QML弹出窗口组件，灯箱效果、动画效果，可拖拽 核心思路：一个mask层，一个最顶层，都用rectangle，禁止事件穿透 使用 Popup { id: popup width: 200; height: 300 x: 200; y:100 z: 101 opacity: 0.8 visible: false; radius: 5 ... } popup.showMask = chk.checked; popup.animationType = 'size'; popup.show(); 注意 使用位移动画不能用anchors定位方式核心代码 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 Rectangle { id: root width: 100 height: 200 color: 'lightblue' z:100 transformOrigin: Item.Center // 无效 // 公有属性 property bool showMask : false; property string animationType : 'none'; property int duration : 500 property int easingType : Easing.OutBounce // 私有属性 property int innerX; property int innerY; property int innerWidth; property int innerHeight; property double innerOpacity; //------------------------------ // 事件 //------------------------------ // 属性备份一下，避免动画对属性进行变更 Component.onCompleted: { save(); } function show() { reset(); switch (animationType) { case "fade": animFadeIn.start(); break; case "focus": animFocusIn.start(); break; case "width": animWidthIncrease.start(); break; case "height": animHeightIncrease.start(); break; case "size": animBig.start(); break; case "flyDown": animInDown.start(); break; case "flyUp": animInUp.start(); break; case "flyLeft": animInLeft.start(); break; case "flyRight": animInRight.start(); break; default: this.visible = true; } } function hide() { switch (animationType) { case "fade": connector.target = animFadeOut; animFadeOut.start(); break; case "focus": connector.target = animFocusOut; animFocusOut.start(); break; case "width": connector.target = animWidthDecrease; animWidthDecrease.start(); break; case "height": connector.target = animHeightDecrease; animHeightDecrease.start(); break; case "size": connector.target = animSmall; animSmall.start(); break; case "flyDown": connector.target = animOutUp; animOutUp.start(); break; case "flyUp": connector.target = animOutDown; animOutDown.start(); break; case "flyLeft": connector.target = animOutRight; animOutRight.start();break; case "flyRight":connector.target = animOutLeft; animOutLeft.start(); break; default: close(); } } // 动画结束后调用的脚本 Connections{ id: connector target: animInDown onStopped: close() } //------------------------------ // 辅助方法 //------------------------------ function getRoot(item) { return (item.parent !== null) ? getRoot(item.parent) : item; } function save() { innerX = root.x; innerY = root.y; innerWidth = root.width; innerHeight = root.height; innerOpacity = root.opacity; console.log("x=" + innerX + " y="+innerY + " w=" + innerWidth + " h="+innerHeight); } function reset() { root.x = innerX; root.y = innerY; root.width = innerWidth root.height = innerHeight; root.opacity = innerOpacity; root.scale = 1; connector.target = null; mask.visible = showMask; root.visible = true; } // 立即关闭 function close() { mask.visible = false; root.visible = false; log(); } function log() { console.log("x=" + x + " y="+y + " w=" + width + " h="+height); } //------------------------------ // 遮罩 //------------------------------ // 禁止事件穿透 MouseArea{ anchors.fill: parent; onPressed:{ mouse.accepted = true } drag.target: root // root可拖动 } // 灯箱遮罩层 Mask{ id: mask visible: false } //------------------------------ // 动画 //------------------------------ // fadeIn/fadeOut PropertyAnimation { id:animFadeIn target: root duration: root.duration easing.type: root.easingType property: 'opacity'; from: 0; to: root.innerOpacity } PropertyAnimation { id: animFadeOut target: root duration: root.duration easing.type: root.easingType property: 'opacity'; from: root.innerOpacity; to: 0 } ... }
