Wat moet jy weet van Delphi?
Graad 10
Algemeen / Inleiding tot programmeringsomgewing
GUI
Event Handlers
Events such as OnClick, OnClose,
OnShow, OnMouseMove
Components: Edit, Checkbox, Radio Group, Label, Panel, Listbox, RichEdit,
Memo, BitButton
Form class
Datatipes en veranderlikes
Integer, Real, Character
String, Boolean
Scope of variables
Toevoer en afvoer
InputBox
Input and output components and
properties: Edit, Checkbox, Radio Group, Label, Panel, Listbox, RichEdit
and Memo
Formatting output in RichEdit using tabs and new line / return characters
Operators en verwerkings
Mathematical: +, -, *, /, Div, mod
Relational: <, >, =, <>, <=, >=
Boolean: AND, OR, NOT
Precedence and brackets
Simple string manipulation: Length, Pos, Concat (+), Uppercase, Copy,
Delete, Insert, Val
Includes data type conversion such as IntToStr, StrToInt, StrToFloat,
StrToIntDef, FloatToString, FloatToStrF, to be able to do mathematical and
string manipulations
Kontrolestrukture
Sequential
Selection
- Single selection IF
then
- Double selection IF
then
else
- Multiple selection Case
Repetition
- Counting For
do
- Conditional While
do
- Repeat
until
Klasses en objekte
Form Class
Metodes (funksies and prosedures)
Mathematical such as sqr, sqrt, round, trunc, abs, random, power, min,
max, frac, int, odd, dec, inc, etc .
Modules
- Simple user defined functions and procedures using parameter passing
e.g.
CalcInterest(12) if 12% interest should be added, GetMonthName(6) to
determine the name of month number 6. (not reference parameters)
Call functions and procedures
GUI (GGK)
IDE Delphi
Defensiewe programmering
Meaningful error messages to user e.g. message dialogue boxes
Error checking techniques
- Check that data has been entered / compulsory fields
- Check that the right type of data has been entered e.g. Real or Integer
using VAL-procedure
- Check that data is valid (falls between a certain range)
- Use the MaskEdit to ensure valid data (for use in projects only)
Algoritmes / probleemoplossing en fundamentele programmeringskonsepte
Swop two values
Determine smallest, largest value of more than two values
Isolate digits in an integer value
Determine whether a number is a prime number, even, odd number
Determine whether a number is a factor of another number
