This patch moves the formerly hard-wired drag-and-drop handling
to the configuration level by introducing the actions "drag" and "drop".
To aid the robust handling of release events matching their
corresponding press events, the patch refines the policy-matching of the
current combination of keys against the hierarchy of <press> and
<release> nodes. If no policy for a concrete combination exists, a
release event also considers the policy of its matching <press> node.
This way, the regular drag-and-drop rules can be expressed as
<press key="BTN_LEFT" action="drag">
<release key="BTN_LEFT" action="drop"/>
</press>
This also works when releasing BTN_LEFT while pressing additional keys,
for which no policy exists.
With this change, the layouter supports the matching of multiple key
sequences instead of only one, thereby supporting multiple actions at
once and allowing for decoupling different user interactions in the
configuration.
Issue #5403
This directory contains ports of 3rd-party libraries to Genode. Usage ----- The tool './tool/ports/prepare_port' in the toplevel directory automates the task of downloading and preparing the 3rd-party source codes. One can select individual ports that have to be prepared by specifying their base names (without the version number) as command-line argument. For example, the following command prepares both the C library and the Freetype library: ! ./tool/ports/prepare_port libc freetype To compile and link against 3rd-party libraries of the 'libports' repository, you have to include the repository into the build process by appending it to the 'REPOSITORIES' declaration of your '<build-dir>/etc/build.conf' file. Under the hood -------------- For each library, there is a file contained in the 'libports/ports/' subdirectory. The file is named after the library and contains the library-specific rules for downloading the source code and installing header files. How does 'libports' relate to the other repositories? ----------------------------------------------------- Most libraries hosted in the 'libports' repository expect a complete C library, which is provided via the 'libc' port. The libc, in turn, depends on the 'os' repository for its back end.
