Detailed Description

This item simply adds an external padding to contentItem's size.

Padding item behaves similarly to QtQuick.Controls/Controlpadding, but is more lightweight and thus efficient. Its implicit size is set to that of its contentItem's implicit size plus padding.

import QtQuick.Controls as QQC2
import org.kde.kirigami as Kirigami
 
Kirigami.Padding {
    padding: Kirigami.Units.largeSpacing
    contentItem: QQC2.Button {}
}

With this component it is possible to add external paddings as a placeholder for an item, whereas with QtQuick.Layouts you would need to manually assign or bind attached properties whenever content item changes.

import QtQuick
import QtQuick.Layouts
import QtQuick.Controls as QQC2
import org.kde.kirigami as Kirigami
 
ColumnLayout {
    property alias contentItem: container.contentItem
 
    Kirigami.Heading {
        Layout.fillWidth: true
        Layout.margins: Kirigami.Units.largeSpacing
    }
 
    Kirigami.Padding {
        id: container
        Layout.fillWidth: true
        padding: Kirigami.Units.largeSpacing
    }
}

Property Documentation

availableHeight

qreal Padding::availableHeight

read

The height available to the contentItem after deducting vertical padding from the width of the Padding.

Definition at line 136 of file padding.h.

availableWidth

qreal Padding::availableWidth

read

The width available to the contentItem after deducting horizontal padding from the width of the Padding.

Definition at line 131 of file padding.h.

bottomPadding

qreal Padding::bottomPadding

readwrite

This property holds the padding on the bottom side.

Unless explicitly set, it falls back to verticalPadding and then to padding.

Definition at line 126 of file padding.h.

contentItem

QQuickItem * Padding::contentItem

readwrite

This property holds the visual content Item.

It will automatically resized taking into account all the paddings

Definition at line 70 of file padding.h.

horizontalPadding

qreal Padding::horizontalPadding

readwrite

This property holds the horizontal padding.

Unless explicitly set, the value is equal to padding.

Definition at line 89 of file padding.h.

implicitContentHeight

qreal Padding::implicitContentHeight

read

The implicitHeight of its contentItem, or 0 if not present.

Definition at line 146 of file padding.h.

implicitContentWidth

qreal Padding::implicitContentWidth

read

The implicitWidth of its contentItem, or 0 if not present.

Definition at line 141 of file padding.h.

leftPadding

qreal Padding::leftPadding

readwrite

This property holds the padding on the left side.

Unless explicitly set, it falls back to horizontalPadding and then to padding. This always refers to the actual left, it won't be flipped on RTL layouts.

Definition at line 104 of file padding.h.

padding

qreal Padding::padding

readwrite

This property holds the default padding.

Padding adds a space between each edge of this ITem and its contentItem, effectively controlling its size. To specify a padding value for a specific edge of the control, set its relevant property:

• leftPadding
• rightPadding
• topPadding
• bottomPadding

Definition at line 82 of file padding.h.

rightPadding

qreal Padding::rightPadding

readwrite

This property holds the padding on the right side.

Unless explicitly set, it falls back to horizontalPadding and then to padding. This always refers to the actual right, it won't be flipped on RTL layouts.

Definition at line 119 of file padding.h.

topPadding

qreal Padding::topPadding

readwrite

the padding on the top side.

Unless explicitly set, it falls back to verticalPadding and then to padding.

Definition at line 111 of file padding.h.

verticalPadding

qreal Padding::verticalPadding

readwrite

This property holds the vertical padding.

Unless explicitly set, the value is equal to padding.

Definition at line 96 of file padding.h.
