10. The holy grail
The holy grail is all about combining knowledge. To find spots in your gui where bash can fuel the gtk-theme or svg to push gtkdialog's limitations. Be aware that both gtk-themes and svg images are basically raw text files. Since bash is a great tool for text managing, it is easy to code a text-file depending on user/system input.
The example is taken from the app 'pFind'. The screenshot shows that pFind has detected 419 files with the pattern "puppy". 2 audiofiles, 67 images...
These are <button> widgets with no button decoration (relief="2"), and no <label> defined. The result for the user is a clickable svg that highlights at mouse hovering, and has tooltip text.
The svg contains info about
- Category with a representing icon
- Number of hits. If 0, the svg is grayed out
- Active category in the list to the right is shown by the arrow
<?xml version="1.0" encoding="UTF-8"?> <svg xmlns="http://www.w3.org/2000/svg" version="1.1" width="100" height="30"> <rect width="80" height="30" style="fill:#ddd; fill-opacity:1; stroke-width:0" /> <path style="fill:#ddd; fill-opacity:0.8; stroke:none" d="m 80,0 20,15 -20,15 z" /> <path style="fill:black; stroke:none;" d="m 5,11 0,8 4,0 7,6 0,-20 -7,6 z M 20,9 c -1,-1 -2,1 -1,2 l 0,0 c 1,1 1,3 1,4 0,1 0,3 -1,4 -1,1 0,3 1,2 2,-2 2,-4 2,-6 0,-2 0,-4 -2,-6 z m 4,-3 c -1,-1 -3,-1 -2,1 3,3 3,5 3,8 0,3 0,5 -3,8 -1,2 1,2 2,1 3,-4 3,-6 3,-9 0,-3 0,-5 -3,-9 z"/> <text x="75" y="20" style="fill:black; font-family:DejaVu; font-size:14; text-anchor:end;"> 2 </text> </svg>
The gtkdialog code for the button is extremly simple. What makes the code long is to refresh all <button> widgets when clicking. We have to rebuild the svg for all of them to make the new active svg/button get the arrow.
<button relief="2" tooltip-text="'$(gettext "Sound files")'"> <variable>BUTTON_MUSIC</variable> <input file>/tmp/pfind_MUSIC.svg</input> <action>func_viewMusic</action> <action>func_buildSvg</action> <action>refresh:TREE</action> <action>refresh:BUTTON_ALL</action> <action>refresh:BUTTON_MUSIC</action> <action>refresh:BUTTON_PIC</action> <action>refresh:...</action> </button>
