New to Lazarus, questions on Widgets

[BlackSun]

Hello there,

I am a big Delphi fan, but a bit depleased with their .net orientation, lack of x64 and other OS support support, so I got really interested in FreePascal, and of course Lazarus.

I plan to write an app that run on Windows, Linux and MacOS at least, and was thinking about using GTK2 as a set of widget, it is supposed to run on the OS I'm interested in if I am not wrong.

My app is going to have skinning support, and I got GTK2 themes working using the libraries there: http://members.lycos.co.uk/alexv6/

Now my questions:
- I tried to look for the status of the current GTK2 development, but didn't find anything really new.

- I wrote a small test app, work fine except for two problems (my main question for this topic in fact): the form on runtime is created in another form container

(http://www.corecodec.org/~blacksun2/bordel/gtk2.png)

Now for the other problem, when the mouse is over the app window, it is using the gtk cursor (a black one), is there any way to prevent that ? Btw my app currently run on Win32, didn't test on another OS yet.

- How to set a GTK2 theme for an app ?

Many thanks for helping me

I don´t know how to set a gtk2 theme, but you can go to this website: http://www.gtk.org/

On the documentation section of gtk website you may see the following links:

http://www.gtk.org/api/
http://www.gtk.org/tutorial/

To use gtk function simply include gtk in your uses clause.

But know that gtk2 is not absolutely problem-less yep. Thought it is close to getting ready, gtk1 applications are much more stable for now.

Also remember that there is no need to link to gtk2 on windows. You can link to windows API with the exact same source code =)

Very nice, hum?

Just remember to use strip: "strip --strip-all <executable file>" and "upx <executable>"

This can make a 6MB executable go down to 700kb. I even got a 400kb graphical exe on Windows.

UPX has a incredibly small drawback on the executable load time.

The problem of the double windows you see is a win32 issue.
Win32 has no problems in having a form as child while on other widgetset it is a problem.
Don't use a borderless form as child in a form (asif it was a frame or a mdichild)
