164 \class QDialog -

165 \brief The QDialog class is the base class of dialog windows. -

166 -

167 \ingroup dialog-classes -

168 \ingroup abstractwidgets -

169 \inmodule QtWidgets -

170 -

171 A dialog window is a top-level window mostly used for short-term -

172 tasks and brief communications with the user. QDialogs may be -

173 modal or modeless. QDialogs can -

174 provide a \l{#return}{return value}, and they can have \l{#default}{default buttons}. QDialogs can also have a QSizeGrip in their -

175 lower-right corner, using setSizeGripEnabled(). -

176 -

177 Note that QDialog (and any other widget that has type \c Qt::Dialog) uses -

178 the parent widget slightly differently from other classes in Qt. A dialog is -

179 always a top-level widget, but if it has a parent, its default location is -

180 centered on top of the parent's top-level widget (if it is not top-level -

181 itself). It will also share the parent's taskbar entry. -

182 -

183 Use the overload of the QWidget::setParent() function to change -

184 the ownership of a QDialog widget. This function allows you to -

185 explicitly set the window flags of the reparented widget; using -

186 the overloaded function will clear the window flags specifying the -

187 window-system properties for the widget (in particular it will -

188 reset the Qt::Dialog flag). -

189 -

190 \section1 Modal Dialogs -

191 -

192 A \b{modal} dialog is a dialog that blocks input to other -

193 visible windows in the same application. Dialogs that are used to -

194 request a file name from the user or that are used to set -

195 application preferences are usually modal. Dialogs can be -

196 \l{Qt::ApplicationModal}{application modal} (the default) or -

197 \l{Qt::WindowModal}{window modal}. -

198 -

199 When an application modal dialog is opened, the user must finish -

200 interacting with the dialog and close it before they can access -

201 any other window in the application. Window modal dialogs only -

202 block access to the window associated with the dialog, allowing -

203 the user to continue to use other windows in an application. -

204 -

205 The most common way to display a modal dialog is to call its -

206 exec() function. When the user closes the dialog, exec() will -

207 provide a useful \l{#return}{return value}. Typically, -

208 to get the dialog to close and return the appropriate value, we -

209 connect a default button, e.g. \uicontrol OK, to the accept() slot and a -

210 \uicontrol Cancel button to the reject() slot. -

211 Alternatively you can call the done() slot with \c Accepted or -

212 \c Rejected. -

213 -

214 An alternative is to call setModal(true) or setWindowModality(), -

215 then show(). Unlike exec(), show() returns control to the caller -

216 immediately. Calling setModal(true) is especially useful for -

217 progress dialogs, where the user must have the ability to interact -

218 with the dialog, e.g. to cancel a long running operation. If you -

219 use show() and setModal(true) together to perform a long operation, -

220 you must call QApplication::processEvents() periodically during -

221 processing to enable the user to interact with the dialog. (See -

222 QProgressDialog.) -

223 -

224 \section1 Modeless Dialogs -

225 -

226 A \b{modeless} dialog is a dialog that operates -

227 independently of other windows in the same application. Find and -

228 replace dialogs in word-processors are often modeless to allow the -

229 user to interact with both the application's main window and with -

230 the dialog. -

231 -

232 Modeless dialogs are displayed using show(), which returns control -

233 to the caller immediately. -

234 -

235 If you invoke the \l{QWidget::show()}{show()} function after hiding -

236 a dialog, the dialog will be displayed in its original position. This is -

237 because the window manager decides the position for windows that -

238 have not been explicitly placed by the programmer. To preserve the -

239 position of a dialog that has been moved by the user, save its position -

240 in your \l{QWidget::closeEvent()}{closeEvent()} handler and then -

241 move the dialog to that position, before showing it again. -

242 -

243 \target default -

244 \section1 Default Button -

245 -

246 A dialog's \e default button is the button that's pressed when the -

247 user presses Enter (Return). This button is used to signify that -

248 the user accepts the dialog's settings and wants to close the -

249 dialog. Use QPushButton::setDefault(), QPushButton::isDefault() -

250 and QPushButton::autoDefault() to set and control the dialog's -

251 default button. -

252 -

253 \target escapekey -

254 \section1 Escape Key -

255 -

256 If the user presses the Esc key in a dialog, QDialog::reject() -

257 will be called. This will cause the window to close: The \l{QCloseEvent}{close event} cannot be \l{QEvent::ignore()}{ignored}. -

258 -

259 \section1 Extensibility -

260 -

261 Extensibility is the ability to show the dialog in two ways: a -

262 partial dialog that shows the most commonly used options, and a -

263 full dialog that shows all the options. Typically an extensible -

264 dialog will initially appear as a partial dialog, but with a -

265 \uicontrol More toggle button. If the user presses the \uicontrol More button down, -

266 the dialog is expanded. The \l{Extension Example} shows how to achieve -

267 extensible dialogs using Qt. -

268 -

269 \target return -

270 \section1 Return Value (Modal Dialogs) -

271 -

272 Modal dialogs are often used in situations where a return value is -

273 required, e.g. to indicate whether the user pressed \uicontrol OK or -

274 \uicontrol Cancel. A dialog can be closed by calling the accept() or the -

275 reject() slots, and exec() will return \c Accepted or \c Rejected -

276 as appropriate. The exec() call returns the result of the dialog. -

277 The result is also available from result() if the dialog has not -

278 been destroyed. -

279 -

280 In order to modify your dialog's close behavior, you can reimplement -

281 the functions accept(), reject() or done(). The -

282 \l{QWidget::closeEvent()}{closeEvent()} function should only be -

283 reimplemented to preserve the dialog's position or to override the -

284 standard close or reject behavior. -
