[commonqt-devel] Question abot CommonQt examples

[Rujia Liu]

Dear all,

I've just successfully installed CommonQt on Windows XP, and is able to run
both qt-conv and tutorial-14. However, I have two questions.

1. In qt-conv example, if I run (main t) instead of (main), I got "Class
not found: QApplication" error. But when i type (find-qclass "QApplication"
t) in REPL, i got 1796.

2. in tutorial-14 example, I had to comment out two lines:
  ;(with-objects ((rect (#_new QRect -35 -35 70 70)))
  ;  (#_drawPie painter rect 0 (* 90 16)))

Otherwise I'll get:
#<THREAD "main thread" RUNNING {23DA8A69}>:
  No applicable method drawPie found on #<QPainter 0x021705D0> with
arguments (#
<QRect 0x02174AB8>

0


(
*

90

16))

I'm using Qt 4.8.5 library for vs2008 and compiled smokegen/smokeqt with
vs2008 express (without SP1)

I used quicklisp to install commonqt yesterday, and is running qt-conv this
way (ommited the output of the first 2 commands):

E:\>sbcl
* (require 'qt)
* (load "qt-conv.lisp")
* (qt-conv:main t)

debugger invoked on a SIMPLE-ERROR in thread
#<THREAD "main thread" RUNNING {23DA8A69}>:
  Class not found: QApplication

Type HELP for debugger help, or (SB-EXT:EXIT) to exit from SBCL.

restarts (invokable by number or by possibly-abbreviated name):
  0: [ABORT] Exit debugger, returning to top level.

(QT:FIND-QCLASS "QApplication" T)
0] 0

* (qt-conv:main) ;; then no error occurred. qt-conv will run perfectly

Thanks in advance!
