fpgui problems
lazarus / 64-FPC development

Hi,

Having managed to cross compile for win64 using gkt2 widget set , the
resulting exe failed to get off the ground.

I installed gtk2 on the target system but when I ran my exe I just got
a banal error box that "it failed to start correctly". Which has to be
the most useless indication of what is wrong. I guess that is the kind
of reason why I use linux instead of windoze.

So I decided to use fpgui which should produce a totally self-
contained exe which is more consistently cross-platform.

I grabbed the latest source from
http://wiki.lazarus.freepascal.org/fpGUI

This fails to build because it is missing lhelpcrontrols 

This is allegedly in the lazarus source tree but I don't find a
package file as described here:
https://forums.opensuse.org/showthread.php/467141-Lazarus-can-t-
install-help-files

That is rather old , so can anyone say how to get this running. I was
not expecting to have to go on another paper chase. I thought the
fpgui was built in to Lazarus. Why does it not build directly?

Thanks for any help.

If I read correctly, you're rebuilding your project using fpgui, but
it was originally designed to use GTK+, isn't it?

As far as I know, LCL with fpgui isn't complete.  I mean, not all LCL
components are available or work with fpgui.  Also fpgui has its own
GUI designer, you should use it instead of Lazarus'.

If you look at the svn log than you see the last non general
modifcation is april 2015. The one before that march 2013.

Doesn't seem that lcl-fpgui gets too much love.

No it doesn't - it is in need of a maintainer that can complete the
missing parts (TLabel being the biggest cause of problems). I
recommend using fpGUI directly without the  need of LCL.

I think QT  better in cross

Maybe for usage with LCL yes. But then you have to contend with
shipping multi Megabytes of DLL's with every little application you
create and deploy. No more small apps. No more simple deployment.
fpGUI is 100% cross-platform and no external support DLL's are
required.

The LCL-fpGUI will be a huge improvement to LCL in general (once
someone completes the implementation), as it will be the only LCL
widgetset with no external support DLL's, bug fixes in LCL or the
toolkit can be applied and shipped immediately (no need to wait for a
Windows update or new Qt release), and it will be the most consistent
across all platforms.

The LCL-fpGUI widgetset is not fully implemented yet. Many Windows
centric API's are not implemented yet, and TLabel (which is amazingly
complicated in LCL) is not yet implemented and causes a runtime crash
when used in a application. Many other parts or components are working
though. It just needs a maintainer that knows LCL (better than I) to
implement the remaining bits. I rather spend my time improving the
actual "pure" fpGUI Toolkit.

@Graeme FP-GUI Very cool and I use it in my projects 
I think it's the only thing I've relied on in linux .even in other
platforms
Because the Widget qt-gtk in Linux has become unbearable (frequent
updates ABI-API Break Every few months)
I  trying to add languages RTL to fpgui -

I trying collecting information about wayland in linux

I hope that the project will continue and progress and remains simple
and beautiful code

Thanks for using it, and I'm glad you are finding it useful.
