[PyQt] [SIP]MD5 openssl
Hello Recently I tried to use my c++ library in Python using SIP. In SIP configuration file I added some extra libraries like QtGui,fftw3 and ssl. Compilation and linking pass without any warnings or errors: g++ -c -pipe -fPIC -O2 -Wall -W -DNDEBUG -I. -I/usr/include/python2.7 -o sipmd5testcmodule.o sipmd5testcmodule.cpp g++ -c -pipe -fPIC -O2 -Wall -W -DNDEBUG -I. -I/usr/include/python2.7 -o sipmd5testmd5test.o sipmd5testmd5test.cpp g++ -c -pipe -fPIC -O2 -Wall -W -DNDEBUG -I. -I/usr/include/python2.7 -o md5test.o md5test.cpp g++ -Wl,--hash-style=gnu -Wl,--as-needed -shared -Wl,--version-script=md5test.exp -o md5test.so sipmd5testcmodule.o sipmd5testmd5test.o md5test.o -lssl But when I try to import library: ImportError: ./md5test.so: undefined symbol: MD5 When I compiled my code and included it in c++ all worked fine. ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
Re: [PyQt] QLineEdit vs. menu keyboard shortcuts
from PyQt4.QtCore import * from PyQt4.QtGui import * import sys class Foo(QLineEdit): def keyPressEvent(self, event): print 'Foo keyPress', event.key(); sys.stdout.flush() QLineEdit.keyPressEvent(self, event) app = QApplication([]) window = QMainWindow() f = Foo() window.setCentralWidget(f) window.show() def do_action(): print 'action'; sys.stdout.flush() action1 = QAction('Action 1', f, triggered=do_action) action1.setShortcut(Qt.CTRL + Qt.Key_Z) action1.setShortcutContext(Qt.WidgetShortcut) For actions that should work all over the mainwindow, you should use Qt.WidgetWithChildren here. Oops, that line was an artifact of an earlier experiment. I actually tried every possible value for shortcutContext, none of them seem to make a difference. ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

Short answer: focus tricks won't work for me. I need the widget to be able to accept keyboard focus and respond to some keyboard shortcuts. Long answer: I guess this will require a complete specification of how my widget works. The widget appears to the user somewhat like a label displaying a number. If the user clicks and drags, the value will increase or decrease as the mouse is moved. By holding down modifier keys the user can adjust the speed with which the value changes. If the user clicks (but doesn't drag), the number is highlighted and a text editing cursor appears. The widget at this point behaves exactly like a QLineEdit (with a validator to force numeric values). When the user presses Enter or the widget loses focus, it reverts to its default appearance. If the widget has keyboard focus, but isn't in edit mode, the Up/Down arrow keys will nudge the value a small amount in either direction. I am implementing this as a subclass of QLineEdit, overriding mouse and keyboard events and throwing in some CSS to make it look nice. When the widget is in edit mode it's set to editable, otherwise it's set to non-editable. Now, when the widget is in its non-editable state, and the user hits Ctrl-Z, I want it to trigger the Undo action on the Edit menu. Unfortunately, QLineEdit intercepts the Ctrl-Z keystroke and does nothing (because it's not editable). I can't call clearFocus() at the end of the drag, because this would break the Up/Down arrow shortcuts. - Nathan ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
[PyQt] selecting an item in qtreeview
When using qtreewidget, I can use the itemClicked method to then call a def: self.treeWidget_iRulesList.itemClicked.connect(self.displayRule) However, I hit a wall in trying to pass data around this way, so I watched some tutorials on how to set up a model view and abstract the data from the GUI components. This involved switching from a treeWidget to a treeView. This works great in populating the tree, but now I don't know how to signal a clicked item and pass that item (and the tree parent it belongs to) to my displayRule def. Any thoughts? ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
