control1.SetBou nds(x,y,... needs to have the positions of the scrollbars thumbs subtracted from x and y

Given a control1 on a UserControl:

After much experimentation I find that the x and y values given to
control1.SetBou nds(x,y,...
needs to have the positions of the scrollbars thumbs subtracted from them.

That is, to put the control in the top right corner of the usercontrol (i.e,
0,0) use:
control1.SetBou nds(-hScrollShift, -vScrollShift, ...

I can't find anything in the doc to explain this.

Also it seems that setting Top or Left directly does not require the
addition.

Can anyone verify this or correct me.

Especially nice would be direction to some documentation.
Thanks in advance

I have a rudimentary gui with a class that extends JPanel, which sets its content to a jpg image using: if (im != null) { g.drawImage(im,0,0,null); } in the paint() method. However, when I create a JScrollPane that uses this JPanel extension as its scrollable client, and call a validate, the scrollbars get visuall overwritten with the jpg image. Has anyone encountered this error before and knows how to fix it?

Hi all, I've got an application that I'm writing that autogenerates python code which I then execute with exec(). I know that this is not the best way to run things, and I'm not 100% sure as to what I really should do. I've had a look through Programming Python and the Python Cookbook, which have given me ideas, but nothing has gelled yet, so I thought I'd put the question to the community. But first, let me be a little more detailed...

I have a usercontrol on which I have, say, five controls. I want a context menu to popup when the mouse is clicked anywhere on the userconttrol. The same context menu. What I've done in the past is to put code in each control's mouseup event. Is that the way to go or is there a better way?

What is the best way to ensure the location of a form before it becomes visible? Letting is become visible and then...

Hello guys. I just tried out using the setBounds method after looking at it in the Java API under JButton (though any other component should have it) and so anyways I tried it out in a simple little program. But no matter how much I change the parameters the button never changes. Why is this?

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
