<<- Return to webOS Patches


Introduction

The Launcher maintains the last page opened when you return to it. If you most frequently use apps on the first page of the Launcher, you have to swipe back to the first page if the last app you launched was on another page. This patch resets the Launcher to the first page every time it's closed (in readiness for when it's next opened). This works best in combination with the Patch Launcher Reset Scroll on Page Change patch to ensure the page is also always scrolled to the top.

Editing Process

  • SSH in.
  • Remount the filesystem as read/write:
<source lang="bash">

sudo rootfs_open -w

</source>
  • Load launcher-assistant.js in vi:
<source lang="bash">

sudo vi /usr/lib/luna/system/luna-applauncher/app/controllers/launcher-assistant.js

</source>
  • Locate the text 'this.removeLaunchFeedback();' in the onDeactivate method around line 185 (onDeactivate begins at line 171 in webOS 1.3.1, 'this.removeLaunchFeedback();' is the last line of that method):
<source lang="javascript">

/* clean and hide global search */ onDeactivate: function(event) {

this.globalSearchAssistant.deactivate();

this.reorderController.cancel();

if (this.appDialog) { this.appDialog.mojo.close(); }

SystemManagerService.showQuickLaunch(true);

delete this.launchRequest;

this.removeLaunchFeedback(); },

</source>
  • Add the following lines below so that onDeactivate now looks like this:
<source lang="javascript">

/* clean and hide global search */ onDeactivate: function(event) {

this.globalSearchAssistant.deactivate();

this.reorderController.cancel();

if (this.appDialog) { this.appDialog.mojo.close(); }

SystemManagerService.showQuickLaunch(true);

delete this.launchRequest;

this.removeLaunchFeedback();

/* Reset launcher to first page for next time */ $('launcher_root').mojo.setSnapIndex(0, true);

/* * If Bsiegel's 'Reset Scroll Position' patch is installed * then this does what it says on the tin for the first page. */ event.value = 0; /* fudge this because onPageChange expects a * mojo-property-change event but it's actually * getting mojo-event-deactivate. */ this.onPageChange(event);

},

</source>
  • Save the file and quit vi.
  • Remount the filesystem as read only - this should reboot your Pre:
<source lang="bash">

sudo rootfs_open -w

</source>


Patch Process

The patch is not in the webos-internals gitorious repository - if anybody can help with uploading that, it would be much appreciated (it's my first patch!). Until then, you can copy and paste the source below. Visit Applying Patches for info on how to use it. To apply the patch, follow the instructions above, and after remounting the filesystem as read/write, do the following:

  • Apply the patch (In this example, I have the patch file located in my home directory under patches):
<source lang="bash">

cd / sudo patch -p0 --backup-if-mismatch < ~/patches/reset-to-first-page.patch

</source>

This is what you should see if it ran properly: <source lang="text"> patching file /usr/lib/luna/system/luna-applauncher/app/controllers/launcher-assistant.js

</source>
  • Remount the filesystem as read only as described above.
