## Detailed Description

Class for manipulating the application startup notification.

This class can be used to send information about started application, change the information and receive this information. For detailed description, see kdelibs/kdecore/README.kstartupinfo.

You usually don't need to use this class for sending the notification information, as KDE libraries should do this when an application is started (e.g. KRun class).

For receiving the startup notification info, create an instance and connect to its slots. It will automatically detect started applications and when they are ready.

## Member Enumeration Documentation

enum KStartupInfo::startup_t

- NoMatch - the window doesn't match any existing startup notification
- Match - the window matches an existing startup notification
- CantDetect - unable to detect if the window matches any existing startup notification

Definition at line 261 of file kstartupinfo.h.

## Constructor & Destructor Documentation

KStartupInfo::KStartupInfo | ( | int | flags,
|  | QObject * | parent = `NULL`,
|  | const char * | name = `NULL`
| ) |

Creates an instance that will receive the startup notifications.

The various flags passed may be

- CleanOnCantDetect - when a new unknown window appears, all startup notifications for applications that are not compliant with the startup protocol are removed
- DisableKWinModule - KWinModule, which is normally used to detect new windows, is disabled. With this flag, checkStartup() must be called in order to check newly mapped windows.
- AnnounceSilenceChanges - normally, startup notifications are "removed" when they're silenced, and "recreated" when they're resumed. With this flag, the change is normally announced with gotStartupChange().

Parameters:

  | flags | OR-ed combination of flags
  | parent | the parent of this QObject (can be 0 for no parent)
  | name | the name of the QObject (can be 0 for no name)

Definition at line 114 of file kstartupinfo.cpp.

KStartupInfo::KStartupInfo | ( | bool | clean_on_cantdetect,
|  | QObject * | parent = `0`,
|  | const char * | name = `0`
| ) |

Creates an instance that will receive the startup notifications.

Parameters:

  | clean_on_cantdetect | if true, and a new unknown window appears, removes all notification for applications that are not compliant with the app startup protocol
  | parent | the parent of this QObject (can be 0 for no parent)
  | name | the name of the QObject (can be 0 for no name)

Deprecated:

## Member Function Documentation

void KStartupInfo::disableAutoAppStartedSending | ( | bool | disable = `true` | ) | `[static]`

By default, the startup notification is ended for the application after it shows its first toplevel window.

If you app e.g. has several toplevel windows after its startup, you can disable the automatic handling, and call appStarted() manually after all toplevel windows have been shown.

Since:
  3.2

Definition at line 523 of file kstartupinfo.cpp.

void KStartupInfo::appStarted | ( |  | ) | `[static]`

| Manual notification that the application has started. If you do not map a (toplevel) window, then startup notification will not disappear for the application until a timeout. You can use this as an alternative method in this case. Definition at line 494 of file kstartupinfo.cpp. References currentStartupIdEnv().

void KStartupInfo::appStarted | ( | const QCString & | startup_id | ) | `[static]`

Sends explicit notification that the startup notification with id startup_id should end.

Since:
  3.2

Definition at line 502 of file kstartupinfo.cpp.

References sendFinish(), and sendFinishX().

void KStartupInfo::setNewStartupId | ( | QWidget * | window,
|  | const QCString & | startup_id
| ) | `[static]`

Use this function if the application got a request with startup notification from outside (for example, when KUniqueApplication::newInstance() is called, or e.g.

when khelpcenter opens new URL in its window). The window can be either an already existing and visible window, or a new one, before being shown. Note that this function is usually needed only when a window is reused.

Since:
  3.2

Definition at line 545 of file kstartupinfo.cpp.

References NETRootInfo::isSupported(), and setWindowStartupId().

Referenced by KUniqueApplication::newInstance().

void KStartupInfo::silenceStartup | ( | bool | silence | ) | `[static]`

If your application shows temporarily some window during its startup, for example a dialog, and only after closing it shows the main window, startup notification would normally be shown while the dialog is visible.

To temporarily suspend and resume the notification, use this function. Note that this is cumulative, i.e. after suspending twice, you have to resume twice.

Since:
  3.2

Definition at line 528 of file kstartupinfo.cpp.

QCString KStartupInfo::createNewStartupId | ( |  | ) | `[static]`

Creates and returns new startup id.

The id includes properly setup user timestamp.

  3.3

bool KStartupInfo::sendStartup | ( | const KStartupInfoId & | id,
|  | const KStartupInfoData & | data
| ) | `[static]`

Sends given notification data about started application with the given startup identification.

If no notification for this identification exists yet, it is created, otherwise it's updated. Note that the name field in data is required.

Parameters:

  | id | the id of the application
  | data | the application's data

Returns:
  true if successful, false otherwise

bool KStartupInfo::sendStartupX | ( | Display * | dpy,
|  | const KStartupInfoId & | id,
|  | const KStartupInfoData & | data
| ) | `[static]`

Like sendStartup , uses dpy instead of qt_x11display() for sending the info.

Parameters:

  | dpy | the display of the application. Note that the name field in data is required.
  | id | the id of the application
  | data | the application's data

Returns:
  true if successful, false otherwise

bool KStartupInfo::sendChange | ( | const KStartupInfoId & | id,
|  | const KStartupInfoData & | data
| ) | `[static]`

Sends given notification data about started application with the given startup identification.

This is used for updating the notification info, if no notification for this identification exists, it's ignored.

Parameters:

  | id | the id of the application
  | data | the application's data

Returns:
  true if successful, false otherwise
