Hi,

What is the tool used to make icons for standard Lazarus components ? Every time I need to make an icon for a component, I find myself in the situation that I start looking for a tool on internet.

Should not lazarus come out of the box with a basic tool that allows you to create component icons with the correct sizes ?

Michael.

IMO, inkscape

I use "Greenfish Icon Editor". GPL with FPC/Lazarus sources. http://greenfishsoftware.org/gfie.php

Roland Hahn who designed most of the palette and a good part of the toolbar icons is using Inkscape. This may be a bit surprising because Inkscape is a vector graphics program for svg drawings, but icons are bitmaps. The main advantage is that every feature of the drawing is available as a separate object, not merged together like in the bitmap programs (unless layers are supported). Producing svg vector drawings it is enough to do an image once and export the three resolutions (95ppi, 144pii, 192ppi) from that single source file. Well - in principle because the 150% image usually becomes a bit blurred this way. Roland goes even a step further and does every size individually in order to fine-tune details.  And the final advantage is that we have svg files for the time when a future Lazarus will support to scalable svg images.

In the meantime I tried Inkscape myself for some of my own components, and yes, once I learned the basic operations it is really well-suited.

It really would have to be an advanced program, most of all supporting layers, and I think that this would be too much work. Besides GreenFish there is also LazPaint, both written with Lazarus and are very good.

OK.

Where are the SVG sources for the icons ? I looked but can't find them.

I need to create a new dataset descendent image. It would be good to be able to start from one of the existing SVGs and simply change the text.

So maybe the SVGs of the original icons could be included in the lazarus distribution. That way people can take an existing one and change it.

I believe it.

Yes and no. The goal is to be able to make a minimalistic icon quickly. For this you don't need a full-blown editor. I expect such tool to be included in Lazarus.

For Delphi I still use the icon editor that came with D7. Since they later removed it, I specially saved this program in a separate folder. For example, I have my own TDatasource. I just changed the colors of the TDatasource one.
The icons will not win a beauty prize, but at least every component gets a distinct icon.

Anyway, thanks everyone for the answers ! If the SVG files could be committed, that would be nice.

Michael.

Great ! Thanks !

Now I still need to learn some Inkscape, but that's for later :-)

Michael.

I also use Inkscape and rsvg-convert
 
I have a script for converting all *.svg icons to multiple sizes:  
#!/bin/bash
 
for i in *.[Ss][Vv][Gg]; do rsvg-convert $i -w 64 -h 64 -a -o ../png_all/`echo $i | sed -e 's/.svg$/_64.png/'`; done  
for i in *.[Ss][Vv][Gg]; do rsvg-convert $i -w 56 -h 56 -a -o ../png_all/`echo $i | sed -e 's/.svg$/_56.png/'`; done  
for i in *.[Ss][Vv][Gg]; do rsvg-convert $i -w 48 -h 48 -a -o ../png_all/`echo $i | sed -e 's/.svg$/_48.png/'`; done  
for i in *.[Ss][Vv][Gg]; do rsvg-convert $i -w 40 -h 40 -a -o ../png_all/`echo $i | sed -e 's/.svg$/_40.png/'`; done  
for i in *.[Ss][Vv][Gg]; do rsvg-convert $i -w 32 -h 32 -a -o ../png_all/`echo $i | sed -e 's/.svg$/_32.png/'`; done  
for i in *.[Ss][Vv][Gg]; do rsvg-convert $i -w 28 -h 28 -a -o ../png_all/`echo $i | sed -e 's/.svg$/_28.png/'`; done  
for i in *.[Ss][Vv][Gg]; do rsvg-convert $i -w 24 -h 24 -a -o ../png_all/`echo $i | sed -e 's/.svg$/_24.png/'`; done  
for i in *.[Ss][Vv][Gg]; do rsvg-convert $i -w 20 -h 20 -a -o ../png_all/`echo $i | sed -e 's/.svg$/_20.png/'`; done  
for i in *.[Ss][Vv][Gg]; do rsvg-convert $i -w 16 -h 16 -a -o ../png_all/`echo $i | sed -e 's/svg$/png/'`; done            
 
Yes, non-integer scaling may be blury sometimes but nothing horrible.

I feel with you... Unfortunately every graphics program has its own short cuts and places in the menus and toolbars, and yes, Inkscape, like the well-respsected Gimp, is not a master-piece in user-guidance, at least for my way of working.  Since the icons are stored in universal svg, however, you can also switch you other vector programs instead, like CorelDraw or LibreOffice Draw. But they have other issues...

IMO Inkscape works much better compared to Karbon (if it is what you meant LibreOffice Draw). Therefore I prefer it, even if it is a little stranger (GTK app.) on my Plasma desktop.

Aseprite is brilliant. Included in Linux package repositories too. I use it for pixel art - playing around with game development. There are loads of fantastic tutorials on youtube too.

With IcoFX tool I stopped myself googling (also available in portableapps). It create multiple layers icon according with the OS style. See the screenshots

1.
when the compiler reaches this line,,,

qryMain.AfterOpen:=TB_DPTAfterOpen;

it throws the error:
unit1.pas(190,23) Error: Wrong number of parameters specified for call to "TB_DPTAfterOpen"

2.
TB_DPTAfterOpen is declared as:

TFrame1=class(TFrame)
protected
              procedure TB_DPTAfterOpen(DataSet: TDataSet);
...

3.
qryMain is declared as:

qryMain: TSQLQuery;

4.
AfterOpen is a TDataSetNotifyEvent

AfterOpen: TDataSetNotifyEvent

5.
TDataSetNotifyEvent is declared as

TDataSetNotifyEvent = procedure(DataSet: TDataSet) of object;

Ev seems ok to me. So where is the error?

Thank you

Peppe Polpo

?

Colin

thanks Colin, it worked.

In Delphi you write
qryMain.AfterOpen:=TB_DPTAfterOpen;

but whatever works is ok to me :)

It works also with FPC when using {$mode delphi}

Juha

Yes, it works.

Good to know.

Thank you
