General and Desktop

For those who might be interested I figured out a simple way : Drawing outside the paint event in a picture with alpha enabled Painting the picture on top of the video. Which means before displaying the actual video, I paint the overlay image on the video image. Now I dropped superposition of child widgets and everything. The advantage is that I can create the overlay while the application is busy doing some other things.

As a side node, the crash comes from here: @ MyLine::MyLine(const MyLine &obj){ text = obj.text; startTime = obj.startTime; endTime = obj.endTime; } @ You copy the pointer. and in the destructor of both objects, you then destroy it (this and obj)

I guess you want to have your tabPostion at West.

[quote author="ZapB" date="1310040148"]You need to use a more specific selector to ensure that only your QMainWindow selects that particular syle. Something like this stylesheet snippet should do it: @ QMainWindow { background-color: rgb(254, 255, 247); } @ You can set this directly on yoru mainwindow via the ui file. Just right-click on the main window in design mode of creator and select "Change Stylesheet..." and past the above in and hit Apply.[/quote] The reason why this is needed is that style sheets are also derived / forwarded to shildren. And you set the properties in a generic way.

this post is old, but not too much to say thank you! :D

you could also use a QList<Field*> or a QVector<Field*> then you dont have to take care about copying. you can implement a destructor to delete the Widget in Field, and delete the field when you dont need it anymore

Thanks a lot for your i/p..

In Qt there is only qsortfilterproxymodel ... at this moment... ;) But other developers can make subclasses too. For instance when you program for kde. So in that sense the sentence is correct.

nah, it's because another (iphone) application writes a binary plist file that i'm trying to read (via dropbox) so it can be read by windows and linux machines as well going into the qt sources won't help me much because in the platform limitations (http://doc.qt.nokia.com/stable/qsettings.html#platform-limitations) of QSettings it starts with: "On Mac OS X, the CFPreferences API used by QSettings expects..." so that CFPreferences API won't be available on non mac platforms. using ini files would have been great if i controlled the iphone application, but i don't. I'll have another look when i finish my mac version first. thanks all for thinking along. it's much appreciated !!

If you are sure you want to go down this route then I think probably your best option is to subclass QTableView and override the sizeHint stuff so that the table returns sizehints suitable for the contents they are showing. The Qt layout system should then take care of the rest of it for you. That is not to say that calculating suitable size hints will be easy. You will need to query things like number of rows and their sizes (or are they all the same size), style metrics (since different styles have different size requirements), margins, font sizes etc.

[quote author="Andre" date="1310028072"] Fine. So that works ok then? [/quote] Jepp, no problems. [quote] Yes, there is. Use ::setSelectionBehavior(QAbstractItemView::SelectRows) on your view. [/quote] Gracias.

I have a guess... I used Qt4SyntaxHighlighter that reads a css file and applies highlighting on the content. I didn't set any font in that css file (just colors). Is this related to syntax highlighter ?

Thank you Rahul Pandey. I ll give it a try n get back to u. Regards, Vijaeendra Simha

Thanks, but I mean a Qt define already defined by Qt framwork. I found this that do the works: @ QMAKE_POST_LINK = copy $${QMAKE_LIBDIR_QT}\Qt*.dll ..\bin @

Try with /Applications/Safari.app/Contents/MacOS/Safari

are the function keys enabled on your keyboard? on mac you can switch between the function keys and the special tasks (like f12 is making sound louder) alternativly you can try QKeySequence(Qt::Shift + Qt::Key_F12)

I found solution I made my horizontal headers only digits in data role, and all text in tool tip role, but vertical header leave with text(because it's actually duplicates horizontal header) . So now it has a nice look. Andre, thanks for the help.

renato.filho renato.filho> Thanks for your answer, but I think you are talking about "repeat" function. I don't have any problems with that. I'm interested in "Replay Gain":http://en.wikipedia.org/wiki/Replay_Gain My current solution is to catch trackChanged signal (I will probably switch to finished() signal) and then I adjust the volume in dB according to Replay Gain values in tags.

Thanks Andre and all to clearly the concept i guess i understand it fully now
