建立一个标签

创建标签 " " 用于输入

				
					{"blocks":"<xml xmlns=\"https://developers.google.com/blockly/xml\"><block type=\"Control_createLabel\"><value name=\"labelText\"><shadow type=\"text\"><field name=\"TEXT\"/></shadow></value></block></xml>"}
				
			

这积木允许用家点击标签元素内的文字。当标签元素被按下后,它会作出一些行动。

参数:

  • 显示设定:字串
  • 萤幕项目(非输入控制)
  • 输出: 萤幕项目

示例代码:

				
					{"blocks":"<xml xmlns=\"https://developers.google.com/blockly/xml\"><variables><variable>mainLayout</variable><variable>mainScreen</variable><variable>checkBox</variable><variable>labelWithText</variable></variables><block type=\"pxt-on-start\" x=\"0\" y=\"0\"><statement name=\"HANDLER\"><block type=\"variables_set\"><field name=\"VAR\">mainLayout</field><value name=\"VALUE\"><shadow type=\"math_number\"><field name=\"NUM\">0</field></shadow><block type=\"ScreenItem_createLayout\"/></value><next><block type=\"variables_set\"><field name=\"VAR\">mainScreen</field><value name=\"VALUE\"><shadow type=\"math_number\"><field name=\"NUM\">0</field></shadow><block type=\"Screen_create\"><value name=\"label\"><shadow type=\"text\"><field name=\"TEXT\">Main</field></shadow></value><value name=\"layout\"><block type=\"variables_get\"><field name=\"VAR\">mainLayout</field></block></value></block></value><next><block type=\"variables_set\"><field name=\"VAR\">checkBox</field><value name=\"VALUE\"><shadow type=\"math_number\"><field name=\"NUM\">0</field></shadow><block type=\"Control_createCheckbox\"/></value><next><block type=\"variables_set\"><field name=\"VAR\">labelWithText</field><value name=\"VALUE\"><shadow type=\"math_number\"><field name=\"NUM\">0</field></shadow><block type=\"Control_createLabel\"><value name=\"labelText\"><shadow type=\"text\"><field name=\"TEXT\">Check box</field></shadow></value><value name=\"inputControl\"><block type=\"variables_get\"><field name=\"VAR\">checkBox</field></block></value></block></value><next><block type=\"ScreenItem_Layout_setDirection\"><field name=\"direction\">FlexDirection.Row</field><value name=\"this\"><block type=\"variables_get\"><field name=\"VAR\">mainLayout</field></block></value><next><block type=\"ScreenItem_Layout_add\"><value name=\"this\"><block type=\"variables_get\"><field name=\"VAR\">mainLayout</field></block></value><value name=\"item\"><block type=\"variables_get\"><field name=\"VAR\">labelWithText</field></block></value><next><block type=\"ScreenItem_Layout_add\"><value name=\"this\"><block type=\"variables_get\"><field name=\"VAR\">mainLayout</field></block></value><value name=\"item\"><block type=\"variables_get\"><field name=\"VAR\">checkBox</field></block></value></block></next></block></next></block></next></block></next></block></next></block></next></block></statement></block></xml>"}
