QML 转发器项目高亮处理
QML repeater item highlight handling
我已经实现了以下部分
{
id: idLeftArrow
.
.
.
.
}
Row
{
id: idIpEditModeItem
anchors.left: idLeftArrow.right
visible: true
Repeater
{
id: idIpHighlightRepeater
model: 12
Text
{
id: idDigits
text: "0"
font.pointSize: 10
color: "yellow"
}
}
}
Image
{
id: idIpHiglight_Image
width: editModeIPWidth
height: editModeIPHeight
x: idIpHighlightRepeater.itemAt(ipCurrSelectedDigitIndex).x
y: idIpHighlightRepeater.itemAt(ipCurrSelectedDigitIndex).y
visible: false
source: "focus.png"
}
这里我得到这样的输出
但是我想要这样的输出(每个字符之间会有一个空隙)
我还有一个 idIpHiglight_Image 用于突出显示每个数字。启动时我需要这样的输出
但在我的例子中,突出显示没有设置到正确的位置。我得到这样的输出
谁能帮我把输出设置成这样:
此外,在每次左右按键时,我需要将光标正确移动到 next/previous 位。
我写的代码像
onIpCurrSelectedDigitIndexChanged:
{
if( idIpHighlightRepeater.count == ipCurrSelectedDigitIndex)
{
ipCurrSelectedDigitIndex = 0
}
else if( 0 > ipCurrSelectedDigitIndex)
{
ipCurrSelectedDigitIndex = idIpHighlightRepeater.count - 1
}
}
执行代码后,出现类似
的错误
[W] (qrc:/common/qml/controls/CustomItem.qml:120) qrc:/common/qml/controls/EditListItem.qml:120: TypeError: Type error
[W] (qrc:/common/qml/controls/CustomItem.qml:119) qrc:/common/qml/controls/EditListItem.qml:119: TypeError: Type error
这是我收到上述错误的行
我会为数字和分隔符做 2 个不同的组件,像这样:
import QtQuick 2.12
import QtQuick.Window 2.12
Window {
id: main
visible: true
width: 600
height: 400
Component {
id: number
Text
{
text: "0"
font.pointSize: 16
color: "yellow"
padding: 5
Rectangle {
anchors.fill: parent
color: "transparent"
border { width: 3; color: "orange" }
visible: itemIndex == itemSelected
}
}
}
Component {
id: delimeter
Text
{
text: "."
font.pointSize: 16
color: "yellow"
}
}
Rectangle
{
id: rect
property int selected: -1;
color: "black"
anchors.centerIn: parent
width: layout.width
height: layout.height
Row {
id: layout
Repeater
{
id: repeater
model: 15
delegate: Loader {
id: loader
property int itemSelected: rect.selected;
property int itemIndex: index;
sourceComponent: ((index + 1) % 4 === 0) ? delimeter : number
}
}
}
}
Timer {
interval: 1000
repeat: true
running: true
onTriggered: {
if(rect.selected >= 15)
rect.selected = 0;
else
rect.selected ++;
}
}
}
结果:
