Are there plans to merge some windows?

Like here (best solution):
https://cdn.portableapps.com/GeanyPortable.png

Because I think it is no more up to date.
I don't know any other Software that uses so many windows across the whole desktop. It would be more userfriendly to merge at least the main window with the code window. So that on top of the code window there are the buttons of the main window. Also the output window could be one tab of the search window.

Very often I use the search dialog.

It would be way more userfriendly if the search word (for example) can be double clicked and then is transferred automatically in a field at the bottom of the code window.

Like here:

I mean search result window more precisely.

Because I do not see at all and I Am using screen reader NVDA, it would be ideal, if so much of Lazarus GUI would be 100 % accessible. But I know, that it is very complex to retain screen readers accessibility, friendly look for sighted users and fast IDE responsiveness. For now, I would like to thank you, that you have allowed visually impaired users to use edit field inside source code wiev. Screen readers users are even notified about line number on focus. Sure, because it is not standard Windows Microsoft Edit control, it is impossible to use CTRL+SHIFT+arrow keys to assign some block of text with screen reader, but I know, that also commercial Delphi which uses his own controls not standard Windows controls from Microsoft have similar issue. The most difficulty question is to determine, what is more complex. Modify Lazarus component sources or customize NVDA screen reader for accessibility of non standard controls.

You can install the AnchorDockingDsgn package and have all windows integrated (except for forms which need an additional package).

About ctrl+shift+arrow key: Do you know any documentation on how to implement this. What API to call, to let the screen reader know?

Also for other modifications needed, any documentation?

Rainer, there's an add-on that's included with Lazarus that will "dock" all the windows to give a more "modern" Delphi UI vs the standard Delphi 7 UI.

g.

I seriously hope that this NEVER becomes a default setting for Lazarus.

Anyone who seriously develops software, specially desktop applications, is/should be using at least two (better 3 monitors). And the "many" different windows allow easily to spread those out to those various screens as needed. One screen has the source code and associated windows, the second one the debugging windows, and the third one has the actually tested application screen.

Something like this would be a major PITA with those stupid docked windows. That's only something that makes sense for someone who's tinkering along on a laptop or such...

It is not a fixed docking. You can undock any window and place them on other screens. Or dock only some and place them on another screen.

That is completely new for me that the amount of monitors is an indication of how professional someone can write good software.

For you that may makes sense.
But for me that seems like pretending who has the biggest car.

That sounds good for both use cases.

But how can I install/activate it.

I tried with apt-get install AnchorDockingDsgn
But that does not work.

It's a Lazarus package (lpk).

CEST Rainer Stratmann wrote

I found an instruction, but I got an error:

lazarus.pp(1,1) Fatal: Kann anchordockingdsgn nicht finden verwendet von Lazarus. Check if package AnchorDockingDsgn creates anchordockingdsgn.ppu, check nothing deletes this file and check that no two packages have access to the unit source..

Schwachfug. (Bollocks for the Anglophiles around here)

It's just a very efficient way to work, as you don't have two switch back and forth between hidden/overlapped windows. A two screen solution was even available back in the good old days of DOS, when you ran your application on color (xGA) screen and your debugging and source window(s) on an additional monchrome (Hercules/MDA) monitor. One of the reasons why the Borland IDEs where lightyears ahead of Microsoft and the other guys.

And this not only is an efficient way to program, but also for other, everyday work. A lot of my clients, once they have used a 2-screen setup would never go back to a single screen and dread when they have to work off a single screen laptop (or tablet) for example.

Have yet to see this work. I always ran into the problem that I needed to change the overall graphics driver setting to "full screen" a window over more than just the active monitor. Which is kind of pointless for most work with multi-screen setups. I will test this on this latest Lazarus version sometime later today on one of my secondary PCs.

But I still think that this should not be the default setting...

And for those with American English: B*S*

But I really dont see where to put 2nd, let alone a 3rd  50 inch screen. ;) ;) ;)

... not (unfortunately)

SCNR

I have only 2 eyes, so I'm going to find 3 screens a problem.

Martin.

Showoff! :P

Ralf ;-)

PS: Seriously, I rather buy 2 (or 3) smaller 24" or 27" monitors than one 50". Maximizing any window on such a big screen (even if it would support a pixel resolution that would be the same as 2-3 smaller screens) is still a HUGE downside, beside the mere cost...

Could we get back on-topic, please?

First, this is fpc-pascal list, not Lazarus list. Announcement of new release was OK, discussion about Lazarus IDE features doesn't belong here.

Second, discussion about two options already existing in parallel (docking and independent windows) might not have too much sense even on a Lazarus list, but that's just my personal view.

Third, discussion about the most appropriate number of monitors is completely off-topic unless this is something like alt.ergonomy group or whatever that would be called. Please, stop it (everybody).

Thanks

You did read my next line? "not"

You are preaching to the choir

I never maximize any of the IDE windows.
Typically I have 2 source editors, side by side, full height (which means I need another screen for the IDE main bar, and msg window).

But screens space belongs in the category: You don't miss what you don't know.
I remember hacking 68k asm on a 14 inch tube.... I was perfectly happy with then, with the space I had.

As you may have not seen while being busy with something else... I repeat it for you.

What did you do?

Packages / Install Packages
Select anchordockingdsgn on the right side and click "Install selection".
Then "Save and rebuild IDE".

Hi,

since I need glasses, it is already troublesome to read a single screen.

With strong glasses just one point on the screen is really sharp and when the glasses shift a little, you end up seeing only on one eye properly

Cheers,
Benito

Thanks, I decided to check out the branch 2.0.x rather than tag 2.0.0 and then 2.0.2 etc,
Seems like it would be easier to go forward if one is on the fixes branch, right?
Just svn update followed by:
make clean
make bigide

It took a little while today since I was on the tag earlier, so I checked out the fixes branch separately. But going forward I expect a svn update will run pretty quickly and then a normal make of bigide is straightforward too.

Thanks for having the repositories available so easily!

Yes.

Hello,
For the past 10 days, I've seen really strange speed problems at my end.

In 2 Ubuntu virtualbox VMs (16.04 and 18.04), my neural networks are running at half speed than usual. The host is a WIN 10 computer. Neural networks are both CPU and memory bound. Therefore, there is something affecting either CPU or memory.

Testing on Google Cloud, the speed is normal. This made me think that the speed problem was local to the testing environment. Just for peace of mind, I sent a string concatenation algorithm implemented in FPC to a friend to measure speed. To my shock, the same speed problem I was experiencing at my end is also happening at his end. This makes me believe that my problem isn't isolated.

Trying to find why things are slower at my end, I reverted my code to the code I had 4 months ago and also reverted the compiler to the same version I was using before (Stable 3.0.4). There was no luck.

Therefore, something really strange is going on:

- It's not a compilation problem. I moved binaries from an environment that doesn't have the speed problem to an environment that has the speed problem and I can verify the problem even with a binary built from a good machine.
- So far, it affects Ubuntu 16.04 and 18.04 (I haven't tested in other distros). WIN10 is good.
- A binary that works well on Google Cloud is slow with my own virtualbox VMs 16.04 and 18.04.
- It also affects at least 1 notebook with Ubuntu 16.04 installed as host OS.
- My CPU reports: cpu_meltdown spectre_v1 spectre_v2 spec_store_bypass l1tf
- String concatenation is also affected making me to suspect about something wrong at malloc/libc.
- Numerical results from neural networks are correct. So far, it's a speed problem.

My question to you is: if anyone from you suspects that something might be wrong at OS level affecting either your CPU speed or malloc/libc/memory at your end that might be related to what I'm seeing here, please share. I have algorithms running at my end from a quarter to half of the original speed.

Hello,

It's better not to reply to an existing mail with a completely new topic, cause now your mail is burrowed deep in the "Lazarus Release 2.0.2" thread.
Better write directly to the list without replying.

You can try disabling spectre protections in your Linux installs: https://access.redhat.com/articles/3311301

Thank you for your help Jonas. It was a good guess. Unfortunately, adding "spectre_v2=off nopti pti=off" didn't help.

True, there probably is no direct correlation between multiple monitors and professional developers.....

But G*D damn, having multiple monitors are super useful when it comes to desktop management. I started off with 2 monitors and 3 virtual desktops (same apps always on same virtual desktops), and for the last 5 years have been working on three monitors (hardly ever use virtual desktops these days). 2 monitors were already a massive upgrade and 3 seems to be the sweet spot for me (desk space and peripheral vision).

My setup:

21" vertical on the left (1080x1920)
27" landscape in the middle (2560x1440)
21" vertical on the right (1080x1920)

All aligned on the top edge of the monitors.

e-mail client, web browser, console windows, help files (eg: pdfs, chm or inf) are normally on the outer monitors, and development tools are always in the middle. I absolutely love this setup!

Graeme

Habe jetzt das ganz neue Debian 10 - mit apt-get install lazarus (2.0.0) - auf einem Rechner und es so wie oben beschrieben probiert.

Der Complier sagt: kann anchordockpgk nicht finden
