屏幕输入/输出

从「工具 – 宏 - 运行宏...」菜单运行 Python 宏时,Python 标准输出文件不可用。展示模块的输出内容需要 Python 交互式控制台。Python shell 提供 input()print()repr()str() 等功能。

LibreOffice msgbox Python module proposes a msgbox() method that is illustrated in Creating Event Listeners and Creating a dialog handler example pages.


LibreOffice Basic 提供 InputBox()Msgbox()Print() 屏幕输入/输出函数。现有的 Python 替代品有的依赖 LibreOffice API 抽象窗口工具集 (Abstract Windowing Toolkit),有的依赖 Python 向 Basic 的函数调用。后者提供有意接近 Basic 的语法,同时使用 Python 模块与 Basic 模块。API 脚本框架被用于执行 Basic、BeanShell、JavaScript 以及 Python 的跨语言函数调用。

Python 语法:

MsgBox(txt, buttons=0, title=None)

InputBox(txt, title=None, default=None)

Print(txt)

示例:

>>> import screen_io as ui

>>> reply = ui.InputBox('Please enter a phrase', title='Dear user', defaultValue="here..")

>>> rc = ui.MsgBox(reply, title="Confirmation of phrase")

>>> age = ui.InputBox('How old are you?', title="Hi")

>>> ui.Print(age)

安装:

        def InputBox(prompt: str, title='LibreOffice', defaultValue='') -> str:
            """ 在对话框中显示提示,用户可以在对话框内输入文字。"""
            xScript = _getScript("_InputBox")
            res = xScript.invoke((prompt,title,defaultValue), (), ())
            return res[0]
        
        def Print(message: str):
            """在对话框中输出指定字符串或数字表达式。"""
            xScript = _getScript("_Print")
            xScript.invoke((message,), (), ())
        
        import uno
        from com.sun.star.script.provider import XScript
        def _getScript(script: str, library='Standard', module='uiScripts') -> XScript:
            sm = uno.getComponentContext().ServiceManager
            mspf = sm.createInstanceWithContext("com.sun.star.script.provider.MasterScriptProviderFactory", uno.getComponentContext())
            scriptPro = mspf.createScriptProvider("")
            scriptName = "vnd.sun.star.script:"+library+"."+module+"."+script+"?language=Basic&location=application"
            xScript = scriptPro.getScript(scriptName)
            return xScript
    
note

MsgBox and InputBox methods from the Basic service included in the ScriptForge libraries call directly their native Basic counterparts.

The Alternative Python Script Organizer (APSO) extension offers a msgbox() function out of its apso_utils module.
