FLTK-C-1.3.3 for FreeBASIC

[Knatterton]

And i personally have only a few areas of interest. Like graphics with Cairo and others, Fltk-c or few projects from Joshy, our hardworking translator. In most threads you will never see me, just not interested. :-)

I myself am using Geany all the time with the cmd-line

Code: Select all

fbc -w all -gen gcc -O 2 fbc_options_10.bas

at the moment and seldom need other options.


The idea would be to take the options window into "FastLighter.bas" and open the .bas files each in a new tab like in "Fl_Tabs03.bas" with syntax highlighting like in "Fl_text_3.bas".

In the options window i would put all activated options along with their parameters in the global array (which Joshy and MrSwiss dislike). If the OK-Button is pressed i would loop through this array and construct the complete cmd-line. Then execute this and compile the active .bas file. But i don't know how to do it in oop style.

[Knatterton]

Sorry writing so much here when obviously nobody is interested. Just want to finish this idea.

You know almost all about about fltk-c, Joshy. But an beginner does not. That's why they often become stuck in a later point of their project. Mostly simple things like closing a window can drive you mad and it takes days, because it is mentioned nowhere.

That's what complex example programs good for. Means, a progam where most of the features in the example snippets put together to form a complete program. This could be used as a base for a step-by-step tutorial. So i think it would be a really good idea to create a complete IDE with fltk-c and ship this together with next version.

Many people have their own windows-only IDE in this forum. What's so special in "ours"? It's platform independent. :-)

[badidea]

... Mostly simple things like closing a window can drive you mad and it takes days, because it is mentioned nowhere..

Not sure if this is a question or remark, but in my code containing a main window and setting window, I just use the small 'x' (often top-left) of the window manager :-)

More serious, in main I call ounce:

Code: Select all

_guiLaunch()

Which is:

Code: Select all

sub _guiLaunch()
	_guiMainDef(1) '1 = show
	_guiSetDef(0)
	Fl_Run
end sub

In settings window code:

Code: Select all

sub _guiSetDef(show as integer)
	pWinSet = Fl_WindowNew(...)
	'other code...
	if (show = 1) then Fl_WindowShow(pWinSet)
end sub

In main window code:

Code: Select all

sub _guiMainDef(show as integer)
	pWinMain = Fl_WindowNew(...)
	Fl_WidgetSetCallback0(pWinMain, @guiCloseMain)
	'other code...
	if (show = 1) then Fl_WindowShow(pWinMain)
end sub

And when closing the main window:

Code: Select all

sub guiCloseMain cdecl (byval widget as Fl_Widget ptr)
	'close all windows
	var  win = Fl_GetFirstWindow()
	while win
		Fl_WindowHide win
		win = Fl_GetFirstWindow()
	wend
end sub

But I wrote the code a few years ago and have forgotten a lot of details about FLTK stuff since.
Also, I have all FLTK widgets global (shared). I did not know to do that differently at that time.

[Knatterton]

Not sure if this is a question or remark,

Both.

The project Fltk-c for FB started in another thread before in Aug 26, 2013 that reached about 50 pages:

https://freebasic.net/forum/viewtopic.php?f=14&t=21548

And now it has 18 pages. But how many people created complete, useful programs with it in these six years and where we can download them?

[jdebord]

I have already mentioned my calculator program:

https://freebasic.net/forum/viewtopic.p ... 87#p208187

I have other programs written with FLTK but they are all french versions so I have to modifiy them.

And BTW, yes I use global variables :)

Great job!

Have just compiled it in Linux Mint 19.2 with FB 1.06.

At "fbc -dll fbeval.bas" i got the error "redefinition of intrinsic", so commented out these two lines:

Code: Select all

'#define True -1
'#define False 0

Then copied the compiled "libfbeval.so" to /usr/lib. Works!

[jdebord]

Glad to see that it works :)

And yes, TRUE and FALSE are already defined in the most recent FB versions.

[Knatterton]

Interesting demonstration for the usage of dynamic libs.

Although i myself only use +, -, * and / and can't test the other functions. :-)

[Knatterton]

Another small improvement:These two programs are meant for users that are searching for toolbar or imagebutton examples. It' s the code from "Fl_File_Icon02.bas" slightly changed and with more speaking names:

Code: Select all

' Fltk_Toolbar01.bas

#include once "fltk-c.bi"

' You can use the Fl_File_Icon class as "normal" icons also.

' test of

' Fl_File_IconNew

FL_WindowEnd win
Fl_WindowShow win
Fl_Run

These could be included in next version.

I understand that I can use Fl_WindowExSetHandleCB to trap window events.
If I trap for the FL_EVENT_SHOW, is this run before or after the call to Fl_Run.

I would like to run a little init code that might create another window, other than the main.

I would say, fltk has all to create a complete program. With a little polish and system it should be possible. To distinguish the Fl_Objects examples from self-created their filenames could begin with "Fltk_", so you always know what type of file this is. Like i do with the Cairo_ examples. This saves lots of time with many files. Similar with filenames like "drawing06.bas". "Fltk_draw_timer.bas" is much more speaking and saves a lot of searching time.

If Fltk would be my project i would be pleased when others are creating complete programs with it. But Joshy seems not to be interested.

But Joshy seems not to be interested.

Do you know how many code I wrote or translated for the FreeBASIC community since last 14 years !

Currently I build the include files for XAUDIO2 (differs for Windows 7,8,10)
I write and cross compile the C++ wrapper and create new include files for latest version of the React 3D physics library (win32/64 Linux32/64)
I write and compile C++ wrapper and create new include files for the Milkshape 3D editor (win32 only)
...

It's up to you all to support all the hard work I made

test all stuff find and report errors
write programs
write help files
...

By the way all the *.bas files I wrote in the fltk-c-1.1.3 folder are not really examples for you users.

It's more a test if I added a command to the C++ wrapper and was not sure does it will work as accepted.

For example no once test all gfx commands and reports any problems they are 2,600 fltk-c commands waiting for testing ;-)

Again you are all free to support fltk-c, happy GUI coding.

Yes, i have already started a few files, i will post them when ready.
