[Lazarus] HI-DPI Strangeness

[Donald Ziesig via Lazarus]

Hi All!

I have noticed strange behavior with Lazarus 1.7 in the HI-DPI mode.  
This took some trial and error to find since the connections are not at 
all obvious.  I am using Linux Mint 18 and have the same problem with 
both MATE and XFCE desktop managers.


When I log out/shutdown/restart and return to Lazarus, the Object 
Inspector DPI settings are all at 96 (even though they were all at 144 
when I shutdown Lazarus).  The IDE Icons are all tiny (almost 
invisible), the source editor windows all had a very small font size, 
the Form designers were all hosed, and the programs built with Lazarus 
(after the restart) all appear to be compiled with 96 DPI.  I tried 
rebuilding the IDE, but that had no impact.  The DPI remained at 96 as 
did everything else.


Here is the weird part.

After restarting, I opened a terminal and entered the command "xdpyinfo 
| grep dots" to see how it was set.  The response was 144x144.   
Apparently the window manager(s) got the message ;-) even if Lazarus did 
not.  Note that I did NOT enter any other commands except for the xdpyinfo.


BUT

When I restarted Lazarus the IDE Icons, the Form Designers and the 
source editor fonts were were correctly sized, and the programs built 
with Lazarus were correctly sized for 144dpi.


I have appropriate xrandr and xdpyinfo commands in .bash_profile and 
.bash_login (redundancy can't hurt :-D).  They don't seem to help.  I 
restarted again, opened a terminal (which showed my debug "echo"s so the 
two files were executed) and did nothing else.  I then CLOSED the 
terminal and started Lazarus.  It came up in 144dpi mode!!!.


I can not tell where the interaction between Lazarus and the window 
managers fails, and I have a work-around (open terminal before starting 
Lazarus) so the problem is not serious, but it remains an annoyance.


=

One more minor issue.  The Main Menu editor still has issues with the 
height of fonts in HI-DPI mode, as in:


Again this is not serious, just annoying.


Thanks,

Don Ziesig

To me it looks like Carbon applications are scaled automatically by the
OS. Something similar to what also Windows uses if you switch High-DPI
awarness off.

That means the regardless of your screen (retina, non-retina) the DPI is
always 96. So there shouldn't be any LCL-scaling involved.


hm...just tested Qt4 and Qt5 on MacOSX.
Qt4 - MacOSX 10.8.6 32 bit (qt4 library uses carbon for it's widgets)
Qt5 - MacOSX 10.11 64 bit (qt5 library uses cocoa for it's widgets).

When Application.Scaled = False fonts of some controls are resized to 
smaller fonts (DesignTimePPI on both macs says 72 ) - so my question are 
here:
1. is 96dpi hardcoded somewhere, so it underscales some fonts in case 
when dpi is 72 - even with Application.Scaled := False. ?


2. Some forms eg. About lazarus is shown too small, seem that it's 
scaled to the smaller size because of dpi 72. (ide have 
application.scaled := True by default), also Find Dialog is reduced but 
all child controls of FindDialog haven't scaled fonts ,so dialog isn't 
sized well.


Note that both cases were fine before HiDPI changes, also please keep in 
mind that Lazarus OSX isn't carbon or cocoa only, but qt4 and qt5 too.


On linux and windows everything works pretty nice (Application.Scaled := 
true and Application.Scaled := false) with qt4 and qt5 widgetsets.


My app is designed on linux (96 dpi) and then just rebuilded on mac (if 
that matters), also Mac 10.8.6 is iMac with resolution 1440x900 72dpi, 
Mac 10.11 have resolution 1920x1200 72dpi (this one is running inside 
vmware).


Any hints ?

Re: [Lazarus] Colorconversion in htmlreport

That makes no sense to me.
#D8FFF4 looks like HTML color coding, so calling ColorToHTML on that
makes no sense (or the name of that makes no sense).

Here's a ColorToHtml function from the SynExportHtml unit that works
correctly (at least in my limited tests):

function ColorToHTML(AColor: TColor): string;
var
  RGBColor: TColorRef;
  RGBValue: byte;
const
  Digits: array[0..15] of char = '0123456789ABCDEF';
begin
  Result := '';
  case AColor of
clRed: Result := 'red';
clGreen:   Result := 'green';
clBlue:Result := 'blue';
clPurple:  Result := 'purple';
clYellow:  Result := 'yellow';
clBlack:   Result := 'black';
clWhite:   Result := 'white';
clGray:Result := 'gray';
clMaroon:  Result := 'maroon';
clFuchsia: Result := 'fuchsia';
clLime:Result := 'lime';
clNavy:Result := 'navy';
clAqua:Result := 'aqua';
clTeal:Result := 'teal';
clSilver:  Result := 'silver';
  end;
  if (Result <> '') then
Exit;
  RGBColor := ColorToRGB(AColor);
  Result := '#00';
 {}
  RGBValue := GetRValue(RGBColor);
  if RGBValue > 0 then begin
Result[2] := Digits[RGBValue shr  4];
Result[3] := Digits[RGBValue and 15];
  end;
 {}
  RGBValue := GetGValue(RGBColor);
  if RGBValue > 0 then begin
Result[4] := Digits[RGBValue shr  4];
Result[5] := Digits[RGBValue and 15];
  end;
 {}
  RGBValue := GetBValue(RGBColor);
  if RGBValue > 0 then begin
Result[6] := Digits[RGBValue shr  4];
Result[7] := Digits[RGBValue and 15];
  end;
end;

Note that the represetation of TColor and HTML color (if you both
write them out as hex) is not in the same order.

[Lazarus] Colorconversion in htmlreport

[frans via Lazarus]

Hi.
I use Lazarus 1.6.2 with FPC 3.0.0 on Windows 10. I use htmlreport to 
create webpages.
My problem is the use of colorcodes. I want to use the color #D8FFF4. 
But the function Color2HTML translate that code to $00D8FFF4# and that 
gives a totally different color.
I've searched the internet for a converter but found nothing. Therefor I 
have 2 questions:

1. What does the colorcode $# mean? It's not ?RGB.
2. What code should I use to get the colorresult I want?

[Lazarus] Projectgroups in Sourceeditor Toolbar

[Andreas Frieß via Lazarus]

Is there an way to bring the menuentries of the projectgroups in the 
toolbar of the sourceeditor ?


If i go into the 'Toolbar Configuration', i didn't find the entries like 
'Open Projectgroup', in the mainmenu it is shown, but not in the editor.


Lazarus 1.7 rUnversioned directory FPC 3.1.1 i386-win32-win32/win64 
(Lazarus trunk/ FPC trunk)
