Beneath the combo boxes we added a couple more widgets to hold the destination file name – a button to select the file and a disabled line edit field to show the location. 在组合框下面,我们添加了更多小部件,用于保存目的文件的名称&一个按钮用于选择文件,以及一个禁用的线编辑字段用于显示位置。
Now add a Line Edit(LE) widget from the Inputs list and click on the'enabled'property in the bottom left panel to disable it. 现在从Inputs列表中添加一个LineEdit小部件,然后点击左下方面板中的“enabled”属性以禁用它。
As the Line Edit(LE) widget is interactive – by default, the user can type into it – we want to disable this feature and only use the widget to display the source location of the file we want to convert. 由于LineEdit小部件是交互式的即默认情况下,用户可以在里面输入内容我们想禁用这项功能,而只使用它来显示我们要转换文件的源位置。
The last line shown above prompts you to either edit ( E ) the step parameters or cancel ( C ) to exit the step. 以上显示的最后一行,提示用户或者编辑(E)该步骤参数,或者取消(C)退出该步骤。
Select the lines that you want to run. To edit a line, click it, and then click Edit. 请选择要运行的命令行。要编辑命令行,请单击它,然后单击编辑。
