qt - Qt4 how to add 16px/32px/... icons for my application? -

How can I set up my QT application? Do I have to provide 16px, 32px icon and so on? Or can QT automatically change their size to fit current needs?

EDIT: It appears that you click the window icon of the top-level window. Window icon can be set using QWidget :: setWindowIcon () , and set the default icon for new window by using QApplication :: setWindowIcon () Could. If your source image is of a high enough resolution, QT will automatically resize this icon to make itself fit for all events.

The description is in Qt, which includes information about setting up an embedded icon of AEM. File or OS X application.

visual studio 2010 - How to reinstall MVC 2 tools for VS2010? -



    I uninstalled ASP.Net MVC 2 device for Visual Studio 2010. How can I restore it? MVC2 downloads seem to include only the VS2008 device.   Whatever I said, says that MVC 2 has been included in VS2010, but the installation of an improvement did not fix it, and MVC 2 is not listed. Add VS2010 / Select a component in the Remove screen.      You will get your VS2010ToolsMVC2.msi VS2010 DVD under WCU \ ASPNETMVC - hopefully it will do!

Any ideas?      you can    git rev-parse -verify HEAD    (after :)     This is a pipeline command, and its behavior vs. "  git diff " There is very little possibility to change   I find it more pronounced  rev-parse -verify  means "is this a valid object name?"    This is your  show-ref .  You ask "Is there anything in this safe / head in the safe?"  I ask, "what current  head  exists?"   In practice, both of these are fair tests, because once you have a branch, so to achieve the  HEAD , some mock values will indicate manually lack of editing It is very diffic...
