I have no problem with you just with the broken feature. ;-)




Please open "dblookupcombobox.inc" (in (lazarus)/lcl/include), find the 
method TDBLookupCombobox.Select and replace it by the following code 
which restores the code before r56990/r55911 for the case that the 
lookupcombobox is not ReadOnly. Your demo works here. Please test 
carefully - as you see I don't have any experience with that ominous 
Unbound mode...



I switched to the latest fixes_1_8 (57037) and replaced 
TDBLookupCombobox.Select with the provided code. After that 
DBLookupCombobox works as expected for me at first try. I use it daily 
and will report if see problem with it.


Thank you!

By default Lazarus projects use

I use the DBLookupComboBox without DataSource always in the past 10-20 
years with Lazarus and Delphi.


From the TDBLookupComboBox's wiki page:

"Unbound use - You can get the combobox to look up values from one table 
without storing the results in another by leaving the DataSource and the 
KeyField properties empty."

[Lazarus] Any tips to speed up Lazarus->GDB debugger?

[Dennis via Lazarus]

I am using Lazarus 1.8 Win64 , FPC 3.0.4.
As with older versions, debugger is very slow (compared to Delphi).

Is there any tricks I can use to speed up the debugger e.g. turn off 
debug info of all lazarus units/object files?


I remember in Delphi 5, they had an option of whether to use Debug dcu 
(of the main VCL units/objects files).
Is there a similar switch I can use to disable debugger in all, except 
my own source code so as to speed up the debugger?

Shared Folders on Dropbox (for now).  GitHub later.

Are there any recommended practices for setting up Lazarus and various
directories that would make this easier?

Got It.

How about Line Endings?

Not really...

There is the fpdebug package (its part of the install). It is faster, 
but very basic, and many things do not work at all.


Well depends what you want to speed up.

The time F9 needs to start your app? Sorry nothing can be done.
Same for stepping with F7/F8.

Note, you can do the next step, before all your watches have been 
evaluated.
If you find it irritating to wait for those, you can open the history, 
stack and watches window, and use the power button to power them off.



Evaluation of watches.
You can compile with DBG_WITH_GDB_WATCHES
Then you can add watches as follow
>-data-evaluate-expression SomeVariable

If you have lots of watches, you should notice that they evaluate faster.
But the IDE will no longer try to deal with the pascal syntax. So you 
may have to add deref of some hidden refs yourself.

To add to my other reply

You can compile LCL, and package without debug info.

See package options for each package, or additions and overrides.
(and you can modify lib path, so maybe keep several versions...)

If you do, you may save 1 second of the start time. (actually not sure 
if the time is saved during start, or at some later point)

Depends on the gdb version. And your computer speed.
With the latest gdb savings will be way below a second
You can also try gdb 8. That may save half a second.

You can use system unit constants which will map to the appropriate 
values on each platform:
System.LineEnding 

System.DirectorySeparator 



Also keep in mind that you can write conditional code aimed at specific 
platforms, for example:

{$IFDEF WINDOWS}
  Path := 'C:\Temp\';
{$ELSE}
  Path := '/tmp/';
{$ENDIF}

Isn't it already there? I don't remember, though, but my Lazarus has them
already.

Many thanks.  Applying the code to my copy of Trunk (and then removing my
TBufDataset workaround) appears to have completely resolved my issues with
TDBLookupCombobox as well.

 Thank you, now i understand.
Yes, xml/ini syntaxes work, only Im confused because ini default 
hiliting is all black (not nice colors for elements in def config).


When I open an XML or INI file, the correct highlighters are picked 
up. Not for JSON, though.

And then lose 10 minutes because you need to trace a routine in the LCL. 
And an hour more because you discover that the routine is actually in 
the RTL ;-)

XML and INI are supported directly, JSON is supported by JScript 
highlighter:


When I open an XML or INI file, the correct highlighters are picked up. 
Not for JSON, though.


As for file filters - we offer *.* so you can open any file without 
problems - nothing needs to be done here.
