Qt Quick 范例 - 文本

这是文本相关 QML 范例的集合。

文本 is a collection of small QML examples relating to text. Each example is a small QML file, usually containing or emphasizing a particular type or feature. You can run and observe the behavior of each example.

Hello

Hello shows how to change and animate the letter spacing of a Text type. It uses a sequential animation to first animate the font.letterSpacing property from 0 to 50 over three seconds and then move the text to a random position on screen:

            SequentialAnimation on font.letterSpacing {
                loops: Animation.Infinite;
                NumberAnimation { from: 0; to: 50; easing.type: Easing.InQuad; duration: 3000 }
                ScriptAction {
                    script: {
                        container.y = (screen.height / 4) + (Math.random() * screen.height / 2)
                        container.x = (screen.width / 4) + (Math.random() * screen.width / 2)
                    }
                }
            }

字体

字体 shows different ways of using fonts with the Text type. Simply by name, using the font.family property directly:

            font.family: "Times"

或使用 FontLoader 类型：

    FontLoader { id: fixedFont; name: "Courier" }

或使用 FontLoader and specifying a local font file:

    FontLoader { id: localFont; source: "content/fonts/tarzeau_ocr_a.ttf" }

or finally using a FontLoader and specifying a remote font file:

    FontLoader { id: webFont; source: "http://www.princexml.com/fonts/steffmann/Starburst.ttf" }

可用字体

可用字体 展示如何使用 Qt global object and a list view to display all the fonts available on the system. The ListView type uses the list of fonts available as its model:

        model: Qt.fontFamilies()

Inside the delegate, the font family is set with the modelData:

                font.family: modelData

Banner is a simple example showing how to create a banner using a row of text types and a NumberAnimation .

Img Tag

Img tag shows different ways of displaying images in text objects using the <img> 标签。

文本布局

文本布局 shows how to create a more complex layout for a text item. This example lays out the text in two columns using the onLineLaidOut handler that allows you to position and resize each line:

        onLineLaidOut: {
            line.width = width / 2  - (margin)
            if (line.y + line.height >= height) {
                line.y -= height - margin
                line.x = width / 2 + margin
            }
        }
