Subject description: drop down selection window height		  
First, I am not going to post an example for this since the example Barry posted in Cutting Edge - Gtkdialog can be used to show what I am talking about.
In the Country selection one, if one clicks on the down arrow to show the item choices, a selection window is shown that has a height that takes the full height of my display with additional up and down arrows at each end of that window.
My question is:

Since one has to use the additional up/down arrows in that window, is it possible to specify the height of it?
It would sure help in cleaning up the looks of it for selection of country/language/keyboard if the popup selection window was a given height.

I tried changing <comboboxtext> to <combobox> throughout the script and to me, I think it helped. The height is still there in the selection windows, but the change gave a vertical scrollbar that helps in locating a selection.

I was trying to find a way to center the text in a label in a tree list, but came across this by accident
Code:
<tree>
      <label>'"_MY LIST OF STUFF"'</label>

this gives the label bar a keyboard control of Alt+M, I didn't see this mentioned anywhere else, so I thought I'd pass it on.

updated wiki

http://puppylinux.org/wikka/PBurn

is this limitation still true?

Quote:
It will only perform the writing function with a blank disc, i.e. the disc is either new, or, as in the case of a re-writable disc, it has been erased first.

What is the origin for that statement? (If it is in the docs, I should remove it) It is not true. In those cases where burning require a blank disc (ie. audio-CD), user will get an option to erase disc before burning.


Thank you for maintaining the wiki !!!!!

(Opps, I was meant to post in PBurn) anyhow, the origin is unknown to me - probably from a very old version of PBurn. Fixed it now ; -)

I'm trying to find a way to include a progress bar into a small GUI.

It needs to be able to show copying and burning DVD's

I'm trying to use the following example as a starting point:

Code:
#! /bin/bash

export MAIN_DIALOG='
<vbox>
  <frame Progress>
    <text>
      <label>Some text describing what is happening.</label>
    </text>
    <progressbar>
      <label>Time left</label>
      <input>for i in $(seq 0 10 100); do echo $i; sleep 0.3; done</input>
      <action type="exit">Ready</action>
    </progressbar>
  </frame>
  <hbox>
   <button cancel></button>
  </hbox>
 </vbox>
'
gtkdialog --program=MAIN_DIALOG



How do I calculate the percentages and parse the info to the progress bar?

Thanks

smokey01,

You can find an example of a progress bar with percentages in PupsaveRestore by 8-bit.

See -
http://www.murga-linux.com/puppy/viewtopic.php?t=72153

Thanks seaside.

I have already seen 8-bits code but am looking for a simpler example.

There is a simple progress bar example in /usr/share/doc/gtkdialog3 (in the devx)

Hi

Is it possible to show variable or function's result as a button's label (<button></button>)?
I tried with <input>, <input file...>, <label> and nothing works...

Thanks in advance.

Greetings!

SFR,

Perhaps this is what you want-

Code:
#! /bin/bash
LABEL=`echo result of some program`
export MAIN_DIALOG='
     <button>
      <label>'"$LABEL"'</label>
      <action>echo new label '"$LABEL"' created</action>
    </button>
 
'

gtkdialog3 --program=MAIN_DIALOG


This would take the result of some program (in this case the phrase "result of some program") and assign it to the variable LABEL. Note that $LABEL is surrounded by double quotes followed by outer single quotes.

Cheers,
s

This is exactly it, thanks very much!
I was stuck focusing myself on functions, your method is much easier. Smile

PostPosted: Sat 14 Jan 2012, 22:29    Post subject: timer example  
This is a simplified timer widget example. The timer widget is not visible.

Requires gtkdialog >= 0.8.0 (you may need to change the call to "gtkdialog4" in wary/racy/lupu)

Thanks to technosaurus for the text2svg function. (@ techno, the header is needed to stop gtkdialog and other gtk apps from segfaulting, coutesy of thunor).


Code:
#!/bin/bash
# timertest

# Functions====================================================================
text2svg()
{
#generate an image
WIDTH=$(($(echo "$1"|wc -c)*19))
T=35
BG="$2"
echo '<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
  <rect width="'$WIDTH'"
     height="50"
     x="0"
     y="0"
     style="font-size:'${T}';fill:'$BG';fill-opacity:0.75;fill-rule:evenodd;stroke-width:3pt;"
     id="rect1" />
  <text
     x="0"
     y="35"
     style="font-size:'${T}';font-weight:normal;fill-opacity:0.75;stroke-width:3pt;font-family:helvetica;"
     id="text1">
    <tspan
       id="tspan1">'"${1}"'</tspan>
  </text>
</svg>' > /tmp/${3}.svg
}
export -f text2svg

randomfunc(){
echo "some random number $RANDOM"
}
export -f randomfunc

pixfunc(){
DATE=`date`   
text2svg "${DATE}" "#ADD8E6" date
   }
export -f pixfunc
