## Detailed Description

A dialog base class with standard buttons and predefined layouts.

Provides basic functionality needed by nearly all dialogs.

It offers the standard action buttons you'd expect to find in a dialog as well as the capability to define at most three configurable buttons. You can define a main widget that contains your specific dialog layout

The class takes care of the geometry management. You only need to define a minimum size for the widget you want to use as the main widget.

By default, the dialog is non-modal.

Standard buttons (action buttons):\n

You select which buttons should be displayed, but you do not choose the order in which they are displayed. This ensures a standard interface in KDE. The button order can be changed, but this ability is only available for a central KDE control tool. The following buttons are available: OK, Cancel/Close, Apply/Try, Default, Help and three user definable buttons: User1, User2 and User3. You must specify the text of the UserN buttons. Each button emit a signal, so you can choose to connect that signal.

The default action of the Help button will open the help system if you have provided a path to the help text. The default action of Ok and Cancel will run QDialog.accept() and QDialog.reject(), which you can override by reimplementing slotButtonClicked(). The default action of the Close button will close the dialog.

Note that the KDialog will animate a button press when the user presses Escape. The button that is enabled is either Cancel, Close or the button that is defined by setEscapeButton(). Your custom dialog code should reimplement the keyPressEvent and animate the cancel button so that the dialog behaves like regular dialogs.

Layout:\n

The dialog consists of a help area on top (becomes visible if you define a help path and use enableLinkedHelp()), the main area which is the built-in dialog face or your own widget in the middle and by default a button box at the bottom. The button box can also be placed at the right edge (to the right of the main widget). Use setButtonsOrientation() to control this behavior. A separator can be placed above the button box (or to the left when the button box is at the right edge).

Standard compliance:\n

The marginHint() and spacingHint() sizes shall be used whenever you lay out the interior of a dialog. One special note. If you make your own action buttons (OK, Cancel etc), the space between the buttons shall be spacingHint(), whereas the space above, below, to the right and to the left shall be marginHint(). If you add a separator line above the buttons, there shall be a marginHint() between the buttons and the separator and a marginHint() above the separator as well.

Example:\n

       KDialog *dialog = new KDialog( this );
       dialog->setCaption( "My title" );
       dialog->setButtons( KDialog.Ok | KDialog.Cancel | KDialog.Apply );

       FooWidget *widget = new FooWidget( dialog );
       dialog->setMainWidget( widget );
       connect( dialog, SIGNAL( applyClicked() ), widget, SLOT( save() ) );
       connect( dialog, SIGNAL( okClicked() ), widget, SLOT( save() ) );
       connect( widget, SIGNAL( changed( bool ) ), dialog, SLOT( enableButtonApply( bool ) ) );

       dialog->enableButtonApply( false );
       dialog->show();

"KDE Dialog example"

This class can be used in many ways. Note that most KDE ui widgets and many of KDE core applications use the KDialog so for more inspiration you should study the code for these.

setCaption | ( | self, |
|  | QString | caption,
|  | bool | modified
| ) |  |  |

Makes a KDE compliant caption.

Sets the status of the Details button.

setEscapeButton | ( | self, |
|  | KDialog.ButtonCode | id
| ) |  |  |

Sets the button that will be activated when the Escape key is pressed.

     }

Parameters:

  | button | is the type KDialog.ButtonCode

updateGeometry | ( |  | self ) |

Updates the margins and spacings.

Deprecated:

## Static Method Documentation

bool avoidArea | ( | QWidget | widget,
|  | QRect | area,
|  | int | screen=-1
| ) |  |  |

Places widget so that it doesn't cover a certain area of the screen. This is typically used by the "find dialog" so that the match it finds can be read. For screen, see centerOnScreen

Returns:
  true on success (widget doesn't cover area anymore, or never did), false on failure (not enough space found)

centerOnScreen | ( | QWidget | widget,
|  | int | screen=-1
| ) |  |  |

Centers widget on the desktop, taking multi-head setups into account. If screen is -1, widget will be centered on its current screen (if it was shown already) or on the primary screen. If screen is -3, widget will be centered on the screen that currently contains the mouse pointer. screen will be ignored if a merged display (like Xinerama) is not in use, or merged display placement is not enabled in kdeglobals.

int groupSpacingHint | ( |  | ) |

Returns the number of pixels that should be used to visually separate groups of related options in a dialog according to the KDE standard.

Since:
  4.2

QString makeStandardCaption | ( | QString | userCaption,
|  | QWidget | window=0,
|  | KDialog.CaptionFlags | flags=KDialog.HIGCompliantCaption
| ) |  |  |

Builds a caption that contains the application name along with the userCaption using a standard layout.

To make a compliant caption for your window, simply do: setWindowTitle(KDialog.makeStandardCaption(yourCaption));

To ensure that the caption is appropriate to the desktop in which the application is running, pass in a pointer to the window the caption will be applied to.

If using a KDialog or KMainWindow subclass, call setCaption instead and an appropraite standard caption will be created for you

Parameters:

  | userCaption | The caption string you want to display in the window caption area. Do not include the application name!
  | window | a pointer to the window this application will apply to
  | flags |

Returns:
  the created caption

int marginHint | ( |  | ) |

Returns the number of pixels that should be used between a dialog edge and the outermost widget(s) according to the KDE standard.

Deprecated:
  Use the style's pixelMetric() function to query individual margins. Different platforms may use different values for the four margins.

resizeLayout | ( | QWidget | widget,
|  | int | margin,
|  | int | spacing
| ) |  |  |

Resize every layout associated with lay and its children.

Parameters:

  | lay | layout to be resized
  | margin | The new layout margin
  | spacing | The new layout spacing

Deprecated:
  Use QLayout functions where necessary. Setting margin and spacing values recursively for all children prevents QLayout from creating platform native layouts.

resizeLayout | ( | QLayout | lay,
|  | int | margin,
|  | int | spacing
| ) |  |  |

Resize every layout associated with lay and its children.

Parameters:

  | lay | layout to be resized
  | margin | The new layout margin
  | spacing | The new layout spacing

Deprecated:
  Use QLayout functions where necessary. Setting margin and spacing values recursively for all children prevents QLayout from creating platform native layouts.

setAllowEmbeddingInGraphicsView | ( | bool | allowEmbedding
| ) |  |  |

Allow embedding the dialogs based on KDialog into a graphics view. By default embedding is not allowed, dialogs will appear as separate windows.

Since:
  4.6

int spacingHint | ( |  | ) |

Returns the number of pixels that should be used between widgets inside a dialog according to the KDE standard.

Deprecated:
  Use the style's layoutSpacing() function to query individual spacings. Different platforms may use different values depending on widget types and pairs.
