Lådor

Lådor tillhandahåller snabbåtkomst till kontroller och sidor i ditt program.

Lådor är paneler som glider ut från programfönstrets sidor. De kan befolkas med interaktiva element som Kirigami åtgärder, knappar, text, med mera.

Lådor har olika typer, skepnader och former. På den här sidan går vi igenom alla typer och ger en översikt över deras karaktärer.

Global låda

Den globala lådan är en standardfunktion i KDE:s mobilprogram och kan ibland också finnas i deras skrivbordsinkarnationer. Den innehåller programmets huvudmeny: här ingår alla funktioner som inte är specifika för den nuvarande sidan men ändå signifikanta för allmän navigering eller interaktion med programmet.

It can be activated by tapping the hamburger menu or by swiping from the left edge to the middle of the screen in Left to Right mode or from the right edge in Right to Left mode.

Kirigami.GlobalDrawer components are what we use to create such drawers. These are set to the globalDrawer property of the Kirigami.ApplicationWindow that forms the basis of our Kirigami application.

Kirigami.ApplicationWindow {

    globalDrawer: Kirigami.GlobalDrawer {
        actions: [
            Kirigami.Action {
                text: "Kirigami Action 1"
            },
            Kirigami.Action {
                text: "Kirigami Action 2"
            },
            Kirigami.Action {
                text: i18n("Quit")
                icon.name: "gtk-quit"
                shortcut: StandardKey.Quit
                onTriggered: Qt.quit()
            }
        ]
    }
    ...
}

Sidhuvud

Sidhuvud kan användas för att placera orörliga komponenter längst upp i din globala låda. Sidhuvudkomponenter förblir på plats även om din globala låda innehåller nästlade Kirigami-åtgärder som ersätter det nuvarande lagret i den globala lådan.

Din valda sidhuvudkomponent kan anges med den globala lådans egenskap header.

globalDrawer: Kirigami.GlobalDrawer {

    header: Kirigami.AbstractApplicationHeader {

        contentItem: Kirigami.SearchField {
            id: searchField
            Layout.fillWidth: true
        }
    }

    actions: [
        Kirigami.Action {
            text: "Kirigami Action 1"
        },
        Kirigami.Action {
            text: "Kirigami Action 2"
        },
        Kirigami.Action {
            text: i18n("Quit")
            icon.name: "application-exit"
            shortcut: StandardKey.Quit
            onTriggered: Qt.quit()
        }
    ]
}

Our global drawer now shows the search bar component we set as the header

Anpassa till skrivbordet

Medan globala lådor med panelstil kan vara användbara i mobilomgivningar, kan de vara för stora för skrivbordsdatorer.

Thankfully, Kirigami global drawers provide an isMenu property. When set to true, they turn into more traditional menus only on the desktop.

Anmärkning

I menyläget är inte sidhuvuden och baner synliga.

globalDrawer: Kirigami.GlobalDrawer {
    isMenu: true

    actions: [
        Kirigami.Action {
            text: "Kirigami Action 1"
        },
        Kirigami.Action {
            text: "Kirigami Action 2"
        },
        Kirigami.Action {
            text: i18n("Quit")
            icon.name: "application-exit"
            shortcut: StandardKey.Quit
            onTriggered: Qt.quit()
        }
    ]
}

Baner

Baner låter dig visa en titel och en ikon längst upp i din globala låda (till och med ovanför sidhuvudet).

By default, banners are only visible on mobile environments. You can change this by setting the global drawer component's bannerVisible property to true.

Titles, set with the title property, can be used to pretty up your global drawer and make it seem less sparse. More importantly, it can remind your users that this is a global and app-wide drawer rather than a local drawer.

There is also a titleIcon property, which can be paired with your title to make the global drawer even more aesthetically pleasing. This icon will be placed to the left of the title.

globalDrawer: Kirigami.GlobalDrawer {
    title: "My Global Drawer"
    titleIcon: "kde"
    bannerVisible: true
    actions: [
        Kirigami.Action {
            text: "Kirigami Action 1"
        },
        Kirigami.Action {
            text: "Kirigami Action 2"
        },
        Kirigami.Action {
            text: i18n("Quit")
            icon.name: "application-exit"
            shortcut: StandardKey.Quit
            onTriggered: Qt.quit()
        }
    ]
}

The titleIcon property takes names for system-wide icons according to the FreeDesktop specification. These icons and icon names can be viewed with KDE's CuttleFish application which comes with plasma-sdk, or by visiting FreeDesktop's icon naming specification.

Context Drawers

While a Kirigami.GlobalDrawer displays global actions available throughout your application, a Kirigami.ContextDrawer should be used to display actions that are only relevant in certain contexts. This is usually used in separate pages.

A context drawer will only show up if any contextualActions have been created as part of the Page.actions group . It also behaves differently depending on whether it is being used on a mobile platform or on a desktop.

On a desktop, when a window has enough space, contextual actions show up as part of the actions group in the top toolbar. When space is limited, such as on a mobile device or in a narrow window, contextual actions are hidden behind a hamburger menu on the right side. This is different from other actions in the actions group, namely actions.main, actions.left and actions.right; these do not get hidden in space-constrained windows, and are instead collapsed into their respective icons.

Context drawer with contextual actions hidden

Context drawer showing all contextual actions

On mobile, the drawer always consists of actions hidden behind a hamburger menu. It can be activated by tapping the hamburger menu or by swiping from the right edge to the middle of the screen in Left to Right mode or from the left edge in Right to Left mode. If you are on a desktop and want to test the mobile interface, you can run your application with the environment variable QT_QUICK_CONTROLS_MOBILE=1.

Same example above, running in mobile mode

Modala lådor och lådor på plats

Kirigami erbjuder två ytterligare sorters lådor, modala lådor och lådor på plats. De är mycket lika varandra: båda fyller hela programmets bredd eller höjd och kan placeras vid programfönstrets kanter. Dock reagerar de olika på användarinteraktion.

Modal drawers darken the rest of the application and, like overlay sheets , will be dismissed when clicking on a darkened area.
Lådor på plats låter användaren fortsätta interagera med resten av programmet utan att de avfärdas, och gör inte andra områden mörkare.

These two drawers are so similar because they can, in fact, be implemented using the same Kirigami component: Kirigami.OverlayDrawer . Here are a few important inherited properties of this component to keep in mind:

Popup.modal controls whether the drawer will be modal or inline depending on a boolean value
Drawer.edge controls which edge of the application window the drawer will appear on; options for this property are part of the Edge enum , namely Qt.TopEdge, Qt.RightEdge, Qt.BottomEdge, and Qt.LeftEdge
Popup.contentItem contains the component that will form the content of your drawer

import QtQuick.Controls 2.15 as Controls

Kirigami.Page {

    Kirigami.OverlayDrawer {
        id: bottomDrawer
        edge: Qt.BottomEdge
        // Ställ in modal till false för att göra lådan på plats.
        modal: true

        contentItem: RowLayout {
            Layout.fillWidth: true

            Controls.Label {
                Layout.fillWidth: true
                text: "Say hello to my little drawer!"
            }
            Controls.Button {
                text: "Close"
                onClicked: bottomDrawer.close()
            }
        }
    }

    Controls.Button {
        text: "Open bottomDrawer"
        onClicked: bottomDrawer.open()
    }
}

Inline drawer on the bottom edge of the screen

A use case for bottom overlay drawers: NeoChat

NeoChat uses bottom overlay drawers to provide the user with a number of actions they can perform on a message they have long pressed. Here is a simplified example of what that looks like:

Kirigami.Page {

    ListView {
        model: App.MessageModel
        delegate: MessageDelegate {
            onPressAndHold: bottomDrawer.open()
        }
    }

   Kirigami.OverlayDrawer {
       id: bottomDrawer
       height: popupContent.implicitHeight
       edge: Qt.BottomEdge
       padding: 0
       leftPadding: 0
       rightPadding: 0
       bottomPadding: 0
       topPadding: 0

       parent: applicationWindow().overlay

       ColumnLayout {
           id: popupContent
           width: parent.width
           spacing: 0
           
           // Meddelandeinformation
           ...
           
           // Meddelandeåtgärder
           Kirigami.BasicListItem {
               text: "Reply"
               onClicked: {
                   bottomDrawer.close();
               }
           }
           ...
       }
    }
}
