|
|---|
| 35 | <p> Qt is a multiplatform GUI toolkit, so almost the entire API is the
|
|---|
| 36 | same on all platforms and window systems. If you wish to use
|
|---|
| 37 | platform-specific features, and still maintain a platform-independent
|
|---|
| 38 | source tree, you should protect the platform-specific code using the
|
|---|
| 39 | appropriate <tt>#ifdef</tt> statements (see below).

|
|---|
| 76 | </h3>
|
|---|
| 77 | <a name="2-1"></a><p> Executables compiled with Microsoft Visual Studio 2005 require
|
|---|
| 78 | a manifest file that points to the C and C++ runtime libraries that
|
|---|
| 79 | Qt and the application itself depend on. The manifest file is
|
|---|
| 80 | automatically generated for you, but it always needs to be located
|
|---|
| 81 | in the same directory as the application executable.
|
|---|
| 82 | <p> It is important to remember to deploy the manifest file when
|
|---|
| 83 | deploying an application.
|
|---|
| 84 | <p> <b>Note:</b>
|
|---|
| 85 | If you don't want to deploy your application with the .manifest file,
|
|---|
| 86 | you can embed the manifest in the executable as a resource with the
|
|---|
| 87 | <tt>mt</tt> command (distributed with Visual Studio 2005).
|
|---|
| 88 | <p> If you have further problems, please see the MSDN document,
