Introduction
PocketC Architect is the evolution of PocketC. PocketC Architect is a programmer's tool with a powerful language and a rich, easy-to-use, object-oriented API. Applications written in PocketC Architect can be compiled on a Windows desktop or directly on a Palm OS device.
Users of PocketC 7.1 or earlier gain huge advantages by using PocketC Architect. Most of the features listed above were not available in PocketC, including the rich object-oriented API, the object-oriented language features, the resource syntax for defining forms, and a more productive, intelligent desktop editor.
Users of OrbForms Designer can compile their application with little or no modifications, because PocketC Architect uses the same OrbC compiler and runtime originally created for OrbForms. Using PocketC Architect allows an OrbForms Designer user to compile their application directly on a Palm device.

PocketC Architect Desktop
PocketC Architect Desktop is a Windows-based editor and compiler for the OrbC language.
Selecting Project | Build Project compiles the current project file using the
settings in the Compile dialog and the properties in the @app
resource. The first source file opened is considered to be the project file. To
explicitly change the project file, select Project | Set Project File or
right-click within a file and select Set as Project.
The compile dialog gives you two options:
PocketC Architect uses three file extensions. The compiler and editor treats all files types the same, but their intent is as follows:
When you place the cursor on a function name, it displays the function declaration along with short documentation. The documentation for built-in functions is provided by the compiler. However, you can add documentation to your own functions very easily by adding an @doc directive before the function definition. For example:
@doc "Create a new button"; addButton(int x, int y, string name) { ... }
The application's .prc will be automatically installed on the emulator or simulator if it is running. If the .prc file on the device is in use (i.e. the application is running), the file will not upload successfully. Select Options | Upload on Build to enable or disable this feature.
PocketC Architect can automatically look for updates each time it is run. Select Options | Auto Update to enable or disable this feature. Checking for updates involves downloading a version info file from the OrbWorks server. No personally identifiable information is transfered.
To compile a project from the command line, you can use the included command line compiler, oc.exe.
oc.exe -pocketc [-standalone] [-debug] project.ocp
The -pocketc switch must always be used to provide PocketC compatibility. The remaining switches relate directly to the options specified in the Compile dialog when building from the editor.

PocketC Architect for Palm OS
PocketC Architect is a PalmOS-based compiler for the OrbC language.
Source code can be copied from your computer by running the Palm Desktop application, creating a new memo, and copying the source code to the new memo. PocketC architect also supports PDOC files, such as those created by Qed, SrcEdit, or TealDoc.
A PocketC Architect application can be written as a memo or a PDOC file. When
using a memo, the first line of the
source code must be a
//-style comment which states the name of the file with a .ocp or .oc extension. If the source code is a
doc file, it's name must end in .ocp or .oc in order to be
displayed in the source code list.
Example: "// Hello World.ocp"
.
You may also write source code on your computer, copy it to a memo (with the Palm Desktop
software), and Hotsync.
Select the source file that you would like to compile, and press the Compile button. The source code list displays all source files that end in .ocp or .orb (to make compiler OrbForms applications easy). If the Show classic PocketC checkbox is checked, all memo's that begin with // and all docs that end in .c or .pc will also be displayed in the list.
Selecting the Debug checkbox enables all the runtime features provided by the debug support.
Once an application is successfully compiled, return to the application launcher to run it. In the case of an error, an alert will popup to indicate the location and type of the first error, with an option to jump to the error location.
If you are developing an editor, you can launch PocketC Architect to compile a given file. To do this, use the code snippet below to pass the name of the file (as it would be displayed in PocketC's source code list).
#define sysAppLaunchCmdCompile (sysAppLaunchCmdCustomBase + 1) char* name = (char*)MemPtrNew(33); StrCopy(name, "NameOfFile"); MemPtrSetOwner(name, 0); // so that the OS doesn't clean up when the app exits AppLaunchWithCommand('PCAr', sysAppLaunchCmdCompile, name);
This will launch PocketC Architect and begin compiling the file specified. If you would like PocketC Architect to also give you the results of the compile, use this code below:
#define sysAppLaunchCmdCompileAndReturn (sysAppLaunchCmdCustomBase + 2) char* name = (char*)MemPtrNew(38); // room for file + creator id StrCopy(name, "NameOfFile,<id>"); MemPtrSetOwner(name, 0); // so that the OS doesn't clean up when the app exits AppLaunchWithCommand('PCAr', sysAppLaunchCmdCompileAndReturn, name);
This will cause PocketC Architect to compile the specified file. After the compile, it will launch the app whose creator id is specified after the comma in the command line. In the snippet above, the creator id is "<id>". When the specified app is launched, it will be launched with the a launch code of 0x8001 and a parameter block which is a string containing the results. The results string is either "0" if the compile failed, or "1,<id>" if the compile succeeded. If it succeeded, "<id>" is the creator id of the application just compiled.
Calling the compiler in this way can also be done from an OrbC application using the launchCustomString() function. For example, to compile "file.ocp" from an application whose creator id is "Shll", use this code:
launchCustomString("PCAr", 0x8002, "file.ocp,Shll");

Creating an application
Creating an application with PocketC Architect is done by declaring the application properties, declaring the forms and controls, and implementing handlers for the events. This topic walks you through these steps to create a simple application.
The first step in creating an application is to declare the app and set its properties. To do this, use the OrbC resource language, for example:
@app myApp { creator = "MyAp"; // creator id name = "App Name"; // display name dbname = "AppName-MyAp"; // name of .prc database }
After declaring the application, you will need to implement at handler for the onstart event, discussed below.
An application needs at least one form. The following is a simple form with a single button:
@form myForm { id = 1000 text = "My Form" x = 0, y = 0, w = 160, h = 160 button myButton { id = 1001 x = 60, y = 80, w = 40, h = 12 text = "My Button" } }
The code above declares a form named myForm
, containing a
button named myButton
.
Both the form and the button use default values for all optional properties, e.g. a full screen non-modal form, a button
with a standard frame and standard font. One thing you may notice is that both objects declared above have names and ids. Each
id must be unique within the application, and must be less than 9000. Each name
must also be unique.
The most interesting parts of the declaration above are the names of the objects. Declaring an app, form, or control actually creates a global variable by that name which can be referenced in code, and is used in implementing handlers.
In order for an application to do anything, it must handle events. An event is handled by declaring an event handler, which is similar to a method - for complete details, see Event Handlers. All applications must implement the app handler onstart, which must load the main form:
handler myApp.onstart() { myForm.load(); }
To make the application more useful, implement handlers for the rest of the
objects. For example, the following code will cause an alert to be displayed
when the myButton
is pressed:
handler myButton.onselect() { alert("Button pressed"); }

OrbC resource langage
The OrbC resource language allows you to easily specify any UI required for your application.
OrbC resource language is embedded directly in OrbC source code. The @ symbol specifies the beginning of a resource block, followed by a single resource declaration (which can contain other declarations). For example, an app declaration could look like this:
@app myApp { creator = "MyAp"; // creator id name = "App Name"; // display name dbname = "AppName-MyAp"; // name of .prc database }
A resource declaration contains a type specifying the resource type being declared. The above example declares an app resource - see the resource table below for all types. Following the type is a name, which can be treated as a global variable in source code. For the example above, a global variable of type UIApp named myApp is created automatically by the compiler. In functions that follow the declaration, you can use this variable to access app properties and methods:
void func() { int colorDepth; // access myApp as a variable colorDepth = myApp.getdepth(); }
Following the name is a block in braces which contains a list of properties (see tables below). The declaration above sets the creator property of the app to "MyAp". Each property is set using the assignment operator (property = value). Properties are separated with semicolons or commas.
This block my also contain other resource declarations. For example, a simple form is declared like this:
@form myForm { id = 1000 text = "My Form" x = 0, y = 0, w = 160, h = 160 button myButton { id = 1001 x = 60, y = 80, w = 40, h = 12 text = "My Button" } }
As you can see, a resource of type "form" is declared named "myForm". Contained within the form is a button named "myButton". Notice that the child declaration does not begin is @, since this only appears on a top level declaration.
Most resources also have an id property. Each id must be unique within the application, and must be < 9000. The id property must be set on each resource that supports it.
Two controls have slightly different rules. First, the graffiti control has no name or id. This is because there can be at most one graffiti shift indicator per form, and they have no runtime properties:
@form myForm { ... graffiti { x = 60, y = 80 } }
Second, a gadget declaration must include the gadget type. For example, to declare a chart gadget such as the one discuss in Creating and Using Gadgets, use code like this. Note that you must declare the Chart type before declaring the resource that uses it.
@form myForm { ... gadget Chart myChart { id = 1011 x = 60, y = 80, w = 40, h = 40 } }
The following resource types are root types and can be declared at the top-level: app, form, resstring, bitmap, and resource.
Creating resizable forms is very easy. First declare your form with the resizable property set to true, then define the form's resize behavior by setting the hresize and vresize properties (generally use stretch for horizontal and vertical). Finally, set the resize behavior for each control on the form. For more details, see UIForm.
The following code declares a form which expands to the size of the screen. The two buttons on the form move as the form resizes to stay in the corners.
@form myForm { id = 1000 text = "My Form" x = 0, y = 0, w = 160, h = 160 resizable = true, vresize = 2, hresize = 2 button topLeftButton { id = 1001 x = 60, y = 80, w = 40, h = 12 hresize = 0, vresize = 0 text = "My Button" } button myButton { id = 1001 x = 60, y = 80, w = 40, h = 12 hresize = 1, vresize = 1 text = "My Button" } }
In order to embed a resource such as a bitmap in your application, you must specify the source of the original bitmap(s). There are two ways to do this. You can either specify a series of BMP file (which only works on the desktop compiler):
@bitmap bmpSplash { id = 4000; image1 = "splash1.bmp"; // b/w image8 = "splash8.bmp"; // 8-bit color imageh1 = "splashh1.bmp"; // b/w high imageh8 = "splashh8.bmp"; // 8-bit color high }
or you can import a resource that already exists in a PRC file:
@bitmap bmpSplash { id = 4000; imageres = "MyResources,Tbmp,1000"; }
The above declaration will import a resource of type 'Tbmp' and id '1000' from a resource database named "MyResources". When compiled on the desktop, the compiler will look for a file named "MyResources.prc". When compiled on the device, the compiler will use the resource database named "MyResources".
The resource string format "<database>,<source type>,<source id>"
is
used for all properties that import from a resource database, such as the smallres and largeres properties
of an icon.
To embed a raw resource, such as a WAVE file, the same mechanism is used. The following block would import a WAVE resource from a Windows .wav file:
@resource { type = "WAVE"; id = 4002; file = "boink.wav"; }
The following would import the same wave from an existing resource database:
@resource { type = "WAVE"; id = 4002; res = "MyResources,WAVE,1234"; }
Finally, you can embed all the resources from a specified resource database using the following:
@resource { res = "RawResources"; }
To make it easier to compile applications on the device, it is possible to create a resource only .prc from which to import all your bitmaps and other resources. If you have both the desktop compiler and the Palm compiler and want to compile on both, it is a good idea to separate your code into two apps - one containing only resources, and one containing all the code. The resource app can be compiled on the desktop and copied to the device, where it can be used as the source for bitmaps and other resources when compiling the main application. Once compiled, only the main application is needed unless you want to compile again. See the Chess Clock sample included with PocketC Architect.
A resource only app is compiled as type 'data' rather than type 'appl', like other applications.
