Author Topic: [SOLVED] Show Center of monitor screen (Read 60,532 times)

Solved (https://github.com/lacymorrow/crossover/releases/tag/v3.1.5)
Original text:

Editing a wallpaper photo, I need this little dot to be situated at the very center of the finished photo = the center of the screen. So I fumble around with my calculator and papers, but it would be so much faster if I could only press a hotkey and up comes some crossmark of a kind, illuminating the exact place at once. Then I could maybe hit the same hotkey again, and the crossmark disappears. Or how it should be done.

It could very well look just like Skrommel's MouseMark, or whatever 'you', dear coder, will like it to.

Any takers?

see if this helps you: ShowScreenCenter.

you can press Capslock to show/hide a tooltip at the center of the screen. btw, i've only tested on a single monitor system with the taskbar at the bottom.

[user]lanux128[/user] wonders if anyone tried this script.. $:-\$

Curt · « **Reply #3 on:** June 16, 2009, 12:40 PM »

- inside my little head I answered and thanked you long ago, but now I realize that I wrote nothing! Sorry!!

Yes, of course I've tried it, and it works fine.

There are some behaviours that I don't fully understand, when I have a window of a kind open, but for the time being I have simply minimized all windows before I press the hotkey and only then maximize the IrfanView window, to see where the center is. Within this frame, ShowScreenCenter works just perfect.

Thanks, lanux

thanks for the feedback, Curt. i was wondering whether this script suited your purpose and i'm glad that your response has indicated it is so.

btw, what was the behaviour that you mentioned? if you want, the script can be modified to work only if certain apps (such as IrfanView) are active.

Curt · « **Reply #5 on:** June 16, 2009, 01:32 PM »

- thanks for the extra offer, but I am changing default apps much too often ;-)

Curt · « **Reply #6 on:** April 20, 2021, 03:00 PM »

lanux128 has not posted since November 2019...

Any takers to my problem?

The app is not doing its job properly on my 1920x1080: The cross comes up half a centimer off center! -even with no apps open.

I don't have the neccessary notes to go back and investigate when this began, I never imagined it could be needed.

Hi Curt, I'm in with ScreenMark!

Do you have the exact same requirement? i.e. show a mark @ the very center of your screen? Anything else?

(Do feel free to expand for v0.1.0)

Without knowing the full details, my guess is that it has to do with the taskbar always being displayed by default.

I recently encountered a similar issue where an app I use (DisplayFusion) wasn't properly centering windows on my monitor and I found that by setting my taskbar to hide then it would center them properly.

Hi Curt, I'm in with ScreenMark!

Hello again! In the process of creating the graphical interface for ScreenMark now

Currently adding mark on:

- Screen center.
- Working area center.
- Active window center.

With the options:

- Display mark on all screens (for multi-monitor setups).
- Enable Hotkeys on ALT + SHIFT + M.
- Rounding by floor or ceiling.
- Move cursor to latest mark.

This can do the job for first version.

More features can surely be added if you (or any other fellow user) require it later.

Feel free to comment if you want different hotkeys, et cetera... First version is the most-malleable stage

Cheers!

Yes, Vic, same procedure. The very center.

But Deozaan made me realize that the taskbar can make a difference? However, I have never had the need for the precise vertical spot, merely the horizontal (width) one. So I am GUESSING that the taskbar that Deozaan is mentioning, not is the problem; I was only talking about the spot being too far to the right. I have not even checked if the displayed spot is too high up or what. Edited: I have Taskbar > AutoHide

Super! The math's straightforward & the WinAPI calls are pretty documented

Fast-tracking this app as the very first of our "Public Domain REIMPLEMENTATION" service

FYI the taskbar is not part of the desktop client area. Normal apps center on desktop, so their centering is correct.
You can write code to get around that issue for people who use a ruler to notice that at all

I think you are correct that my guess was unrelated to your issue after all.

My problem was that I was trying to use OBS to capture a 1920x1080 portion in the center of my 2560x1400 monitor. So I used DisplayFusion and set up a hotkey to resize the current window to 1920x1080 and place it in the center of the screen. Where the window ended up and where OBS recorded on my monitor were not aligned (vertically, as Curt correctly surmised). I found that by setting my taskbar to auto-hide, DisplayFusion began placing the window in the same location that OBS was recording.

[attachment 3 not found]It would be interesting to know if any of you guys have tried the (~~attached~~) original file from lanux128 ? It was fine on Windows Vista - so I am wondering if the problem might be my setup. I mean, how can (A_ScreenWidth/2), (A_ScreenHeight/2) give anything but the center? Why is there a problem in the first place?

Still just a guess and a fact; if author really has used your formula there would be another problem, "Screen" is a dimensional sum of all connected displays :-] (having 2 displays of same size the center would be "one half on left and one half on right display")
Luckily there are Api ways to determine position and size of taskbar, aslong original taskbar is used. If custom taskbar was used, last chance would be to recognize dimension of current active display to center things like you want to have it.

Hi guys! I'm "clipping" some functionality to publish this baby today. Core works in a straightforward way. The bells & whistles can be added in a further version (hey! this is the very first v0.1.0 release after all, there's room to expand

)

Cheers!

ScreenMark v0.1.0 released

It should be good enough for your use-case: Launch program, put target on foreground, press CTLR+ALT+M to mark.

This is traditional Winapi/GDI+ painting (so the mark is "sticky" until stopped).

We can try other ways to mark such as full-screen invisible click-though form Window & hooks if you wish

I'm open to adding improvements with further versions

i.e. Move cursor to mark / more control on mark features-/ other.

Cheers!

I have not yet tested further than opening, click hotkeys, closing, repeating a couple of times - and wondering What blue pen?

To me it is well working, Victor.

Would you care to add Start hidden / minimized to systray / notification area, please?

Sure thing. It comes with ScreenMark v0.2.0

Curt · « **Reply #23 on:** May 04, 2021, 12:41 AM »

Only now do I understand the original problem:

The blue plus in the picture is from the new "publicdomain" app, and the black&white 'plus' is from the old app from lanux128. Notice how the upper left corner of the b/w 'plus' -sign is in that exact spot the center of its plus-sign should be. So, the "ShowScreenCenter" program is accurate, as expected, but how to show the result, was wrongly formulated.

GirkovArpa · « **Reply #24 on:** May 05, 2021, 09:21 PM »

Here's an application I made a while back that looks like exactly what you need, plus lots of customization options.
