QUESTION
I am trying to retrieve a value from window.sessionStorage in my BLazor application. I have been able to successfully SET the value. It's when I go to retreive it that it simply stops ... no error or anything ... it just hits the function and stops.
I have my code set up in a "Code-Behind" structure so my .razor page is inheriting from a BASE class. In that base class is where I am storing all the logic.
This is the RAZOR page ...

I am going to open the photo viewer using .net core and this is my code
...ANSWER
Answered 2020-Aug-18 at 05:15After researching this I noticed folks using rundll32.exe to execute an export from PhotoViewer.dll to display a picture using Microsoft Photo Viewer application. So I think that's what OP was trying to do, they just forgot to use the rundll32.exe application.
So I thought I'd take a crack at this and not use the rundll32.exe and just call the export directly. I debugged it with x86dbg and saw that it's passing in 4 parameters: pointer, pointer, pointer (to wchar_t*), int. I don't know what the parameters do, so I just set them to NULL and made sure to pass in the path to the picture as the 3rd and it seems to work.
So this will do what you want it to do. I know that hard-coding system paths is bad practice, but maybe someone who has more time can make this more dynamic.

QUESTION
I'm having an issue with max-width/max-height inside of media queries. Basically what's happening is I have an image gallery that uses jQuery to display a modal window. This modal window consists of the modal, a content box, and an image viewer which has some buttons inside for navigation thru images). I have the max-width/max-height set in vw and vh in css but the exit button gets cut off on a mobile device.
Current CSS:
...ANSWER
Answered 2017-Mar-30 at 00:34At least in the fiddle you posted it works:
The images' original sizes there are only 200x133px or vice versa. With max-width/ max-height values they will never get larger than their original size.
Only if the screen/viewport becomes less than 400px wide, the max-width: 50% will have an effect (for landscape mode images, that is - portrait even less: narrower than 266px).
QUESTION
I have a png that is read into my python program as a QGraphicsPixmapItem. This QGraphicsPixmapItem is then added to a QGraphicsScene for display. Within the display, users can zoom in and pan through the image. This works as intended.
My question is this: How can I determine what PNG pixel values are at the corners of the QGraphicsScene after being zoomed and panned?
Is there a built-in PyQt method for this?

QUESTION
In my main window I set a variable self.print_this. I then call another class PhotoViewer and then in that class I call a function from my main window. In that function I try to print the self.print_this but I get the following error: AttributeError: PhotoViewer object has no attribute print_this
How do I access the self of the window class or avoid sending the self of PhotoViewer to the printfromwindow function?
ANSWER
Answered 2019-Sep-18 at 01:45Untested, but perhaps something like this. Note that in your code, you're calling methods of the Window and PhotoViewer classes but not constructing an instance of those classes.
You need to instantiate and retain those instances within their parent/child class instances, if you want to be able to reference their methods/properties.
As noted in my comment above,
Window.printfromwindow(self)should not have theselfargument (and should instead refer to.printfromwindow().
In the Window constructor, I assign self.viewer an instance of the PhotoViewer class and pass self (which is a Window instance) as the parent argument to its constructor.
Then, in PhotoViewer class constructor, we do self.window = parent which should allow you to call self.window.printfromwindow():

I'm trying to link two qgraphicsview objects so that when one window zooms in the other qgraphicsview zooms as well. I'm trying to accomplish this by calling the test function when one window is going to zoom. I then try to call self.scale(factor,factor) in the other qgraphicsview object. I get an error :AttributeError: 'PhotoViewer' object has no attribute 'viewer'. How do I get I'm trying to call the class ui self.viewer but judging from the error I'm still in the Photoviewer object. How do I call the other windows self.scale from when one window is zoomed in? Thanks in advance.

QUESTION
In my program I can select a button that sets self.rectmode=1. Once that variable is set to 1 it draws rectangles using mouse events on the qgraphicsview. After pressing a button to set self.rectmode=0 the program continues to draw rectangles using the mouse events. Am I missing some line to end the rectangle drawing event. My code is below thanks in advance:
...ANSWER
Answered 2019-Aug-27 at 08:28In your code rectmode is always 1, I think that is what's causing the problem, here is a working example, I also removed the variable changeRubberBand because the same can be achieved with only the variable rectMode:
QUESTION
I am trying to make a gui where the user can move the image around in drag mode and switch to draw mode to draw on an image in a qgraphicsview. I have the code from examples I have found but I can't figure out how to toggle between the two mouse events. I'm also struggling with how to link the two qgraphicsview objects so that drag and zoom events are shared between the two. My code is below if anything doesnt make any sense dont hesitate to ask. Thanks in advance.
...ANSWER
Answered 2019-Aug-26 at 22:01There's a typo in def drawmode, which calls "toggleDrawMode" instead of "toggleDragMode". Besides that, it's better to avoid painting on a view (unless you really need to and know what you're doing) or directly on an image while moving the mouse, and a better approach may be to add a QGraphicsPathItem on mouse press and actually paint on the image after releasing the mouse button:
