When you say "WS" what specifically do you mean? I've run the Qt IDE and 
programs compiled for Qt on Raspbian on occasion, and apart from the 
usual problems of element spacing being slightly adrift etc. have had no 
significant issues that wouldn't be expected on a PC... noting obviously 
the current problems that somebody has with VNC, which I don't think is 
really a Raspbian issue.


Something like two or maybe three years ago I tried to graft KDE onto 
Raspbian and it wasn't entirely successful, but there were other factors 
involved (e.g. a 4K screen which was pushing the graphics capability at 
the time). Most of the time we run a hybrid of the Raspbian kernel and 
Debian apps etc., to a variety of 1080p and 4K screens.

Under Ubuntu 18.04 LTS with Lazarus 1.8.2+dfsg-3 and FPC 3-04 the AltGr 
keystroke combinations work fine. Same VNC-Server and VNC-Viewer.

[Lazarus] Qt WS on Raspberry pi 3

[Giuliano Colla via Lazarus]

Hi all,

before starting from scratch, and falling in the same pitfalls someone 
else has already learned how to avoid, is there anyone who's already 
successfully managed to use the Qt WS on Rasbian for a Rapberry PI 3?


Thanks in advance for any hint.

Re: [Lazarus] Cannot enter '^' in Lazarus trunk build macos/cocoa/x86_64

[Michael Ring via Lazarus]

I guess you will have to install the german layout as this deadkey stuff 
is layout specific.


Fun fact is that you also cannot enter ^ with the Keyboard overview of 
MacOS, when I switch to US keyboard all is fine for me.


fyi, the '^' key is left of the '1' key on a german keyboard on Macbook Pro

Do you know, if it's required to have German layout to be installed in 
the system.
IIRC (away from mac right now), "^" is entered by pressing Shift+6 on 
Mac (ansi keyboard with US keys layout) ...and it works.


What I'm thinking is that you're trying to enter the character in SynEdit.
and it might be that Cocoa doesn't report a certain key combinations 
properly.


I presume you didn't have this issue in Carbon, thus it's neither 
SynEdit bug nor macOS specific behavior, but rather LCLCocoa issue.


That's why I need to know keys combination in order to track the 
problem on my end.

Re: [Lazarus] Lazarus still not usable with VNC under Raspbian

[Joe via Lazarus]

The same or a similar problem I see using Lazarus 1.6 under Ubuntu 16.04 
LTS, running X11 VNC Server 0.9.13-1.2build1.


I connected from a windows 10 computer with VNCViewer 6.1.0 from RealVNC 
to the Ubuntu machine, opened Lazarus and tried to insert a '[' char 
with AltGr+8 in the Lazarus code editor window. Alternately, no char or 
wrong chars were inserted. The same happened, when I tried to insert 
other AltGr combinations like { and ]. Country and keyboards settings on 
both machines: Germany.


Added a note to case 30544 in the Lazarus Bug Tracker.

Same here. That's why I often use the IDE directive.

I do not want to kill the warning for all files, only those I have reviewed.

[Lazarus] Clipboard method needed to clear cache

[AlexeyT via Lazarus]

LCL uses clipboard cache to support all clp formats on all OS, even if 
OS don't support some.


In *CudaLister plugin for Total Commander* [based on CudaText parts], I 
need method to clear this cache. Clipboard.Clear is not ok [i need 
contents of OS clp]. Method needed to solve this issue:


https://github.com/Alexey-T/CudaLister/issues/27 (english text also). I 
will call it before reading Clipboard.AsText.

Hello Michael,

Is there a documentation link to explain all new features?
I'm gonna start a new web project and I would like to use them.


I will see if I can put something in the wiki.



What about the design packages for Lazarus?
The wizards continue creating Web Module based applications.


A good point. 
I had not thought of this. I will put it on my todo list.

You can:
a) add a dummy statement: if Value='' then ;
b) add an IDE directive: right click on this message in the Lazarus
Messages window, Hide message by inserting IDE directive

It should be "off". I fixed that in trunk.
