Window is the base class for all widgets in FOX.
All widgets are organized in a tree structure, with a single root window at the top. Each window links to its parent window, next and previous siblings windows, as well as its first and last child windows. A window also has an owner window, which is the window responsible for its creation and destruction. In most cases, the owner window will be the same as the parent window, except for top-level windows. The focus window determines to which child keyboard messages are delegated if the window is a composite window (i.e. if it has children). Windows are geometrically arranged by their immediate parent window; the actual method of placement is determined by the type of layout supported by the parent window, as well as the window's layout hints. The position of a window is determined relative to its immediate parent window; A window can send a message to its target object when an event happens.
Window classes.
| void FX::FXWindow::dropFinished | ( | FXDragAction | action = DRAG_REJECT | ) | const |
Sent by the drop target in response to SEL_DND_DROP.
The drag action should be the same as the action the drop target reported to the drag source in reponse to the SEL_DND_MOTION message. This function notifies the drag source that its part of the drop transaction is finished, and that it is free to release any resources involved in the drag operation. Calling dropFinished() is advisable in cases where the drop target needs to perform complex processing on the data received from the drag source, prior to returning from the SEL_DND_DROP message handler.
|
virtual |
Move the window immediately, in the parent's coordinate system.
Update the server representation as well if the window is realized. Perform layout of the children when necessary.
Reimplemented in FX::FXTopWindow, FX::FXMDIChild, and FX::FXRootWindow.
|
virtual |
Move and resize the window immediately, in the parent's coordinate system.
Update the server representation as well if the window is realized. Perform layout of the children when necessary.
Reimplemented in FX::FXIconList, FX::FXTopWindow, FX::FXMDIChild, and FX::FXRootWindow.
|
virtual |
Resize the window to the specified width and height immediately, updating the server representation as well, if the window was realized.
Perform layout of the children when necessary.
Reimplemented from FX::FXDrawable.
Reimplemented in FX::FXIconList, FX::FXTopWindow, FX::FXMDIChild, and FX::FXRootWindow.
|
virtual |
This changes the default window which responds to the Return key in a dialog.
If the flag is true, this window becomes the default window; when the flag is false, this window will be no longer the default window. Finally, when the flag is maybe, the default window will revert to the initial default window.
Reimplemented in FX::FXButton.
| void FX::FXWindow::setHeight | ( | FXint | h | ) |
Set the window height; and flag the widget as being in need of layout by its parent.
This does not immediately update the server- side representation of the widget.
| void FX::FXWindow::setWidth | ( | FXint | w | ) |
Set the window width; and flag the widget as being in need of layout by its parent.
This does not immediately update the server- side representation of the widget.
|
virtual |
Translate message for localization; using the current FXTranslator, an attempt is made to translate the given message into the current language.
An optional hint may be passed to break any ties in case more than one tranlation is possible for the given message text. In addition, the name of the widget is passed as context name so that translations for a single dialog may be grouped together.
