Dim rbcs As New RBCSize
 
rbcs.Size("/Users/qbap/Downloads/", 1) // (folder or file location, 0 = size in bytes or 1 = size in kB)
 
MsgBox Str(rbcs.Data) + " kB" //convert Integer value to String and display a MsgBox info

Of course using other Classes in REALbasic looks that same. If it’s a button class etc. when you will add it to Project Tab you will see it in Window GUI Builder Tab in All Controls. Now you can simply drag and drop it to the Window1 Class and use it like other Controls.

iSightCamera Class features

The video image can be displayed in a REALbasic Window or in a Canvas. You can adjust the size of the video image. You can adjust the ‘shutter speed’. By default, the live image runs as fast as your machine will allow. But if for some reason you want to use less cycles, you can slow how often the live image is captured. Errors in the class are logged to the Console. A message box will be displayed if you try and create an instance of the class and it fails. This can happen if you don’t have a camera or if the one you have is already in use.

What can we do with Timer Class?

The answer for this question is very easy – everything we like. For example we can use it for closing our application after 10 minutes from start, we can monitor some changes (keydown events, files changes), count time and speaking in one word one more time executing some code after a specified period of time (Period: 1000 = 1 second) .

Shutdown application after 10 seconds

Add to Window1 a Timer Class from Control Tab and set the Period Property to 10 000. Change also the Mode to 1- Single (this will start only once the Timer). Double click on Timer Control (Timer Sub Action()) and enter there:

1

Quit

Keydown events

The following code in the Action event of a Timer detects whether the Up, Down, Left, or Right arrow keys are pressed and display you a info in StaticText1 Control. Please remember to change the Mode Property to 2 – Multiple and the Period to for example 10.

if Keyboard.AsyncKeyDown(124) then
StaticText1.Text = "you have pressed right arrow key"
end if
if Keyboard.AsyncKeyDown(125) then
StaticText1.Text = "you have pressed down arrow key"
end if
if Keyboard.AsyncKeyDown(126) then
StaticText1.Text = "you have pressed up arrow key"
end if

Definition of Class by Wikipedia

In object-oriented programming, a class is a programming language construct that is used as a blueprint to create objects of that class. This blueprint describes the state and behavior that the objects of the class all share. An object of a given class is called an instance of the class. The class that contains that instance can be considered as the type of that object, e.g. a type of an object of the “Fruit” class would be “Fruit”.

Creating a Class in REALbasic

Run REALbasic IDE and go to Project TAB. Click there on Add Class button and select created Class1.

Now go to Property and Value and change the Name from Class1 to cHTTP and add to Super value HTTPSocket. Double click on cHTML Class in Project TAB.

Data = Me.Get ("http://tutspolis.com", 3 )
 
Me.Close

The HTTPSocket has got a option called Get with will simply in this case get the html code of indicated URL. Our class will download for us the HTML from tutspolis.com.

Using a Class in REALbasic project

Now in GUI builder we will have a new control called cHTML. We can simply drag and drop it to our Window. To try out our new class add to the Window controls TextArea and PushButton. Double click on PushButton and enter the code:

Dim tuts As new cHTML
 
tuts.downloadHTML // get the html code
TextArea1.Text =  tuts.Data // display it in TextArea control

When we will press PushButton, TextArea will fill up with HTML code of tutspolis.com home page. You can now for example render the code, modify it or get only some important for you information. It can be also done in class cHTML on other Method.
