General and Desktop

Ok. Thanks for your help.

Many thanks for your, help!

This is the link http://doc.qt.nokia.com/latest/itemviews-frozencolumn.html It worked in my application. Thanks

[quote author="mlong" date="1311704016"]Edit: Wow. Completely didn't see the last half of your last post (or the [Solved] in the title). I guess I got too excited about figuring out the problem. :-) I need to start getting more sleep, I think. [/quote] Haha, it's fine, I do that quite a bit too at times. :D

Good to see you solved it. Note that you're going to have to take into account the endianness of the system when you type-cast. The QDataStream solution passes that responsibility to Qt. You specify that the file data is stored in little endian format (unsigned short i = 1; memory maps to 0x0100), but if you use this solution on a big endian system (unsigned short i = 1; memmaps to 0x0001) you're going to see weird results all over again. I don't know if you're going to run into this, but take note of it in any case.

Super, thanks!

Finally, I solved this issue with a workaround. My guess is that each time a QComboBox gets the editable state, an internal QLineEdit is created, when it gets not editable the QLineEdit is destroyed (test the lineEdit() function to understand). But each time the QLineEdit is created, the stylesheet is lost, I guess beacause it is not saved in the QComboBox widget. So, my workaround has been to reimplement the setEditable(bool editable) function. When editable is true, I reapply the stylesheet to the QComboBox. The stylesheet is accessible by the styleSheet() function, if it has been applied to the specific widget. Otherwise, if it has been globally applied to the QApplication, it can be accessed by including <QApplication> and calling qApp->styleSheet(). This would be worth to be reported as a bug, but I don't know how to do it.

Update: this all seems to work correctly if I build my own Qt libs from sources...

Because I'm working in PyQt, libpcre is not available. Python native re support also lacks \p\N and has other Unicode deficiencies. However there is a good extension regex package ("regex":http://pypi.python.org/pypi/regex) with rather complete Unicode support. The difficulty that I see as a [Py]Qt newbie is in working on the one hand with a QPlainTextEditor and text cursor objects, and on the other with Python-based regex matching. Constantly crossing between the world of the editor document and the world of Python u"strings" looks like a very fruitful way to create confusion and mistakes. Comment?

iv written what QT needs to do a basic 3d graphics render but for some reason i just keep getting errors ??? and these errors are just horrid ones that no one can figure out heres what i put i know theres some dots missing but i really dont understand what the point of it is maybe for digits?? Or something whateva but the point is it wont work no matter how many ways i try to do it even with dots! :( maybe because im placing it within some other code?? but that shouldnt effect it at all if the syntax was correct on this piece of code below, its all very confusing and i really would apperciate it if someone could guide me in the right direction and do it in a detailed way :) so i can learn from it @ class opengl : public QGLWidget { Q_OBJECT public: opengl(QWidget *parent) : QGLWidget(parent) {} protected: void initializeGL() { glClearColor(0.0, 0.0, 0.0, 0.0); glEnable(GL_DEPTH_TEST); } void resizeGL(int w, int h) { glViewport(0, 0, (GLint)w, (GLint)h); glFrustum(); } void paintGL() glRotatef(); glMaterialfv(); glBeing(GL_QUADS); glVertex3f(); glEnd(); }; @

I have put the whole imageformats plugin folder, the "imageformats" folder, into the program folder and the problem is solved. Thank you very much. p.s.: The images are arbitrary on the harddisk, not included in src. I used a filedialog in code to find the image files.

tgone.start(); does a reset or not? Anyway the distance between 1st ad 2nd run is to big...a bug?

Its working fine...after the usuage of QStackedWidget..... thanks for your valuable input.........

"Kaspersky Lab forum":http://forum.kaspersky.com/index.php?showtopic=175881 says its a It is a behavioral detection!

Hi seg_fault, some general info: The deleting is not due to layouts directly, they just do something for you, that you could also do on your own :-) The magic here is parent/child relationship. All QObject derived classes may have a parent. All widgets have a parent unless they are top level. An QObject derived class deletes all children during it's own destruction. Now comes the layout into the game: The layout reparents the widgets so they have a parent which is responsible for the lifetime of the object. A spacer (which is no widget) belongs to the layout, so the layout deletes it. and a layout belongs to a layout or a widget, so they are also automatically deleted. Summary: Only delete top level items directly, or widgets, you definitely need destructed. They will destroy all child objects implicit.

Hi Seeajay, This is a forum about programming with C++ and the Qt framework. In what way is your question related to that? Do you want to make a program that uses web cam? If not I suggest to use google to search the web for such an app.

Can you please edit the title of this question and place [SOLVED] at the beginning.

Sorry, when I can be a "CWinApp", I really mean have the entry be WinMain instead of plain ol' main.
