This article mainly introduces "how NSIS uses the installation interface made by Qt to make the installation package interaction". In the daily operation, it is believed that many people have doubts about how NSIS uses the installation interface made by Qt to make the installation package interaction. The editor consulted all kinds of materials and sorted out simple and useful operation methods. I hope it will be helpful to answer the question of "how NSIS uses the installation interface made by Qt to make the installation package interaction"! Next, please follow the editor to study!

Pay attention

   Qt is used to make the interface, the logic can be done first, but the logic of the button in the NSIS plug-in source code will be ui. Call, so the logic will also need to be migrated.

Introduction to the layout of plug-in project

The whole project of    adopts the form of plug-in   

Entry to the Qt program

   is actually similar to the dll call, putting the Qt call into the NSIS plug-in (author: msvc2017x32 version):      

Interaction between Qt programs and NSIS: Qt calls NSIS

   needs to associate functions in the plug-in (nsis plug-in code) in Nsis.    $0room9 and $R0~$R9 are built-in variables in NSIS and are used without declaration.    $0 is a callback function that temporarily stores the address:

Interaction between Qt programs and NSIS: NSIS sets Qt

NSISAPI function in the    plug-in to set the installation path to Qt:      

Interaction between Qt programs and NSIS: NSIS gets the installation path of Qt settings

Interaction between Qt programs and NSIS: NSIS executes different functions through Qt parameters

   sees the execution of the event    in the code in the Qt section

   finds the predefined event code in the plug-in code       sees the keyword       in the NSIS script (add: starting with $there are also some built-in variables or constants such as path or handle, such as $HWNDPARENT, $PROGRAMFILES, $INSTDIR, $EXEDIR, $WINDIR, etc.). ).

At this point, the study on "how NSIS uses the installation interface made by Qt to make the installation package interaction" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
