A string matching the window class (WM_CLASS property) The window class can be found out by running'xprop _BAR_ grep WM_CLASS 'and clicking on a window (use either both parts separated by a space or only the right part). NOTE: If you specify neither window title nor window class, then the very first window to appear will be taken; omitting both options is NOT recommended.
Teaghrán comhoiriúnach d' aicme na fuinneoige (airí WM_ CLASS) Is féidir aicme na fuinneoige a fháil tríd an ordú 'xprop _BAR_ grep WM_ CLASS' a rith agus fuinneog a chliceáil (úsáid an dá chuid le spás eatarthu nó an chuid ar dheis amháin). NÓTA: Mura sonraíonn tú teideal na fuinneoige ná aicme na fuinneoige, tógfar an chéad fhuinneog a thaispeántar; NÍ moltar duit an dá rogha a fhágáil ar lár.
