After a short introduction, we will begin an in-depth investigation of the core concept of PyQt: signals and slots. String handling and object creation are the topics of the next two chapters. The basic layout of the Qt class library will be explored, illustrated with trivial and not-so-trivial examples. Finally, we explain how to create GUI designs using the designer module.</P></DIV><DIVCLASS="TOC"><DL><DT><B>Table of Contents</B></DT><DT>6. <AHREF="c1036.htm">Qt Concepts</A></DT><DT>7. <AHREF="c1267.htm">Signals and Slots in Depth</A></DT><DT>8. <AHREF="c2029.htm">String Objects in Python and Qt</A></DT><DT>9. <AHREF="c2341.htm">Python Objects and Qt Objects</A></DT><DT>10. <AHREF="c2591.htm">Qt Class Hierarchy</A></DT><DT>11. <AHREF="c4079.htm">Qt Designer, BlackAdder and uic</A></DT></DL></DIV></DIV></DIV><DIVCLASS="NAVFOOTER"><HRALIGN="LEFT"WIDTH="100%"><TABLESUMMARY="Footer navigation table"WIDTH="100%"BORDER="0"CELLPADDING="0"CELLSPACING="0"><TR><TDWIDTH="33%"ALIGN="left"VALIGN="top"><AHREF="x1024.htm"ACCESSKEY="P">Prev</A></TD><TDWIDTH="34%"ALIGN="center"VALIGN="top"><AHREF="book1.htm"ACCESSKEY="H">Home</A></TD><TDWIDTH="33%"ALIGN="right"VALIGN="top"><AHREF="c1036.htm"ACCESSKEY="N">Next</A></TD></TR><TR><TDWIDTH="33%"ALIGN="left"VALIGN="top">If all else fails</TD><TDWIDTH="34%"ALIGN="center"VALIGN="top"> </TD><TDWIDTH="33%"ALIGN="right"VALIGN="top">Qt Concepts</TD></TR></TABLE></DIV></BODY></HTML>⌨️ 快捷键说明
