The QMessageBox class provides a modal dialog with a short message, an icon, and some buttons.
|
||
|
|
|
||
|
|
|
||
|
|
<p> Message boxes are used to provide informative messages and to ask
|
||
|
|
simple questions.
|
||
|
|
<p> QMessageBox provides a range of different messages, arranged
|
||
|
|
roughly along two axes: severity and complexity.
|
||
|
|
<p> Severity is

|
||
|
|
<td valign="top">For message boxes that ask a question as part of normal
|
||
|

operation. Some style guides recommend using Information for this
|
||
|
|
purpose.

<td valign="top">For message boxes that tell the user about critical errors.
|
||
|
|
</table></center>
|
||
|
|
<p> The message box has a different icon for each of the severity levels.
|
||
|
|
<p> Complexity is one button (OK) for simple messages, or two or even
|
||
|
|
three buttons for questions.
|
||
|
|
<p> There are static functions for the most common cases.
|
||
|
|
<p> Examples:
|
||
|
|
<p> If a program is unable to find a supporting file, but can do perfectly
|
||
|
|
well without it:
|
||
|
|
<p> <pre>
|
||
|
|
QMessageBox::<a href="#information">information</a>( this, "Application name",
|
||
|
|
"Unable to find the user preferences file.\n"
|
||
|
|
"The factory default will be used instead." );
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
<p> <a href="#question">question</a>() is useful for simple yes/no questions:
|
||
|
|
<p> <pre>
|
||
|
|
if ( QFile::<a href="qfile.html#exists">exists</a>( filename ) &&
|
||
|
|
QMessageBox::<a href="#question">question</a>(
|
||
|
|
this,
|
||
|
|
<a href="qobject.html#tr">tr</a>("Overwrite File? -- Application Name"),
|
||
|
|
<a href="qobject.html#tr">tr</a>("A file called %1 already exists."
|
||
|
|
"Do you want to overwrite it?")
|
||
|
|
.arg( filename ),
|
||
|
|
<a href="qobject.html#tr">tr</a>("&Yes"), tr("&No"),
|
||
|
|
<a href="qstring.html#QString-null">QString::null</a>, 0, 1 ) )
|
||
|
|
return false;
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
<p> <a href="#warning">warning</a>() can be used to tell the user about unusual errors, or
|
||
|
|
errors which can't be easily fixed:
|
||
|
|
<p> <pre>
|
||
|
|
switch( QMessageBox::<a href="#warning">warning</a>( this, "Application name",
|
||
|
|
"Could not connect to the <mumble> server.\n"
|
||
|
|
"This program can't function correctly "
|
||
|
|
"without the server.\n\n",
|
||
|
|
"Retry",
|
||
|
|
"Quit", 0, 0, 1 ) ) {
|
||
|
|
case 0: // The user clicked the Retry again button or pressed Enter
|
||
|
|
// try again
|
||
|
|
break;
|
||
|
|
case 1: // The user clicked the Quit or pressed Escape
|
||
|
|
// exit
|
||
|
|
break;
|
||
|
|
}
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
<p> The text part of all message box messages can be either rich text
|
||
|
|
or plain text. If you specify a rich text formatted string, it
|
||
|
|
will be rendered using the default stylesheet. See
|
||
|
|
<a href="qstylesheet.html#defaultSheet">QStyleSheet::defaultSheet</a>() for details. With certain strings that
|
||
|
|
contain XML meta characters, the auto-rich text detection may
|
||
|
|
fail, interpreting plain text incorrectly as rich text. In these
|
||
|
|
rare cases, use <a href="qstylesheet.html#convertFromPlainText">QStyleSheet::convertFromPlainText</a>() to convert
|
||
|
|
your plain text string to a visually equivalent rich text string
|
||
|
|
or set the text format explicitly with <a href="#setTextFormat">setTextFormat</a>().
|
||
|
|
<p> Note that the Microsoft Windows User Interface Guidelines
|
||
|
|
recommend using the application name as the window's caption.
|
||
|
|
<p> Below are more examples of how to use the static member functions.
|
||
|
|
After these examples you will find an overview of the non-static
|
||
|
|
member functions.
|
||
|
|
<p> Exiting a program is part of its normal operation. If there is
|
||
|
|
unsaved data the user probably should be asked if they want to
|
||
|
|
save the data. For example:
|
||
|
|
<p> <pre>
|
||
|
|
switch( QMessageBox::<a href="#information">information</a>( this, "Application name here",
|
||
|
|
"The document contains unsaved changes\n"
|
||
|
|
"Do you want to save the changes before exiting?",
|
||
|
|
"&Save", "&Discard", "Cancel",
|
||
|
|
0, // Enter == button 0
|
||
|
|
2 ) ) { // Escape == button 2
|
||
|
|
case 0: // Save clicked or Alt+S pressed or Enter pressed.
|
||
|
|
// save
|
||
|
|
break;
|
||
|
|
case 1: // Discard clicked or Alt+D pressed
|
||
|
|
// don't save but exit
|
||
|
|
break;
|
||
|
|
case 2: // Cancel clicked or Escape pressed
|
||
|
|
// don't exit
|
||
|
|
break;
|
||
|
|
}
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
<p> The Escape button cancels the entire exit operation, and pressing
|
||
|
|
Enter causes the changes to be saved before the exit occurs.
|
||
|
|
<p> Disk full errors are unusual and they certainly can be hard to
|
||
|
|
correct. This example uses predefined buttons instead of
|
||
|
|
hard-coded button texts:
|
||
|
|
<p> <pre>
|
||
|
|
switch( QMessageBox::<a href="#warning">warning</a>( this, "Application name here",
|
||
|
|
"Could not save the user preferences,\n"
|
||
|
|
"because the disk is full. You can delete\n"
|
||
|
|
"some files and press Retry, or you can\n"
|
||
|
|
"abort the Save Preferences operation.",
|
||
|
|
QMessageBox::Retry | QMessageBox::Default,
|
||
|
|
QMessageBox::Abort | QMessageBox::Escape )) {
|
||
|
|
case QMessageBox::Retry: // Retry clicked or Enter pressed
|
||
|
|
// try again
|
||
|
|
break;
|
||
|
|
case QMessageBox::Abort: // Abort clicked or Escape pressed
|
||
|
|
// abort
|
||
|
|
break;
|
||
|
|
}
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
<p> The <a href="#critical">critical</a>() function should be reserved for critical errors. In
|
||
|
|
this example errorDetails is a <a href="qstring.html">QString</a> or const char*, and QString
|
||
|
|
is used to concatenate several strings:
|
||
|
|
<p> <pre>
|
||
|
|
QMessageBox::<a href="#critical">critical</a>( 0, "Application name here",
|
||
|
|
QString("An internal error occurred. Please ") +
|
||
|
|
"call technical support at 1234-56789 and report\n"+
|
||
|
|
"these numbers:\n\n" + errorDetails +
|
||
|
|
"\n\nApplication will now exit." );
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
<p> In this example an OK button is displayed.
|
||
|
|
<p> QMessageBox provides a very simple About box which displays an
|
||
|
|
appropriate icon and the string you provide:
|
||
|
|
<p> <pre>
|
||
|
|
QMessageBox::<a href="#about">about</a>( this, "About <Application>",
|
||
|
|
"<Application> is a <one-paragraph blurb>\n\n"
|
||
|
|
"Copyright 1991-2003 Such-and-such. "
|
||
|
|
"<License words here.>\n\n"
|
||
|
|
"For technical support, call 1234-56789 or see\n"
|
||
|
|
"http://www.such-and-such.com/Application/\n" );
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
<p> See <a href="#about">about</a>() for more information.
|
||
|
|
<p> If you want your users to know that the application is built using
|
||
|
|
Qt (so they know that you use high quality tools) you might like
|
||
|
|
to add an "About Qt" menu option under the Help menu to invoke
|
||
|
|
<a href="#aboutQt">aboutQt</a>().
|
||
|
|
<p> If none of the standard message boxes is suitable, you can create a
|
||
|
|
QMessageBox from scratch and use custom button texts:
|
||
|
|
<p> <pre>
|
||
|
|
QMessageBox mb( "Application name here",
|
||
|
|
"Saving the file will overwrite the original file on the disk.\n"
|
||
|
|
"Do you really want to save?",
|
||
|
|
QMessageBox::<a href="#Icon-enum">Information</a>,
|
||
|
|
QMessageBox::Yes | QMessageBox::Default,
|
||
|
|
QMessageBox::No,
|
||
|
|
QMessageBox::Cancel | QMessageBox::Escape );
|
||
|
|
mb.<a href="#setButtonText">setButtonText</a>( QMessageBox::Yes, "Save" );
|
||
|
|
mb.<a href="#setButtonText">setButtonText</a>( QMessageBox::No, "Discard" );
|
||
|
|
switch( mb.<a href="qdialog.html#exec">exec</a>() ) {
|
||
|
|
case QMessageBox::Yes:
|
||
|
|
// save and exit
|
||
|
|
break;
|
||
|
|
case QMessageBox::No:
|
||
|
|
// exit without saving
|
||
|
|
break;
|
||
|
|
case QMessageBox::Cancel:
|
||
|
|
// don't save and don't exit
|
||
|
|
break;
|
||
|
|
}
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
<p> QMessageBox defines two enum types: Icon and an unnamed button type.
|
||
|
|
Icon defines the <a href="#Icon-enum">Question</a>, <a href="#Icon-enum">Information</a>, <a href="#Icon-enum">Warning</a>, and <a href="#Icon-enum">Critical</a> icons for each GUI style. It is used by the constructor
|
||
|
|
and by the static member functions <a href="#question">question</a>(), <a href="#information">information</a>(),
|
||
|
|
<a href="#warning">warning</a>() and <a href="#critical">critical</a>(). A function called <a href="#standardIcon">standardIcon</a>() gives
|
||
|
|
you access to the various icons.
|
||
|
|
<p> The button types are:
|
||
|
|
<ul>
|
||
|
|
<li> Ok - the default for single-button message boxes
|
||
|
|
<li> Cancel - note that this is <em>not</em> automatically Escape
|
||
|
|
<li> Yes
|
||
|
|
<li> No
|
||
|
|
<li> Abort
|
||
|
|
<li> Retry
|
||
|
|
<li> Ignore
|
||
|
|
<li> YesAll
|
||
|
|
<li> NoAll
|
||
|
|
</ul>
|
||
|
|
<p> Button types can be combined with two modifiers by using OR, '|':
|
||
|
|
<ul>
|
||
|

<p> The <a href="#text">text</a>(), <a href="#icon">icon</a>() and <a href="#iconPixmap">iconPixmap</a>() functions provide access to the

current text and pixmap of the message box. The <a href="#setText">setText</a>(), <a href="#setIcon">setIcon</a>()
|
||
|
|
and <a href="#setIconPixmap">setIconPixmap</a>() let you change it. The difference between
|
||
|
|
setIcon() and setIconPixmap() is that the former accepts a
|
||
|
|
QMessageBox::Icon and can be used to set standard icons, whereas the
|
||
|
|
latter accepts a <a href="qpixmap.html">QPixmap</a> and can be used to set custom icons.
|
||
|
|
<p> <a href="#setButtonText">setButtonText</a>() and <a href="#buttonText">buttonText</a>() provide access to the buttons.
|
||
|
|
<p> QMessageBox has no signals or slots.
