window_end_paint(), the backing stores are pushed onto |
| 3182 | * a stack. cdk_window_end_paint() copies the topmost backing store |

| 3205 | * Indicates that you are beginning the process of redrawing @region |
| 3206 | * on @window, and provides you with a #CdkDrawingContext. |
| 3207 | * |
| 3208 | * If @window is a top level #CdkWindow, backed by a native window |
| 3209 | * implementation, a backing store (offscreen buffer) large enough to |
| 3210 | * contain @region will be created. The backing store will be initialized |
| 3211 | * with the background color or background surface for @window. Then, all |
| 3212 | * drawing operations performed on @window will be diverted to the |
| 3213 | * backing store. When you call cdk_window_end_frame(), the contents of |
| 3214 | * the backing store will be copied to @window, making it visible |
| 3215 | * on screen. Only the part of @window contained in @region will be |
| 3216 | * modified; that is, drawing operations are clipped to @region. |
| 3217 | * |
| 3218 | * The net result of all this is to remove flicker, because the user |
| 3219 | * sees the finished product appear all at once when you call |
| 3220 | * cdk_window_end_draw_frame(). If you draw to @window directly without |
| 3221 | * calling cdk_window_begin_draw_frame(), the user may see flicker |
| 3222 | * as individual drawing operations are performed in sequence. |
| 3223 | * |
| 3224 | * When using CTK+, the widget system automatically places calls to |
| 3225 | * cdk_window_begin_draw_frame() and cdk_window_end_draw_frame() around |
| 3226 | * emissions of the `CtkWidget::draw` signal. That is, if you’re |
| 3227 | * drawing the contents of the widget yourself, you can assume that the |
| 3228 | * widget has a cleared background, is already set as the clip region, |
| 3229 | * and already has a backing store. Therefore in most cases, application |
| 3230 | * code in CTK does not need to call cdk_window_begin_draw_frame() |
| 3231 | * explicitly. |
| 3232 | * |
| 3233 | * Returns: (transfer none): a #CdkDrawingContext context that should be |

| 3608 | * |
| 3609 | * Note that calling cairo_reset_clip() on the resulting #cairo_t will |
| 3610 | * produce undefined results, so avoid it at all costs. |
| 3611 | * |
| 3612 | * Typically, this function is used to draw on a #CdkWindow out of the paint |
| 3613 | * cycle of the toolkit; this should be avoided, as it breaks various assumptions |
| 3614 | * and optimizations. |
| 3615 | * |
| 3616 | * If you are drawing on a native #CdkWindow in response to a %CDK_EXPOSE event |
| 3617 | * you should use cdk_window_begin_draw_frame() and cdk_drawing_context_get_cairo_context() |
| 3618 | * instead. CTK will automatically do this for you when drawing a widget. |
| 3619 | * |
| 3620 | * Returns: A newly created Cairo context. Free with |
| 3621 | * cairo_destroy() when you are done drawing. |

| 4809 | * With update debugging enabled, calls to |
| 4810 | * cdk_window_invalidate_region() clear the invalidated region of the |
| 4811 | * screen to a noticeable color, and CDK pauses for a short time |
| 4812 | * before sending exposes to windows during |
| 4813 | * cdk_window_process_updates(). The net effect is that you can see |
| 4814 | * the invalid region for each window and watch redraws as they |
| 4815 | * occur. This allows you to diagnose inefficiencies in your application. |
| 4816 | * |
| 4817 | * In essence, because the CDK rendering model prevents all flicker, |
| 4818 | * if you are redrawing the same region 400 times you may never |
| 4819 | * notice, aside from noticing a speed problem. Enabling update |
| 4820 | * debugging causes CTK to flicker slowly and noticeably, so you can |
| 4821 | * see exactly what’s being redrawn when, in what order. |
| 4822 | * |
| 4823 | * The --ctk-debug=updates command line option passed to CTK+ programs |
| 4824 | * enables this debug option at application startup time. That's |
| 4825 | * usually more useful than calling cdk_window_set_debug_updates() |
| 4826 | * yourself, though you might want to use this function to enable |
| 4827 | * updates sometime after application startup time. |

| 8585 | * cdk_pointer_grab: |

| 8587 | * @owner_events: if %FALSE then all pointer events are reported with respect to |
| 8588 | * @window and are only reported if selected by @event_mask. If %TRUE then pointer |
| 8589 | * events for this application are reported as normal, but pointer events outside |
| 8590 | * this application are reported with respect to @window and only if selected by |
| 8591 | * @event_mask. In either mode, unreported events are discarded. |
| 8592 | * @event_mask: specifies the event mask, which is used in accordance with |
| 8593 | * @owner_events. Note that only pointer events (i.e. button and motion events) |
| 8594 | * may be selected. |
| 8595 | * @confine_to: (allow-none): If non-%NULL, the pointer will be confined to this |
| 8596 | * window during the grab. If the pointer is outside @confine_to, it will |
| 8597 | * automatically be moved to the closest edge of @confine_to and enter |
| 8598 | * and leave events will be generated as necessary. |
| 8599 | * @cursor: (allow-none): the cursor to display while the grab is active. If this is %NULL then |
| 8600 | * the normal cursors are used for @window and its descendants, and the cursor |
| 8601 | * for @window is used for all other windows. |
| 8602 | * @time_: the timestamp of the event which led to this pointer grab. This usually |
| 8603 | * comes from a #CdkEventButton struct, though %CDK_CURRENT_TIME can be used if |
| 8604 | * the time isn’t known. |
| 8605 | * |
| 8606 | * Grabs the pointer (usually a mouse) so that all events are passed to this |
| 8607 | * application until the pointer is ungrabbed with cdk_pointer_ungrab(), or |
| 8608 | * the grab window becomes unviewable. |
| 8609 | * This overrides any previous pointer grab by this client. |
| 8610 | * |
| 8611 | * Pointer grabs are used for operations which need complete control over mouse |
| 8612 | * events, even if the mouse leaves the application. |
| 8613 | * For example in CTK+ it is used for Drag and Drop, for dragging the handle in |
| 8614 | * the #CtkHPaned and #CtkVPaned widgets. |
| 8615 | * |
| 8616 | * Note that if the event mask of an X window has selected both button press and |
| 8617 | * button release events, then a button press event will cause an automatic |
| 8618 | * pointer grab until the button is released. |
| 8619 | * X does this automatically since most applications expect to receive button |
| 8620 | * press and release events in pairs. |
| 8621 | * It is equivalent to a pointer grab on the window with @owner_events set to |
| 8622 | * %TRUE. |
| 8623 | * |
| 8624 | * If you set up anything at the time you take the grab that needs to be cleaned |
| 8625 | * up when the grab ends, you should handle the #CdkEventGrabBroken events that |
| 8626 | * are emitted when the grab ends unvoluntarily. |

| 11576 | * @length: the length of the data to retrieve in bytes. Data is |
| 11577 | * considered to be retrieved in 4 byte chunks, so @length |
| 11578 | * will be rounded up to the next highest 4 byte boundary |
| 11579 | * (so be careful not to pass a value that might overflow |
| 11580 | * when rounded up). |
| 11581 | * @pdelete: if %TRUE, delete the property after retrieving the |
| 11582 | * data. |
| 11583 | * @actual_property_type: (out) (transfer none): location to store the |
| 11584 | * actual type of the property. |
| 11585 | * @actual_format: (out): location to store the actual return format of the |
| 11586 | * data; either 8, 16 or 32 bits. |
| 11587 | * @actual_length: location to store the length of the retrieved data, in |
| 11588 | * bytes. Data returned in the 32 bit format is stored |
| 11589 | * in a long variable, so the actual number of 32 bit |
| 11590 | * elements should be be calculated via |
| 11591 | * @actual_length / sizeof(glong) to ensure portability to |
| 11592 | * 64 bit systems. |
| 11593 | * @data: (out) (array length=actual_length) (transfer full): location |
| 11594 | * to store a pointer to the data. The retrieved data should be |
| 11595 | * freed with g_free() when you are finished using it. |
| 11596 | * |
| 11597 | * Retrieves a portion of the contents of a property. If the |
| 11598 | * property does not exist, then the function returns %FALSE, |
| 11599 | * and %CDK_NONE will be stored in @actual_property_type. |
| 11600 | * |
| 11601 | * The XGetWindowProperty() function that cdk_property_get() |
| 11602 | * uses has a very confusing and complicated set of semantics. |
| 11603 | * Unfortunately, cdk_property_get() makes the situation |
| 11604 | * worse instead of better (the semantics should be considered |
| 11605 | * undefined), and also prints warnings to stderr in cases where it |
| 11606 | * should return a useful error to the program. You are advised to use |
| 11607 | * XGetWindowProperty() directly until a replacement function for |
| 11608 | * cdk_property_get() is provided. |
| 11609 | * |
| 11610 | * Returns: %TRUE if data was successfully received and stored |
| 11611 | * in @data, otherwise %FALSE. |
