Script refreshes a table in a notebook

[don570]

I wrote this example to learn how to refresh a table widget that
is located inside a notebook. A list widget sends the signal.

The table gets its data from the following line...

Code: Select all

<input file>/tmp/population/default</input>

The key is to understand the following lines in the script...

Code: Select all

				
				<action>cp -f /tmp/population/"$LIST" /tmp/population/default</action>
				<action>clear:TABLE</action>	
				<action>refresh:TABLE</action>	
				<action>refresh:ENTRY</action>		   
		

The first action directive will make the change in the default file
which has the population data for the province.

The second action directive allows the rebuilding of the table,
since I found that a simple refresh wasn't enough. (Remove this line
and observe that the population data is steadily added to bottom)

<action>refresh:TABLE</action> --> sends refresh signal to the table widget.

<action>refresh:ENTRY</action> ---> sends refresh signal to entry widget

I've continued to work on this example . I added the province populations
together and calculated the total.

I do this at beginning of script. I experimented with an array.

I made the array with command substitution which is very powerful.

Code: Select all

YEAR=( `function_total`)

where function_total simply prints the individual province populations
to the screen

I removed the comma in the number with

Code: Select all

YEAR_mod=${YEAR[$PROVINCE]//,/} # remove comma from population

I corrected the script 'population2.sh' to show Canada's population correctly.

I didn't make the loop correctly to change PROVINCE.
Therefore I was adding Alberta's population 10 times to find Canada's population.

I just needed to change a line to ...

Code: Select all

YEAR_mod=${YEAR[$PROVINCE]//,/} # remove comma from population
