◆ MessageType

Message types.

Definition at line 138 of file KDbMessageHandler.h.

◆ Option

Constructor & Destructor Documentation

◆ KDbMessageHandler()

KDbMessageHandler::KDbMessageHandler ( QWidget parent = nullptr)

Constructs message handler, parent is a widget that will be a parent for displaying gui elements (e.g. message boxes). Can be 0 for non-gui usage.

Member Function Documentation

◆ askQuestion()

KDbMessageHandler::ButtonCode KDbMessageHandler::askQuestion ( KDbMessageHandler::QuestionType  messageType,
const QString message,
const QString caption = QString(),
KDbMessageHandler::ButtonCode  defaultResult = KDbMessageHandler::Yes,
const KDbGuiItem buttonYes = KDbGuiItem(),
const KDbGuiItem buttonNo = KDbGuiItem(),
const QString dontShowAskAgainName = QString(),
KDbMessageHandler::Options  options = nullptr,
KDbMessageHandler msgHandler = nullptr 

Interactively asks a question. For GUI version, message boxes are used. defaultResult is returned in case when no message handler is installed. message should contain translated string. Value of ButtonCode is returned. Reimplement this. This implementation does nothing, just returns defaultResult.

Definition at line 143 of file KDbMessageHandler.cpp.

◆ messagesEnabled()

bool KDbMessageHandler::messagesEnabled ( ) const
true if the handler is enables so messages are not blocked.

Definition at line 133 of file KDbMessageHandler.cpp.

◆ parentWidget()

QWidget * KDbMessageHandler::parentWidget ( )
a widget that will be parent for displaying gui elements (e.g. message boxes). Can be 0 for non-gui cases.

Definition at line 177 of file KDbMessageHandler.cpp.

◆ redirection()

KDbMessageHandler * KDbMessageHandler::redirection ( )
message redirection for this handler or 0 if there is no redirection.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Definition at line 162 of file KDbMessageHandler.cpp.

◆ setMessagesEnabled()

void KDbMessageHandler::setMessagesEnabled ( bool  enable)

Enables or disabled the handler to block/unblock its messages. Sometimes both lower- and higher-level messages are received, what is not optimal as only one of them should be displayed (e.g. a higher level with details). This can be solved by calling setEnabled(false) shortly before an action that can send the unwanted message. Afterwards messages can be enabled again by calling setEnabled(true). By default messages are enabled.

Definition at line 138 of file KDbMessageHandler.cpp.

◆ setRedirection()

void KDbMessageHandler::setRedirection ( KDbMessageHandler otherHandler)

Sets redirection of all messages for this handler to otherHandler. Passing 0 removes redirection. Setting new redirection replaces previous.

Definition at line 172 of file KDbMessageHandler.cpp.

◆ showErrorMessage() [1/2]

virtual void KDbMessageHandler::showErrorMessage ( const KDbResult result,
KDbMessageHandler::MessageType  messageType = Error,
const QString message = QString(),
const QString caption = QString() 
pure virtual

Shows error message with message text. Existing error message from obj object is also copied, if present.

◆ showErrorMessage() [2/2]

virtual void KDbMessageHandler::showErrorMessage ( KDbMessageHandler::MessageType  messageType,
const QString message,
const QString details = QString(),
const QString caption = QString() 
pure virtual

Shows error message with title (it is not caption) and details.
