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
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 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 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 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: parent.modelData
Banner is a simple example showing how to create a banner using a row of text types and a NumberAnimation .
Img tag
shows different ways of displaying images in text objects using the
<img>
标签。
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) => {
line.width = width / 2 - main.margin
if (line.y + line.height >= height) {
line.y -= height - main.margin
line.x = width / 2 + main.margin
}
if (line.isLast) {
lastLineMarker.x = line.x + line.implicitWidth
lastLineMarker.y = line.y + (line.height - lastLineMarker.height) / 2
}
}
