I wrote simple graphic program in Gtkdialog and this is crazy, but...it works!
It uses <button> widget as a drawing area (that's why "BDraw").

Take a look at the screenshot; the toolbox area contains (from left to right):
- current shape
- stroke width
- transparency level
- stroke color
- fill color
(next row):
- Undo - delete last drawn object, doesn't work with Load & Save
- Load - load a picture, only .bdr format is accepted (well, it's SVG really, but has specific arrangement of lines)
- Save - save as .bdr (for further editing) or as .png (you can choose output resolution)
- Quit

Few words about drawing:
When you choose, eg. Line or Circle, then press the mouse button on starting point, drag cursor to the ending point and release button.
But there are two exceptions:
1. Text - press and release the button on starting point; this point will become the bottom-left beginning of the text.
Then choose a font (avoid fonts with digits in their names, they won't work [EDIT: they work since v1.1]), style and size and in the next window enter some text.
2. Arc - press the mouse button on starting point, drag cursor to the ending point and release button, then move cursor to another point and press space [EDIT: since v1.3 - press right mouse button].
(Then you can move cursor to another place and press space again, and so on.)

The drawing area is fixed to 512x512, but it doesn't matter IMHO, since it's vector graphic. As I wrote above you can adjust final resolution while exporting to PNG.

Hint: since you're drawing within a button, it blinks on hover and clicking. To avoid this, just draw filled rectangle that fills all space. This will also remove default transparency of the background.

Requirements:
- Gtkdialog >= 0.7.21 (version 1.0)
- Gtkdialog >= 0.8.0 (versions >= 1.1)
- Gtkdialog >= 0.8.1 (versions >= 1.3)
- base64 (versions >= 1.4)
- Xdialog
- rsvg-convert (for .png output)
- xwininfo
- getcurpos
- awk, sed, and so on.
(all of these should be already present in most/all of recent Puppies)

I've attached standalone, gzip'ed scripts - unpack, make executable and click to launch.

I didn't make a pet, but if someone could kindly make a nice icon for this app (I simply can't draw!) then I'll do it.

Tested on:
- Slacko-5.3.3, 5.4, 5.5
- Lupuplus-528.005
- Precise-5.4.1
- Akita-beta13
- FatDog64-601
- Carolina-0.0.3
- uPup-Precise-5.4.X.4

Hello,
Amazing.. Simply amazing..
Who would have thought... Well, you of course..
Ohh, the possibilities....
Been playing with gtk lately..
I believe we yet just touching on what it can do..
All the parts are there, its just figuring out creative ways to use them..
Like this...

I`ve already got ideas for this...

Dear SFR,

Yes, amazing! Congrats.

With kind regards,

Thanks guys!

I still can't believe it works...
The one who discovered how to draw on screen borders in C64 must have felt similarly.

Greetings!

Brilliant!

zigbert (who happens to be an artist, major gtkdialog fan and svg fan) will fall in love with this!

[sc0ttman]

Oh. My. Word.

[vovchik]

Dear SFR,

I wonder whether I shouldn't try to port your code to BaCon. It is brilliant (yours), but we would get a real speed increase and, if UPX'd, it would be about 7-10k and be a very responsive little draw program. What do you think?

With kind regards,
vovchik

Refreshing!

Sometimes, codelines get you in a good mood.

Dear SFR,

I do not know how to tell you that you have uncovered something like quantum mechanics within the GTK button widget. Lovely And I worked for decades at the IAEA and did their first TCP/IP. You captured something essential. Nice

With kind regards,
vovchik

SFR, I just saw this and had to say-

This is the first drawing program that made me actually feel like drawing something (not that anyone else would share that interest after seeing how I draw....)

Very clean, attractive, and cleverly done.

Hats off to you,

Regards,

The tips-thread is a bit old - it was written in those days before Thunor stepped up. Gtkdialog was not that powerful, and we needed more workarounds.

Some thoughts:
- I usual align widgets to the left by including a text widget. <text space-expand="true" space-fill="true"><label>""</label></text>
- You can make the drawing size larger than screen-size by setting the <button> widget inside a <vbox scrollable="true">
- I think it would be possible to use a <pixmap> widget instead of the <button> for the drawing. gtkdialog supports <eventbox> which can add <actions> to nonactive widgets like the <pixmap>.
- The <timer> can be updated more frequently than each sec. <timer visible="false" milliseconds="true" interval="100">

Hey Zigbert.

[Geoffrey]

Good stuff, tried it in Carolina with gtkdialog version 0.8.3 r473M, it all works.
