【问题描述】:
我是 qml 的新手,我需要编写一个简单的列表,其中包含 3 列和未定义的行数,使用 tableview 显示日志的输出。第一列显示类型(错误、警告、信息)。根据此关键字,我需要更改该行的颜色。我找到了可以更改所有行颜色的代码,但不能单独更改数据内容。这是我的出发点:
import QtQuick 2.13
import QtQuick.Window 2.11
import QtQuick.Layouts 1.3
import QtQuick.Controls 2.4
import QtQuick.Controls 1.4 as QtC1
import QtQuick.Dialogs 1.2
ApplicationWindow {
id: applicationWindow
visible: true
width: 640
height: 480
title: qsTr("Log")
ListModel {
id: listModel
ListElement { category: 'warning'; type: "DEVICE IN USE"; comment: "Device with ID: PS-0002 is in use by Line with ID: L-0001A" }
ListElement { category: 'error'; type: "DEVICE IS OFFLINE"; comment: "Cannot reach device with ID: PS-0006 IP: 192.169.0.112 Port: 788" }
ListElement { category: 'info'; type: "DEVICE STATUS"; comment: "Device PS-00013 is ready for use." }
ListElement { category: 'info'; type: "DEVICE STATUS"; comment: "Device PS-00014 is ready for use." }
ListElement { category: 'info'; type: "DEVICE STATUS"; comment: "Device PS-00015 is ready for use." }
ListElement { category: 'info'; type: "DEVICE STATUS"; comment: "Device PS-00016 is ready for use." }
}
ColumnLayout
{
anchors.fill: parent
transformOrigin: Item.Center
Label {
id: logLabel
Layout.alignment: Qt.AlignHCenter | Qt.AlignTop
font.pixelSize: 22
text: qsTr("Summary")
Layout.topMargin: 13
}
QtC1.TableView {
id: tv
Layout.fillHeight: true
Layout.preferredHeight: 18
Layout.preferredWidth: 9
Layout.fillWidth: true
rowDelegate: Rectangle {
color: styleData.value ? "blue":"white"
}
/* Create columns */
QtC1.TableViewColumn
{
id: tv_category
horizontalAlignment: Text.AlignLeft
role: qsTr("category")
title: qsTr("Category")
width: 100
}
QtC1.TableViewColumn
{
id: tv_type
horizontalAlignment: Text.AlignLeft
role: qsTr("type")
title: qsTr("Type")
width: 100
}
QtC1.TableViewColumn
{
id: tv_comment
horizontalAlignment: Text.AlignRight
role: qsTr("comment")
title: qsTr("Comment")
width: contentWidth
}
model: listModel
}
}
}
任何帮助将不胜感激。

您可以使用here中提到的QAbstractModel。对于 category,commetn... 标题更改颜色很容易,但是对于每个单元格,如果我没记错的话,您应该使用 QAbstractModel
