Twenty years | REALbasic | Real Studio | Xojo

Twenty years | Realbasic | Real Studio | Xojo


Xojo 20

Realbasic

In 1997 FYI Software, founded by Geoff Perlman, bought CrossBasic, which had been marketed by its author Andrew Barry as a shareware product. CrossBasic got its name from its ability to compile the same programming code for Mac OS and the Java virtual machine (although the integrated development environment was Mac only). A public beta was released in April 1996. The CrossBasic name was trademarked by another company, so the product was renamed REALbasic.

Real Studio

In 2010, to combat the perception that REALbasic was similar to the original BASIC, it was renamed Real Studio.

Xojo

On June 4, 2013 Real Software officially changed their name to Xojo, Inc. and Real Studio was renamed Xojo.

CGTEXT CLASS

This is a Mac only REALbasic class that will give you the ability to draw text in a Rb Canvas with more control and functionality using the Core Graphics framework in OS X. The class is free, but is encrypted. The download includes a demo project.
The class allows you to set the following.

SSCGText

*Character Spacing (single). The default setting is 0.25.
*Dash (Boolean). The pen style on TextFillStroke Fonts can be drawn with a dashed styled. The default setting is False.
*Drawing Mode (String). This setting determines the style of the font drawn. Available settings are, Text Fill, Text Stroke, Text Fill Stroke. The default setting is Text Fill.
*Fill Alpha (single). The color of the fill can be assigned an alpha value. The default setting is 1.0.
*Fill Color (color). The color of the fill can be assigned a color. The default setting is black.
*Font Name (string). You can assign the PostScript name of the font family. he default setting is “Verdana”.
*Font Size (single). You can assign the size of the font to be drawn. The default setting is 11.0.
*Pen Alpha (single). The pen alpha value can be assigned a value. The default setting is 1.0.
*Pen Color (color). The color of the pen can be assigned a color. The default setting is black.
*Pen Width (single). The pen width can be assigned a value. The default setting is 0.50.
*Rotate (single). The entire CGText object can be rotated. Positive values rotate clockwise. The default setting is 0.0.
*ScaleX (single). The entire CGText object can be scaled in the X direction. The default setting is 1.0.
*ScaleY (single). The entire CGText object can be scaled in the Y direction. The default setting is 1.0.
*Shadow (Boolean). The entire CGText object can given a shadow object. The default settings is False. When set to true the values for the shadow are, offset width 3.0, offset height -3.0 and blur value of 1.0.
*Should Alias (Boolean). The CGText object can be drawn without anti alias, i.e. jaggies. The default settings is False.
*Text (String). This is the text that the CGText object will draw. The default settings is empty (“”).
*Draw (Method). This is the method you call to show your CGText object. This Method should be called in the Paint Event of its associated Canvas.
*Constructor (Canvas). The CGText object is created by passing it the Rb Canvas you want it to be drawn in.

IPHONE LIKE OPENGL

This is an OpenGL project that ports the Xcode projects from Jeff LaMarche. Jeff has a fantastic series of tutorials about learning OpenGL on the iPhone. Please see the URL listed in the project file. You can now follow along on your desktop using REALbasic, using this project as a guide on how to adapt the code Jeff posts. The iPhone because of it limited memory uses a subset of the full OpenGL functions on the desktop. The iPhone uses a more modern approach to funneling the geometry via array pointers, MemoryBlocks in REALbasic. The original method of learning OpenGL using your drawing calls between the GLBegin and GLEnd calls is soon to be deprecated, so learning arrays is the way to go if you want to stay current with the OpenGL renderer.
I wrote this on my Mac and have not run it on a PC. The methods used to pack everything in to MemoryBlocks is done crudely. It should give you some idea’s on how to optimize with classes to get things done in a object oriented manner. The download has 13 different projects through Lesson 4.
