我有一个QML文本输入元素,就像这样:
TextBox.qml
FocusScope {
id: focusScope
property int fontSize: focusScope.height -30
property int textBoxWidth: parent.width * 0.8
property int textBoxHeight: 45
property string placeHolder: 'Type something...'
property bool isUserInTheMiddleOfEntringText: false
width: textBoxWidth
height: textBoxHeight
Rectangle {
width: parent.width
height: parent.height
border.color:'blue'
border.width: 3
radius: 0
MouseArea {
anchors.fill: parent
onClicked: {
focusScope.focus = true
textInput.openSoftwareInputPanel()
}
}
}
Text {
id: typeSomething
anchors.fill: parent; anchors.rightMargin: 8
verticalAlignment: Text.AlignVCenter
text: placeHolder
color: 'red'
font.italic: true
font.pointSize: fontSize
MouseArea {
anchors.fill: parent
onClicked: {
focusScope.focus = true
textInput.openSoftwareInputPanel()
}
}
}
MouseArea {
anchors.fill: parent
onClicked: {
focusScope.focus = true
textInput.openSoftwareInputPanel()
}
}
TextInput {
id: textInput
anchors {
right: parent.right
rightMargin: 8
left: clear.right
leftMargin: 8
verticalCenter: parent.verticalCenter
}
focus: true
selectByMouse: true
font.pointSize: fontSize
}
Text {
id: clear
text: '\u2717'
color: 'yellow'
font.pointSize: 25
opacity: 0
visible: readOnlyTextBox ? false : true
anchors {
left: parent.left
leftMargin: 8
verticalCenter: parent.verticalCenter
}
MouseArea {
anchors.fill: parent
onClicked: {
textInput.text = ''
focusScope.focus = true;
textInput.openSoftwareInputPanel()
}
}
}
states: State {
name: 'hasText'; when: textInput.text != ''
PropertyChanges {
target: typeSomething
opacity: 0
}
PropertyChanges {
target: clear
opacity: 0.5
}
}
transitions: [
Transition {
from: ''; to: 'hasText'
NumberAnimation {
exclude: typeSomething
properties: 'opacity'
}
},
Transition {
from: 'hasText'; to: ''
NumberAnimation {
properties: 'opacity'
}
}
]
}
我想给这个文本框添加像谷歌搜索一样的自动完成和建议功能。自动完成从数据库获取数据,数据库通过pyside SLOT(或c++ slot)返回一个字典列表。
我该如何实现这项工作?
