Formulärlayouter
Kirigami.FormLayout components make it easy for you to create forms that conform to the KDE Human Interface Guidelines. They are optimal for settings dialogs and for large groups of controls and input fields that are related to each other.
När tillräckligt utrymme tillhandahålls, upptar formulärlayouter två kolumner. Kolumnen till vänster upptas av beteckningarna tillhandahållna för formulärets underliggande komponenter, medan den högra upptas av själva de underliggande komponenterna själva. I mer utrymmesbegränsade fönster (eller på en mobil), består formulär av en enda vertikal kolumn med de underliggande komponenternas beteckningar placerade ovanför deras respektive komponent.
Enkelt formulär
Kirigami.FormLayout components are similar in use to QtQuick Layout components such as ColumnLayout or RowLayout. The child components will be automatically arranged according to the size available to the form layout.
Children of a Kirigami.FormLayout have a property named Kirigami.FormData.label. This property lets you set the label that will be provided for the child component in question.
import QtQuick
import QtQuick.Layouts
import QtQuick.Controls as Controls
import org.kde.kirigami as Kirigami
Kirigami.ApplicationWindow {
pageStack.initialPage: Kirigami.Page {
Kirigami.FormLayout {
anchors.fill: parent
Controls.TextField {
Kirigami.FormData.label: "TextField 1:"
}
Controls.TextField {
Kirigami.FormData.label: "TextField 2:"
}
Controls.TextField {
Kirigami.FormData.label: "TextField 3:"
}
}
}
}

Sektioner och avskiljare
FormLayouts can also be divided into sections. Setting where a section starts is as easy as setting a child component's Kirigami.FormData.isSection to true. This will provide the component with some extra margin at the top to demarcate the start of the new section.
Kirigami.Separator components are best suited for starting new sections. Separators are used to draw a thin horizontal line, demarcating the end of a section. If you would rather not have a line drawn between sections, you can use a standard QML Item property. Alternatively you could use the Kirigami.FormData.isSection property on any other component.
However, this is not recommended. On components where Kirigami.FormData.isSection is set to true
, the label text provided for this component's Kirigami.FormData.label property will be displayed as the section's header text.
Varning
This does not apply to every component, hence the recommendation that you use Kirigami.Separator or Item components in places where you would like to use a header text.Sidhuvudtexten är större än normal beteckningstext och tillhandahåller användare med en snygg visuell ledtråd om vad formulärets layoutsektion handlar om.
Kirigami.FormLayout {
anchors.fill: parent
Controls.TextField {
Kirigami.FormData.label: "TextField 1:"
}
Controls.TextField {
Kirigami.FormData.label: "TextField 2:"
}
Controls.TextField {
Kirigami.FormData.label: "TextField 3:"
}
Kirigami.Separator {
Kirigami.FormData.isSection: true
Kirigami.FormData.label: "New Section!"
}
ColumnLayout {
Kirigami.FormData.label: "Radio buttons"
Controls.RadioButton {
text: "Radio 1"
checked: true
}
Controls.RadioButton {
text: "Radio 2"
}
Controls.RadioButton {
text: "Radio 3"
}
}
Item {
Kirigami.FormData.isSection: true
Kirigami.FormData.label: "Another Section! (lineless though)"
}
Controls.TextField {
Kirigami.FormData.label: "TextField 4:"
}
Controls.TextField {
Kirigami.FormData.label: "TextField 5:"
}
Controls.TextField {
Kirigami.FormData.label: "TextField 5:"
}
}

Markeringsbara underliggande objekt
A handy feature of Kirigami.FormLayout is that you can add checkboxes to its children. This can be useful in settings pages where you might want to let the user enable or disable a setting, and also want the user to provide some extra information in a component such as a textfield.
Kirigami.FormLayout {
anchors.fill: parent
Controls.TextField {
Kirigami.FormData.label: "First name:"
}
Controls.TextField {
Kirigami.FormData.label: "Middle name:"
Kirigami.FormData.checkable: true
enabled: Kirigami.FormData.checked
}
Controls.TextField {
Kirigami.FormData.label: "Last name:"
}
}

Tvinga skrivbords- eller mobillayout
If you would rather have your form layout stay consistent regardless of your application's environment, you can use the wideMode property of the Kirigami.FormLayout component:
- När den är inställd till
true
, struktureras formulärlayouten för en skrivbordsoptimerad bred (med dubbla kolumner) skärmlayout. - När den är inställd till
false
, struktureras formulärlayouten som en mobillayout (enstaka kolumn)
Kirigami.FormLayout {
anchors.fill: parent
wideMode: false
Controls.TextField {
Kirigami.FormData.label: "TextField 1:"
}
Controls.TextField {
Kirigami.FormData.label: "TextField 2:"
}
Controls.TextField {
Kirigami.FormData.label: "TextField 3:"
}
}

Justera beteckningar
There are instances when you want a label to be assigned to components that have more than one line or to a list of components. This can be achieved by putting the Kirigami.FormData.label in the ColumnLayout, as you might have noticed in Sections and Separators. By default the label is positioned in the vertical center of the layout, which is not always desirable. We can change this with help of Kirigami.FormData.labelAlignment.
Kirigami.FormLayout {
anchors.fill: parent
ColumnLayout {
Kirigami.FormData.label: "This is a label:"
Kirigami.FormData.labelAlignment: Qt.AlignTop
Controls.Label {
text: "This is some rather long text \nthat should elide to multiple lines \nto show how the label gets aligned."
elide: Text.elideLeft
}
}
}

En formulärlayout med beteckning justerad längst upp
Att ställa in beteckningens justering är särskilt bekvämt för att hantera komponenter eller listor över komponenter vars storlek du inte känner till i förväg. Elisa är ett mycket bra exempel på det:

Kommentarbeteckningen är bara justerad längst upp när motsvarande komponent har mer än en rad
Vi kan göra någonting liknande med en Javascript ternär operator:
Kirigami.FormLayout {
anchors.fill: parent
ColumnLayout {
Kirigami.FormData.label: "This is a label:"
Kirigami.FormData.labelAlignment: labelText.text.lineCount > 1 ? Qt.AlignTop : Qt.AlignVCenter
Controls.Label {
id: labelText
text: "This is some rather long text \nthat should elide to a new line \nso it appears below the Form Label."
elide: Text.elideLeft
}
}
}
