章節(jié)摘錄

版權(quán)頁：   插圖：   The "browse" button in Figure 10-7 pops up a file selection dialog just as the packdlg form did.Instead of an OK button,this dialog binds the Enter key-press event to kill the window and end the modalwait state pause; on submission, the name of the packed file is passed to the main function of the unpacker script shown earlier to perform the actual file scan process. Room forimprovement All of this works as advertised-by making command-line tools available in graphical form like this, they become much more attractive to users accustomed to the GUI way of life.We've effectively added a simple GUI front-end to command-line tools.Still, two aspects of this design seem prime for improvement. First, both of the input dialogs use common code to build the rows of their input forms, but it's tailored to this specific use case; we might be able to simplify the dialogs further by importing a more generic form-builder module instead.We met general form builder code in Chapters 8 and 9, and we'll meet more later-see the form.py module in Chapter 12 for pointers on further genericizing form construction. Second, at the point where the user submits input data in either form dialog,we've lost the GUI trail-the GUI is blocked, and messages are routed back to the console.The GUI is technically blocked and will not update itselfwhile the pack and unpack utilities run; although these operations are fast enough for my files as to be negligible,we would probably want to spawn these calls off in threads for very large files to keep the main GUI thread active （more on threads later in this chapter）. The console issue is more blatant: packer and unpacker messages still show up in the stdout console window, not in the GUI （all the filenames here include full directory paths if you select them with the GUI's Browse buttons, courtesy of the standard Open dialog）: C:\...\PP4E\Gui\5hellGui\temp> python ..\mytools.py list PP4E saolledtext list test Packer: packed.all （'spam.txt', 'ham.txt', 'eggs.txt'） packing: spam.txt packing: ham.txt packing: eggs.txt Unpacker: packed.all creating: spam.txt creating: ham.txt creating: eggs.txt.

編輯推薦

《Python編程(影印版)(第4版)(套裝共2冊)》針對該語言的主要應(yīng)用領(lǐng)域——系統(tǒng)管理、GUI和Web——做了深入講解，并且探索了它在數(shù)據(jù)庫、網(wǎng)絡(luò)、前端腳本撰寫層、文本處理和更多方面的使用。通過重點關(guān)注常用工具和庫，你將會對Python在實際現(xiàn)實世界里的編程有更深的理解。你將通過一種清晰和簡潔的方式——講解大量正確用法和常見慣例的例子——學(xué)會語言的語法和編程技巧?！禤ython編程(影印版)(第4版)(套裝共2冊)》針對3.x版本做了完全的更新，它探討了Python如何成為軟件開發(fā)工具，并且特別為此設(shè)計了很多代碼示例。
