我正在尝试在按钮触发操作结束之前更新属性和GUI。
我觉得这应该很简单，但是我错过了File "C:\Users\constantinos\AppData\Local\Programs\Python\Python37-32\lib\site-packages\graphviz\files.py", line 188, in render
rendered = backend.render(self._engine, format, filepath, renderer, formatter)
File "C:\Users\constantinos\AppData\Local\Programs\Python\Python37-32\lib\site-packages\graphviz\backend.py", line 183, in render
run(cmd, capture_output=True, check=True, quiet=quiet)
File "C:\Users\constantinos\AppData\Local\Programs\Python\Python37-32\lib\site-packages\graphviz\backend.py", line 150, in run
raise ExecutableNotFound(cmd)
graphviz.backend.ExecutableNotFound: failed to execute ['dot', '-Tpdf', '-O', 'iris'], make sure the Graphviz executables are on your systems' PATH
命令或其他内容。
部分代码如下：
update按下按钮时，item1 = Property(Str, depends_on = ['button1'])
button1 = Button('Perform Action')
myview = View(Item('button1'), Item('item1'))
def _get_item1(self):
return somefunction()
def _button1_fired(self):
dosomething1()
dosomething2()
将更改dosomething1()的输出。 somefunction()会将dosomething2()的输出更改为其他内容。但是，运行此命令时，GUI将仅在somefunction()完成后更新item1。
是否可以在两个_button1_fired函数之间插入方法或命令，以使GUI“实时”更新
