Graphics in Freebasic

Gablea · Post by **Gablea** » May 03, 2010 21:09

Hi all,

How do I handle graphics in Freebasic?

Basiclly I want to know say I have a screen with lots if information
being displayed and I then display a Error box how do I restore the
screen information that was below the error box?

Thanks

Andy

There's plenty of ways to render graphics...

Cross-Platform GUI: FB gfxlib2, GTK+, Qt, OpenGL, wxWidgets
Windows: DirectX, Windows API

Are you already familiar with any tools, and what OS are you developing on/for?

I'm not completely sure what you want. Do you want a "pop-up window" like you get with Windows error messages? example

OK

Example time :) Display 1 is what is normally displayed when ever any items are scanned (

When a item is scanned that is age limited the Till will show Display 2

the cashier would say YES to the age request and they would then see image 3

The Targerted OS will be
> DOS (first off)
> Windows
> Linux

Hope that helps

Hmm...

1) There's no built-in GUI with Freebasic...

2) How long have you been programming, to give us an idea here...

3) Do you need an editor? I have spotted about a dozen spelling/grammar mistakes...

Gablea · Post by **Gablea** » May 05, 2010 23:01

1. I am doing the GUI work all myself (drawing etc)

2. I have been programming in general for 15 years (Normally use Visual Basic but want to get a grip on FreeBasic)

3. I know there are spelling errors the screens are JUST for example.

Would your GUI require the use of a mouse and actual clickable windows? If not, what you can do is combine a freetype wrapper/DLL (there's one for Freebasic somewhere here in forums) with static pictures and FBGFX primitives (line, circle, etc.).

Gablea · Post by **Gablea** » May 05, 2010 23:23

No this version would not need the mouse as it is all keyboard based (as it is a EPoS Till system)

but I will be doing a touch screen version of my EPoS Software (at some point)

If I wanted to display messages like Windows (the question mark etc) I would asume I would have to draw them manually (by code)?

agamemnus · Post by **agamemnus** » May 05, 2010 23:27

You can use the freetype wrapper/library that I mentioned earlier to draw text to screen. You'd have to position the borders of your windows and stuff manually though (like in a "drawWindow" function). You'd also of course need to figure out how you want key input to work. I suggest using multikey.

That not a problem but I am worried about the blocky text I have for the total etc at the top of the screen.

I have looked at at that XFont but I can not seem to figure out how to make the font larger and keep it smooth (in the vb version the total label is Arial Narrow and the font size is 28) how would i do that with the XFont?

Er, I was not using xfont. I was using this:

http://www.freebasic.net/forum/viewtopi ... t=freetype

I did make a lot of changes but I can't find the code ..

Atm I'm just using a gui that works with 3d graphics settings...

Hi
This is the closest I can manage with just FreeBASIC.
Ive posted this font thing before under tips and tricks, with instructions, but it's only a bit of fun, not meant for till readouts or whatever.

Couldn't you use a combination of SCREENSET and SCREEN COPY to achieve something?
Display one screen while working on another, then swap back and so on.

See WIKI http://www.freebasic.net/wiki/wikka.php ... gScreenset

I have looked at at that XFont but I can not seem to figure out how to make the font larger and keep it smooth (in the vb version the total label is Arial Narrow and the font size is 28) how would i do that with the XFont?

When you scale the font with font.drawstring (,txt,xpos,ypos,xscale,yscale), you still get blocky edges. The way around this is to convert the font with the converter application (http://xaviorsoft.freebasic.net/fbprodu ... nv_win.zip) to the size you want.

If you want various font sizes, create the corresponding .xf files (e.g. ArialNarrow14.xf, ArialNarrow28.xf), load them into xfont with font.loadfont(filename, fi) and use the one you want with font.fontindex = fi

If you create .xf files of a font in various sizes, there is no reason why it wouldn't.
