Description Mohd Asif Ali Rizwaan 2006-10-11 19:17:33 UTC
Version:           2.0.4 (using KDE 3.5.4, Frugalware Linux)
Compiler:          Target: i686-pc-linux-gnu
OS:                Linux (i686) release 2.6.18-fw1

It is very confusing when we try using arithematic operators (+-*/) in kcalc. KCalc should proive some clue that the operater is used.

How to reproduce:

1. open kcalc
2. type 6
3. type +
4. type 6
5. type enter

Please observe in the above calculation, that after pressing '+' sign, kcalc doesn't show '+' in the Display.

Expected Behavior:

1. Symbols and Colors should be used to make the operations clear.

2. e.g., pressing + should show '+' sign below "Dec" in the view

3. Also using a different color or flashing with different color when an operator is pressed will help the user to know that the operator is inputted properly.

I would request, to change the Light-Green Color to Yellow when operator is entered.

for example:


2 -> background light green
+ -> background light Yellow 
3 -> background light blue
5 -> background Light Red to signify result.

the colors could be changeable in settings. this way the user is more informed about the calculation.
