But i don't want to use signal and slots @BasileStarynkevitch I just want to switch between two window with data using push button. If i click on push button then it can take all checked data and go to the next window.

Your code is poorly formatted and is not an Minimal, Complete, and Verifiable example. It should have amainfunction to become one

Please edit your question to improve it a lot: format properly your code, extend it to make it some Minimal, Complete, and Verifiable example (with amain), and explain in details (with several paragraphs) why you don't want to use Qt signals and slots.

the initial question was:
How to go on next page using push button in qt c++ without use of Qt signals and slots?
This is practically impossible, and certainly inadvisable, since Qt signals and slots is the basic foundational mechanism of Qt, used everywhere inside it.
Be sure to take more time to understand Qt signals and slots and study several Qt tutorials and examples. Consider also studying the source code of Qt5 itself (since it is free software). And you can also find many Qt open source applications (e.g. on github, gitlab, inside a Linux distribution, etc...) which should be inspirational (if you don't have time, you could pay some Qt consulting corporation to do your work).
My recommendation is to create some Qt QPushButton (perhaps subclassing that) and connect its clicked signal to your appropriate slot somewhere. The calculator example should be inspirational. You probably should subclass QTableWidget to add a new slot, and use that for your m_pTableWidget or at least declare your MainWindow::on_pushButton_clicked as a public slot (and of course connect it appropriately).
If you don't want to use Qt signals and slots, you should give up using Qt and choose some other widget toolkit. They all have some notification machinery (at least based on callbacks), and IMHO the design of Qt signals and slots is quite good (and sometimes better than what other toolkits provide).
Read also How to debug small programs
It seems that you don't understand the design principles of Qt (i.e. the fact that Qt signals and slots are central to Qt, so you should use them extensively). So I recommend taking a few days to study carefully the documentation of Qt (it is well written, but extensive; start with Getting Started Programming with Qt Widgets) and the source code of existing examples (including Qt itself); throw your current code to the trash bin; then rewrite it with an iterative and incremental development approach : code a few dozen lines at once, compile them (with all warnings and debug info, so g++ -Wall -Wextra -g with GCC), improve them to get no warnings, test your incomplete program - using the GDB debugger -, make sure it works as you want it to, and add one more small feature (perhaps just a single new widget) and repeat. Of course, use a version control system (I recommend git) and commit your code frequently (at least, at every loop of your iterative and incremental development approach).
NB. you have changed your question entirely (at first, you refused to use Qt signals and slots; now you accept to use them). Of course, you need to read carefully the documentation of every used widget (including the superclasses), notably of QTableWidget and of QTableView. And you need to define what a "page" is (and what going to the next page means), since QTableWidget don't know about them.
take time (several days or a few weeks) to read the documentation of Qt.

Without some Minimal, Complete, and Verifiable example your question is unclear. You need to define a Qt slot doing that appropriate operation. Read more about Qt signals and slots

But i don't want to use signal and slots @BasileStarynkevitch I just want to switch between two window with data using push button. If i click on push button then it can take all checked data and go to the next window.
