![]() You shouldn't create SecondWindow() in resizeEvent because when you resize main window then resizeEvent creates again and again SecondWindow() and Python removes old second window (assigned to cond_window) - and there is short time when old window is already removed and new window still doesn't exist - and you see it as flickering. cond_window = SecondWindow(self.width, self.height) # dimensions of main window passed to second window # dimensions widget applied to second windowĭimensions_win = Dimensions(width, height) I was able to get this to work but my problem is the second window flickering every time the data is updated when resizing the main window and I'm struggling with getting it to stop.įrom PyQt5.QtWidgets import QApplication, QMainWindow, QLabel, QWidget, QHBoxLayoutĭef _init_(self, width, height, parent=None): While it’s not for everyone, if you’re a serious shotshell reloader looking to treat yourself to the very best, you’ll love MEC’s Super-Sizer.I am trying to figure out how to pass event data such as size of the main window to secondary windows. For parents of young children curious about reloading, the Super-Sizer can also be a fun way to introduce the next generation to the hobby without exposing them to powder, primers or other more hazardous components. With no indexing, power sources or complex sequences of operations to monitor and fiddle with, you can focus on what you’re doing– Resizing hulls. The entire system is made up of just a few components. This not only dramatically reduces the amount of pressure (not to mention friction) needed to complete the operation, but it completely eliminates the possibility of hull binding, even with problematic high-brass hulls.Īnother great feature of the Super-Sizer’s design is it’s simplicity. This eight-finger die works to easily and accurately squeeze hulls back to factory specs horizontally, rather than the more common vertical method employed with ring-type sizers. Where the Super-Sizer really shines though, is the sizing collet. The rigid base has a large footprint that fastens securely to just about any surface, while the operating handle provides an excellent degree of leverage to help simplify an otherwise challenging task. Aside from build quality, the Super-Sizer also benefits from the engineering skills of the company that designed the world’s most popular shotshell reloading press. The Super-Sizer is one of the most rugged reloading tools you’re ever likely to encounter, with every part precision-machined to exacting tolerances, and built to withstand decades of heavy use. So what does the Super-Sizer bring to the table? The first thing you’re likely to notice about it is that like all MEC products, it’s made of metal– Steel, to be specific. By resizing our hulls, we can effectively squeeze the base back down to the original factory specs, and return it to service. ![]() ![]() Although the increase in diameter is very small, a change of even a couple thousandths of an inch can render a hull impossible to chamber. Whenever a shotshell is discharged, the explosive forces of the rapidly expanding gasses cause the hull’s metal base to stretch, and expand. If you’re new to reloading shotshells, you may be wondering why we resize hulls at all. If you just read the last few sentences while thinking “Amen, brother”, you’re not alone– For these reasons (and a few more) MEC took it upon themselves to develop a simple, yet innovative solution in the form of the Super-Sizer. Likewise if you’re the owner of one of the half dozen shotshell presses that just doesn’t include a sizing die, you’re no doubt equally well acquainted with the misery that is manual sizing using hand tools. ![]() Binding hulls can quickly bring an otherwise productive reloading session to a screeching halt, as the reloader is now forced to disassemble the sizing station, and extract the jammed hull. Spend any kind of time reloading high-brass shotgun shells using a ring-style resizing die, and you’re bound to stumble upon the all-too-common, and much-lamented issue of binding.
