/**
|
|
* @short %KDE top level main window
|
|
*
|
|
* Top level widget that provides toolbars, a status line and a frame.
|
|
*
|
|
* It should be used as a top level (parent-less) widget.
|
|
* It manages the geometry for all its children, including your
|
|
* main widget.
|
|
*
|
|
* Normally, you will inherit from TDEMainWindow,
|
|
* then construct (or use some existing) widget as
|
|
* your main view. You can set only one main view.
|
|
*
|
|
* You can add as many toolbars as you like. There can be only one menubar
|
|
* and only one statusbar.
|
|
*
|
|
* The toolbars, menubar, and statusbar can be created by the
|
|
* TDEMainWindow and - unlike the old TDEMainWindow - may, but do not
|
|
* have to, be deleted by you. TDEMainWindow will handle that internally.
|
|
*
|
|
* Height and width can be operated independently from each other. Simply
|
|
* define the minimum/maximum height/width of your main widget and
|
|
* TDEMainWindow will take this into account. For fixed size windows set
|
|
* your main widget to a fixed size.
|
|
*
|
|
* Fixed aspect ratios (heightForWidth()) and fixed width widgets are
|
|
* not supported.
|
|
*
|
|
* TDEMainWindow will set icon, mini icon and caption, which it gets
|
|
* from TDEApplication. It provides full session management, and
|
|
* will save its position, geometry and positions of toolbars and
|
|
* menubar on logout. If you want to save additional data, reimplement
|
|
* saveProperties() and (to read them again on next login)
|
|
* readProperties(). To save special data about your data, reimplement
|
|
* saveGlobalProperties(). To warn user that application or
|
|
* windows have unsaved data on close or logout, reimplement
|
|
* queryClose() and/or queryExit().
|
|
*
|
|
* There are also kRestoreMainWindows convenience functions which
|
|
* can restore all your windows on next login.
|
|
*
|
|
* Note that a TDEMainWindow per-default is created with the
|
|
* WDestructiveClose flag, i.e. it is automatically destroyed when the
|
|
* window is closed. If you do not want this behavior, specify 0 as
|
|
* widget flag in the constructor.

* secondary window.
|
|
*
|
|
* @param name The object name. For session management and window management to work
|
|
* properly, all main windows in the application should have a
|
|
* different name. When passing 0 (the default), TDEMainWindow will create
|
|
* a unique name, but it's recommended to explicitly pass a window name that will
|
|
* also describe the type of the window. If there can be several windows of the same
|
|
* type, append '#' (hash) to the name, and TDEMainWindow will append numbers to make
|
|
* the names unique. For example, for a mail client which has one main window showing
|
|
* the mails and folders, and which can also have one or more windows for composing
|
|
* mails, the name for the folders window should be e.g. "mainwindow" and

|
* automatically destroyed when its window is closed. Pass 0 if

|
|
* If the session did not contain so high a number, the configuration

|
|

* }

|
|
*
|
|
* With this you can easily restore all toplevel windows of your
|
|
* application.
|
|
*
|
|
* If your application uses different kinds of toplevel
|
|
* windows, then you can use TDEMainWindow::classNameOfToplevel(n)
|
|
* to determine the exact type before calling the childMW
|
|
* constructor in the example from above.
|
|
*
|
|
* If your client has only one kind of toplevel widgets (which
|
|
* should be pretty usual) then you should use the RESTORE-macro
|
|
* for backwards compatibility with 3.1 and 3.0 branches:
|
|
*
|
|
* \code
|
|
* if (kapp->isRestored())
|
|
* RESTORE(childMW)
|
|
* else {
|
|
* // create default application as usual
|
|
* }
|
|
* \endcode
|
|
*
|
|
* The macro expands to the term above but is easier to use and
|
|
* less code to write.
|
|
*
|
|
* For new code or if you have more than one kind of toplevel
|
|
* widget (each derived from TDEMainWindow, of course), you can
|
|
* use the templated kRestoreMainWindows global functions:
|
|
*
|
|
* \code
|
|
* if (kapp->isRestored())
|
|
* kRestoreMainWindows< childMW1, childMW2, childMW3 >();
|
|
* else {
|
|
* // create default application as usual
|
|
* }
|
|
* \endcode
|
|
*
|
|
* Currently, these functions are provided for up to three
|
|
* template arguments. If you need more, tell us. To help you in
|
|
* deciding whether or not you can use kRestoreMainWindows, a
|
|
* define KDE_RESTORE_MAIN_WINDOWS_NUM_TEMPLATE_ARGS is provided.

function other than indicating severe errors. Better ask the

user on queryClose() (see below).
|
|
|
|
A typical usage of queryExit() is to write configuration data back.
|
|
Note that the application may continue to run after queryExit()
|
|
(the user may have canceled a shutdown), so you should not do any cleanups
|
|
here. The purpose of queryExit() is purely to prepare the application
|

(with possible user interaction) so it can safely be closed later (without
|
|
user interaction).
|

If you need to do serious things on exit (like shutting a
|
|
dial-up connection down), connect to the signal
|
|
TDEApplication::shutDown().
|
|
|
|
Default implementation returns @p true. Returning @p false will

cancel the exiting. In the latter case, the last window will

|
|
|
The purpose of this function is to prepare the window in a way that it is
|
|
safe to close it, i.e. without the user losing some data.
|
|
|
|
Default implementation returns true. Returning @p false will cancel
|
|
the closing, and, if TDEApplication::sessionSaving() is true, it will also
|

cancel KDE logout.

Reimplement this function to prevent the user from losing data.

Example:
|

\code

switch ( KMessageBox::warningYesNoCancel( this,

case KMessageBox::Yes :

case KMessageBox::No :

return true;
|

default: // cancel
|
|
return false;

|
\endcode
|
|
|
|
Note that you should probably @em not actually close the document from
|
|
within this method, as it may be called by the session manager before the
|
|
session is saved. If the document is closed before the session save occurs,
|
|
its location might not be properly saved. In addition, the session shutdown

may be canceled, in which case the document should remain open.
