Lazarus Release Candidate 5 of 1.8 (includes RC1 fpc 3.0.4)

[michaelthuma]

Thank you. Works great so far here. The only thing left is an 'issue' while debugging I don't really care about.

Given a simple OnClick event handler the following code presents a not updated value in case of c

var
a,b,c : integer
begin
  a := 1;
  b := 2;
  c := a + b;
end;

Debugger shows the initial value even if the cursor is positioned on the line end;

Works if the line c = a + b; is followed by any other statement.

That's little confusing but does not matter in the end and very likely nothing specific to this release.

The real disappointment is the missing ladybug  on the Run button. I liked it so much. On the other hand many icons became very professional which make Lazarus look great.

Did you compile with -O1 or -O-

With -O1 the compiler recognizes that c is not used afterwards, and may skip storing it to memory (It will hold it in a register instead, but the compiler tells the debugger, that it was in memory...)

Playing around with an old project of mine ..

Tested under Windows 7

- no mainfest
- enabled LCL-scaling (Hi-DPI)

125 %

[PeterX]

150 %

[PeterX]

I must check next what happens under Windows 10 ..

[PeterX]

Under Win 10 - 100 %

125 %

[PeterX]

Under Win 10 - 150 %

[PeterX]

Okay, now I know why I never complained ... I never tested higher % under Windows 7. And 150% under Windows 10 seems to be acceptable.

The component TRadioGroup does not paint well under Windows 7
when zooming 150 % .

Did you follow the rules für DPI-aware applications? http://wiki.lazarus.freepascal.org/High_DPI#High_DPI_in_Lazarus_1.8_and_above

I'll have a look at that, thanks.

But this may have nothing to with ... :

It paints okay (look at the Radio buttons ..) under Windows 10 when zooming 150 % .

I'll follow the description in Your link and then report here soon !

I doubt that. Before answering I had just tested this with an LCL-scaled project with manifest and Form.Scaled := true - no problem.

You should write a little demo and upload it here.

[PeterX]

Demo follows.

In the first step I simply copied the TRadioGroup
out of my project by Windows Clipboard.

Rows are too narrow now ..

What is the left image, and what is the right image?

[PeterX]

Left is design time, right is EXE running.
