<h3>1、测试修改窗口属性</h3>
|
||||||
|
windowTitle 是Qt窗口本身的属性, 当标题被修改后会触发本身的windowTitleChanged信号<br>
|
||||||
|
<input type="text" id="title" placeholder="请输入标题" />
|
||||||
|
<p></p>
|
||||||
|
<button onclick="javascript:Bridge.windowTitle = document.getElementById('title').value;">测试修改标题</button>
|
||||||
|
|
||||||
|
<h3>2、调用Python中的方法callFromJs</h3>
|
||||||
|
callFromJs(str) 函数是由Python代码中定义, 通过@pyqtSlot(str)装饰器暴露出来<br>
|
||||||
|
<button onclick="javascript:Bridge.callFromJs('test');">Bridge.callFromJs('test')</button>
|
||||||
|
|
||||||
|
<h3>3、发送自定义信号</h3>
|
||||||
|
点击底部的按钮将会发送customSignal信号出来，网页中收到该信号将会在下面日志框输出内容<br>
|
||||||
|
|
||||||
|
