Qt application increases memory

[chiragbprajapati]

Hi,

I have developed Qt application using qml and cpp in which i created too many windows which are all initially created at start up time, i just set visible true/false whenever i required/remove it. but when i change the visibility to true/false for too many windows it continuous increasing the memory slowly. initially it was 69 Mb and after some time it reaches to 90 Mb almost. can any one help?

Take a look at loader. You can use it to only load views when you need them. I found it sped up one of my apps a little bit and decreased memory usage.

There could be many different reasons for an application to increase memory use over time. For example, there could be a simple memory leak in your app. You can try running the app in Valgrind's memcheck to see where the memory is allocated.
