35 | \brief Abstract base type providing functionality common to all controls. |
36 | |
37 | Control is the base type of user interface controls. It receives input |
38 | events from the window system, and paints a representation of itself on |
39 | the screen. |
40 | |
41 | \section1 Control Layout |
42 | |
43 | The following diagram illustrates the layout of a typical control: |
44 | |
45 | \image qtquickcontrols-control.png |
46 | |
47 | The \l {Item::}{implicitWidth} and \l {Item::}{implicitHeight} of a control |
48 | are typically based on the implicit sizes of the background and the content |
49 | item plus any insets and paddings. These properties determine how large |
50 | the control will be when no explicit \l {Item::}{width} or |
51 | \l {Item::}{height} is specified. |
52 | |
53 | The geometry of the \l {Control::}{contentItem} is determined by the padding. |
54 | The following example reserves 10px padding between the boundaries of the |
55 | control and its content: |
56 | |
57 | \code |
58 | Control { |
59 | padding: 10 |
60 | |
61 | contentItem: Text { |
62 | text: "Content" |
63 | } |
64 | } |
65 | \endcode |
66 | |
67 | The \l {Control::}{background} item fills the entire width and height of the |
68 | control, unless insets or an explicit size have been given for it. Background |
69 | insets are useful for extending the touchable/interactive area of a control |
70 | without affecting its visual size. This is often used on touch devices to |
71 | ensure that a control is not too small to be interacted with by the user. |
72 | Insets affect the size of the control, and hence will affect how much space |
73 | they take up in a layout, for example. |
74 | |
75 | Negative insets can be used to make the background larger than the control. |
76 | The following example uses negative insets to place a shadow outside the |
77 | control's boundaries: |
78 | |
79 | \code |
80 | Control { |
81 | topInset: -2 |
82 | leftInset: -2 |
83 | rightInset: -6 |
84 | bottomInset: -6 |
85 | |
86 | background: BorderImage { |
87 | source: ":/images/shadowed-background.png" |
88 | } |
89 | } |
90 | \endcode |
91 | |
92 | \section1 Event Handling |
93 | |
94 | All controls, except non-interactive indicators, do not let clicks and |
95 | touches through to items below them. For example, the \c console.log() |
96 | call in the example below will never be executed when clicking on the |
97 | Pane, because the \l MouseArea is below it in the scene: |
98 | |
99 | \code |
100 | MouseArea { |
101 | anchors.fill: parent |
102 | onClicked: console.log("MouseArea was clicked") |
103 | |
104 | Pane { |
105 | anchors.fill: parent |
106 | } |
107 | } |
108 | \endcode |
109 | |
110 | Wheel events are consumed by controls if \l wheelEnabled is \c true. |

989 | \qmlproperty font QtQuick.Controls::Control::font |
990 | |
991 | This property holds the font currently set for the control. |
992 | |
993 | This property describes the control's requested font. The font is used by the control's |
994 | style when rendering standard components, and is available as a means to ensure that custom |
995 | controls can maintain consistency with the native platform's native look and feel. It's common |
996 | that different platforms, or different styles, define different fonts for an application. |
997 | |
998 | The default font depends on the system environment. ApplicationWindow maintains a system/theme |
999 | font which serves as a default for all controls. There may also be special font defaults for |
1000 | certain types of controls. You can also set the default font for controls by either: |
1001 | |
1002 | \list |
1003 | \li passing a custom font to QGuiApplication::setFont(), before loading the QML; or |
1004 | \li specifying the fonts in the \l {Qt Quick Controls 2 Configuration File}{qtquickcontrols2.conf file}. |
1005 | \endlist |
1006 | |
1007 | Finally, the font is matched against Qt's font database to find the best match. |
1008 | |
1009 | Control propagates explicit font properties from parent to children. If you change a specific |
1010 | property on a control's font, that property propagates to all of the control's children, |
1011 | overriding any system defaults for that property. |

1089 | Padding adds a space between each edge of the content item and the |
1090 | background item, effectively controlling the size of the content item. To |

1100 | |
1101 | \note Different styles may specify the default padding for certain controls |
1102 | in different ways, and these ways may change over time as the design |
1103 | guidelines that the style is based on evolve. To ensure that these changes |
1104 | don't affect the padding values you have specified, it is best to use the |
1105 | most specific properties available. For example, rather than setting |
1106 | the \l padding property: |

1108 | \code |

1110 | \endcode |
