How to run application in qt as administrator?

How to run application in Qt as administrator? After build, instead of right click and run as administrator everytime. Once the build is over, if we just double click the app.exe. It should run as administrator automatically...

For Windows you embed an application manifest specifying the required requestedExecutionLevel. You will not avoid the UAC prompt if that is what you are hoping for. If you application needs to display anything in the GUI I think you also have to sign it.

For Mac. Don't know.

How to do the same using Mingw?

[ChrisW67]

The same way. You write your manifest XML file, include the relevant entry in your application's RC file, and rebuild your application.

Your PRO file:

...
RC_FILE = coolapp.rc
...

...
RC_FILE = coolapp.rc
...

To copy to clipboard, switch view to plain text mode 

Your coolapp.rc file:

#include <windows.h>
 
ID_ICON    ICON    DISCARDABLE    "coolapp_desktop.ico"
CREATEPROCESS_MANIFEST_RESOURCE_ID RT_MANIFEST "coolapp.exe.manifest"

#include <windows.h>

ID_ICON    ICON    DISCARDABLE    "coolapp_desktop.ico"
CREATEPROCESS_MANIFEST_RESOURCE_ID RT_MANIFEST "coolapp.exe.manifest"

To copy to clipboard, switch view to plain text mode 

Your manifest file (coolapp.exe.manifest):

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
  <assemblyIdentity version="2.0.0.0" processorArchitecture="X86"
  name="gokulnathvc.coolapp" type="win32" />

  <dependency />
  <!-- Identify the application security requirements. -->
  <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
    <security>
      <requestedPrivileges>
        <requestedExecutionLevel
          level="asInvoker"
          uiAccess="false"/>
        </requestedPrivileges>
       </security>
   </trustInfo>
   <!-- padding to four-byte multiple file size including the byte order mark -->
  <!-- padding 123 -->
</assembly>

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
  <assemblyIdentity version="2.0.0.0" processorArchitecture="X86"

You will need to adapt that manifest to set the requested execution level. (You can probably ignore the comment about padding, it works around a bug with early compilers the specifics of which I cannot quite remember)

Shall we do that in project settings. instead of doing that out side.. possibility of doing that as post build.

Was there a question in there somewhere?
