◆ request_close()
|
virtual |
This is called by the GraphicsEngine to request that the window (or whatever) close itself or, in general, make itself invalid, at the next call to process_events().
By that time we promise the gsg pointer will be cleared.
Reimplemented from GraphicsOutput.
Definition at line 434 of file graphicsWindow.cxx.
References request_properties(), and WindowProperties::set_open.
◆ request_open()
|
virtual |
This is called by the GraphicsEngine to request that the window (or whatever) open itself or, in general, make itself valid, at the next call to process_events().
Reimplemented from GraphicsOutput.
Definition at line 421 of file graphicsWindow.cxx.
References request_properties(), and WindowProperties::set_open.
◆ request_properties()
| void GraphicsWindow::request_properties | ( | const WindowProperties & | requested_properties | ) |
Requests a property change on the window.
For example, use this method to request a window change size or minimize or something.
The change is not made immediately; rather, the request is saved and will be applied the next time the window task is run (probably at the next frame).
Definition at line 147 of file graphicsWindow.cxx.
References WindowProperties::add_properties(), WindowProperties::get_size, and WindowProperties::has_size.
Referenced by request_close(), and request_open().
◆ set_close_now()
|
virtual |
This is called by the GraphicsEngine to insist that the window be closed immediately.
This is only called from the window thread.
Reimplemented from GraphicsOutput.
Definition at line 445 of file graphicsWindow.cxx.
References WindowProperties::set_open, and set_properties_now().
◆ set_properties_now()
|
virtual |
Applies the requested set of properties to the window, if possible, for instance to request a change in size or minimization status.
The window properties are applied immediately, rather than waiting until the next frame. This implies that this method may *only* be called from within the window thread.
The properties that have been applied are cleared from the structure by this function; so on return, whatever remains in the properties structure are those that were unchanged for some reason (probably because the underlying interface does not support changing that property on an open window).

◆ supports_window_procs()
|
virtual |
Returns whether this window supports adding of Windows proc handlers.
Reimplemented in WinGraphicsWindow.
Definition at line 746 of file graphicsWindow.cxx.
◆ verify_window_sizes()
|
virtual |
Determines which of the indicated window sizes are supported by available hardware (e.g.
in fullscreen mode).
On entry, dimen is an array containing contiguous x,y pairs specifying possible display sizes; it is numsizes*2 words long. The function will zero out any invalid x,y size pairs. The return value is the number of valid sizes that were found.
Note this doesn't guarantee a resize attempt will work; you still need to check the return value.
(It might be better to implement some sort of query interface that returns an array of supported sizes, but this way is somewhat simpler and will do the job on most cards, assuming they handle the std sizes the app knows about.)
Reimplemented in wdxGraphicsWindow9.

Member Data Documentation
◆ get_close_request_event
| string GraphicsWindow::get_close_request_event |
Returns the name of the event set via set_close_request_event().
If this string is nonempty, then when the user requests to close window, this event will be generated instead. See set_close_request_event().
Definition at line 74 of file graphicsWindow.h.
◆ get_input_device
| InputDevice * GraphicsWindow::get_input_device |
Returns the nth input device associated with the window.
Typically, a window will have exactly one input device: the keyboard/mouse pair.
Definition at line 87 of file graphicsWindow.h.
Referenced by MouseAndKeyboard::set_source().
◆ get_input_device_name
| string GraphicsWindow::get_input_device_name |
Returns the name of the nth input device.
Definition at line 88 of file graphicsWindow.h.
◆ get_num_input_devices
| int GraphicsWindow::get_num_input_devices |
Returns the number of separate input devices associated with the window.
Typically, a window will have exactly one input device: the keyboard/mouse pair. However, some windows may have no input devices, and others may add additional devices, for instance for a joystick.
Definition at line 87 of file graphicsWindow.h.
◆ get_properties
| const WindowProperties GraphicsWindow::get_properties |
Returns the current properties of the window.
Definition at line 63 of file graphicsWindow.h.
◆ get_rejected_properties
| WindowProperties GraphicsWindow::get_rejected_properties |
Returns the set of properties that have recently been requested, but could not be applied to the window for some reason.
This set of properties will remain unchanged until they are changed by a new failed request, or clear_rejected_properties() is called.
Definition at line 65 of file graphicsWindow.h.
◆ get_requested_properties
| const WindowProperties GraphicsWindow::get_requested_properties |
Returns the properties of the window that are currently requested.
These properties will be applied to the window (if valid) at the next execution of process_events().
Definition at line 64 of file graphicsWindow.h.
◆ get_unexposed_draw
|
inline |
See set_unexposed_draw().
Definition at line 78 of file graphicsWindow.h.
Referenced by wglGraphicsWindow::begin_frame(), and wdxGraphicsWindow9::begin_frame().
◆ get_window_event
| string GraphicsWindow::get_window_event |
Returns the name of the event that is generated when this window is modified externally, e.g.
to be resized or closed by the user. See set_window_event().
Definition at line 70 of file graphicsWindow.h.
◆ get_window_handle
|
inline |
Returns the WindowHandle corresponding to this window on the desktop.
This is mainly useful for communicating with external libraries. Use window_handle->get_os_handle()->get_handle(), or window_handle->get_string_handle(), to get the actual OS-specific window handle object, whatever type that might be.
Definition at line 81 of file graphicsWindow.h.
◆ is_closed
|
inline |
Returns true if the window has not yet been opened, or has been fully closed, false if it is open.
The window is not opened immediately after GraphicsEngine::make_window() is called; nor is it closed immediately after GraphicsEngine::remove_window() is called. Either operation may take a frame or two.
Definition at line 66 of file graphicsWindow.h.
◆ set_close_request_event
| void GraphicsWindow::set_close_request_event |
Sets the event that is triggered when the user requests to close the window, e.g.
via alt-F4, or clicking on the close box.
The default for each window is for this event to be the empty string, which means the window-close request is handled immediately by Panda (and the window will be closed without the app getting a chance to intervene). If you set this to a nonempty string, then the window is not closed, but instead the event is thrown. It is then up to the app to respond appropriately, for instance by presenting an "are you sure?" dialog box, and eventually calling close_window() when the user is sure.
It is considered poor form to set this string and then not handle the event. This can frustrate the user by making it difficult for him to cleanly shut down the application (and may force the user to hard-kill the app, or reboot the machine).
Definition at line 74 of file graphicsWindow.h.
◆ set_unexposed_draw
|
inline |
If this flag is false, the window is redrawn only after it has received a recent "unexpose" or "draw" event from the underlying windowing systme.
If this flag is true, the window is redrawn every frame regardless. Setting this false may prevent the window from redrawing unnecessarily when it is hidden, and may play nicer with other windows on the desktop, but may adversely affect frame rate even when the window is fully visible; setting it true will ensure that the window contents are always current.
Definition at line 78 of file graphicsWindow.h.
◆ set_window_event
| void GraphicsWindow::set_window_event |
Changes the name of the event that is generated when this window is modified externally, e.g.
to be resized or closed by the user.
By default, all windows have the same window event unless they are explicitly changed. When the event is generated, it includes one parameter: the window itself.
