再上一个

使用鼠标控制字体的显示
import QtQuick 2.2
import QtQuick.Controls 1.1

{
GradientStop { position: 0.0; color: '#FF4444' }
GradientStop { position: 1.0; color: "blue" }
}
// 边框颜色
border.color: "red"
radius: 8
Text
{
id: text
text: "The quick brown fox"
color: "#303060"
anchors.centerIn: parent
font.family: "Ubuntu"
font.pixelSize: 24
elide: Text.ElideMiddle

}

import QtQuick 2.2
import QtQuick.Controls 1.1

//here
property int spacePresses: 0

onTextChanged: console.log("text changed to:", text)
focus: true
Keys.onSpacePressed:
{
increment()
}
Keys.onEscapePressed:
{
label.text = ''
}
//! 这是一个js函数
function increment()
{
spacePresses = spacePresses + 1
}
}
import QtQuick 2.2
import QtQuick.Controls 1.1
Rectangle
{
Image
{
anchors.fill: parent
id: background
source: "background.png"
}
width: 360
height: 360
Text
{
anchors.centerIn: parent
text: "你好世界,点击鼠标退出程序"
}
MouseArea
{
anchors.fill: parent
onClicked:
{
Qt.quit();
}
}
}
基本代码如下:
import QtQuick 2.2
import QtQuick.Controls 1.1
Image
{
id: root
source: "background.png"
}
这个是使用给定图形填充背景，
如果使用多个图形嵌套，做法如下:
import QtQuick 2.2
import QtQuick.Controls 1.1
Image
{
id: root
source: "background.png"
Image
{
id: head
source: "head.png"
anchors.centerIn: parent
anchors.verticalCenterOffset: 20
}
}
当然可以再加上旋转
import QtQuick 2.2
import QtQuick.Controls 1.1
Image
{
id: root
source: "background.png"
Image
{
id: head
width: 48
height: 48
source: "head.png"
anchors.centerIn: parent
anchors.verticalCenterOffset: 20
MouseArea
{
anchors.fill: parent
onClicked: head.rotation += 9
}
}
}
加上动画可以让旋转更加平滑点，如下:
import QtQuick 2.2
import QtQuick.Controls 1.1
Image
{
id: root
source: "background.png"
Image
{
id: head
width: 48
height: 48
source: "head.png"
anchors.centerIn: parent
anchors.verticalCenterOffset: 20
MouseArea
{
anchors.fill: parent
onClicked: head.rotation += 90
}
Behavior on rotation
{
NumberAnimation
{
duration: 600
}
}
}
}
一个Item对应一个场景，提供隐藏或显示场景即可切换，如下:
import QtQuick 2.2
import QtQuick.Controls 1.1
ApplicationWindow
{
visible: true
width: 480
height: 360
title: "Hello World"
Item
{
id: scene_1
visible: true
anchors.fill: parent
Text
{
anchors.centerIn: parent
textFormat: Text.RichText
text: "<h1><font color=red>这是第一个场景</color></h1>"
}
MouseArea
{
anchors.fill: parent
onClicked:
{
scene_1.visible = false;
scene_2.visible = true;
scene_3.visible = false;
}
}
}
Item
{
id: scene_2
visible: false
anchors.fill: parent
Text
{
anchors.centerIn: parent
textFormat: Text.RichText
text: "<h1><font color=green>这是第二个场景</color></h1>"
}
MouseArea
{
anchors.fill: parent
onClicked:
{
scene_2.visible = false;
scene_1.visible = false;
scene_3.visible = true;
}
}
}
Item
{
id: scene_3
visible: false
anchors.fill: parent
Text
{
anchors.centerIn: parent
textFormat: Text.RichText
text: "<h1><font color=black>这是第三个场景</color></h1>"
}
MouseArea
{
anchors.fill: parent
onClicked:
{
scene_1.visible = true
scene_2.visible = false;
scene_3.visible = false;
}
}
}
}
如下:
sql += "',N'";
sql += desc1;
sql += "',N'";
sql += desc2;
sql += "',N'";
sql += desc3;
sql += "');select @@identity;";
OleDbConnection conn = getOleDbConntion();
OleDbCommand cmd = new OleDbCommand(sql, conn);
conn.Open();
OleDbDataReader reader = cmd.ExecuteReader();
reader.Read();
string index = reader.GetValue(0).ToString();
conn.Close();
return index;
}
Date.prototype.format = function(format) {
var args = {
"M+": this.getMonth() + 1,
"d+": this.getDate(),
"h+": this.getHours(),
"m+": this.getMinutes(),
"s+": this.getSeconds(),
"q+": Math.floor((this.getMonth() + 3) / 3),

};
if (/(y+)/.test(format))

for (var i in args) {
var n = args[i];
if (new RegExp("(" + i + ")").test(format))
format = format.replace(RegExp.$1, RegExp.$1.length == 1 ? n : ("00" + n).substr(("" + n).length));
}
return format;
};
