hi forum
i would appreciate a possibility in Dolphin to enable autoplay of audio- or videofiles when mouse hovering over it, instead of open an external mediaplayer everytime.
Remember that Mate used to have that option, as far as i know KDE does not, or not entirely (only in certain open file dialogs).

what i found is:
https://www.kubuntuforums.net/showthread.php?63185-Auto-preview-audio-and-video-files-in-the-Dolphin-and-Konqueror
but in the process of compiling Dolphin with a tuned tooltipmanager it got stucked: missing a lot of KF5 -tools !?
>>according to google KDE-Frameworks is missed and installable only by a PPA or compiling should be with src-build....

I'm not sure about all that and wether this whole error-prone project is worth the candle?

Has anyone another idea or a clue? Any future perspectives relating to enabling of that feature?

KDE Forums Brainstorm - Dolphin Video audio play hovering the file: viewtopic.php?f=83&t=92269

Meanwhile

There could be alternative versions of the KDE applications - a user can install them to the home or to the /opt/.



The drill, at here, with the Dolphin is:

1) Get the sources - using distribution sources (pkgbuild)
2) Edit the sources - adding the option to play on mouse over and put the konsole to the left/right/top/bottom.
3) Build - building an Arch Dolphin package.
4) Install - Installing the package.
5) Use - adding the alternative Dolphin to the KDE Menu




To build an alternative version of the Dolphin:

Lacking a lot! Is it a whole package thats missing here? KDE-Framework?

As the Neon is using the Debian packaging system then the easiest way to get the build dependencies should be with the:

Code: Select all

apt-get build-dep

command. Dolphin:

Code: Select all

sudo apt-get build-dep dolphin

More from Debian Building Tutorial: https://wiki.debian.org/BuildingTutorial --> https://wiki.debian.org/BuildingTutoria ... pendencies

If you enable dolphin's "Informations" sidebar though (in the menu "View"->Sidebars), you can play audio and video files by clicking on the small play button in the preview:


That's not exactly on mouse hover, but at least saves you from opening an external application...
And it's built-in, no need to patch dolphin and build it yourself.

@Rog131
thanks again!

but how to build and install to /opt/KF5 with the DEBIAN-building commands (debuild -b -uc -us)?
What is the equivalent to -DCMAKE_INSTALL_PREFIX=/opt/KF5 -DCMAKE_PREFIX_PATH=/opt/KF5 ??

@wolfi323
thanks for your hint. This is helpful and i will make do with it if compiling doesn't work.
But in general i'm curious how to in linux and in different linux distros and last but not least i love the feature of autoplay at mouseover.
I think its very handy when working with sound collections.

IF

If you want to wrap the alternative version of the Dolphin to the Debian package you will need to:

- Rename your package - there can be only one 'dolphin' named package installed.



- write a 'debian/rules' file with support to the cmake options.

There are many Debian packaging guides. Picking one: Debian New Maintainers' Guide - https://www.debian.org/doc/manuals/maint-guide/

BUT

You could use the 'apt-get build-dep' to install the Debian/Ubuntu/Neon/... build dependencies and then compile/install your alternative version with generic commands:

Code: Select all

$ mkdir -p builddir

$ cd builddir && cmake .. \
    -DCMAKE_BUILD_TYPE=Release \
    -DCMAKE_PREFIX_PATH=/opt/KF5 \
    -DCMAKE_INSTALL_PREFIX=/opt/KF5 \
    -DLIB_INSTALL_DIR=lib \
    -DKDE_INSTALL_USE_QT_SYS_PATHS=off \
    -DBUILD_TESTING=OFF

$ make

$ sudo make install

Example:

Unpacking the dolphin-16.08.2.tar.xz and (making wanted editions) cd to /dolphin-16.08.2/

Code: Select all

[rog131@archfox dolphin-16.08.2]$ mkdir -p builddir         
[rog131@archfox dolphin-16.08.2]$ cd builddir && cmake .. \
>     -DCMAKE_BUILD_TYPE=Release \
>     -DCMAKE_PREFIX_PATH=/opt/KF5 \
>     -DCMAKE_INSTALL_PREFIX=/opt/KF5 \
>     -DLIB_INSTALL_DIR=lib \
>     -DKDE_INSTALL_USE_QT_SYS_PATHS=off \
>     -DBUILD_TESTING=OFF

@ Rog132
you made my day!
and it works nearly flawlessly
Thanks a bundle man! You really want to share your knowledge and you know how to with best effort!

Since i moved to Arch Linux Plasma, i'd like to run the process of building dolphin kf5+ again! But i don't know what are the dependencies in Arch and wether its possible with Arch Linux Plasma at all?
Maybe meanwhile someone knows an new alternate possibility for mouse-over?

With the Arch Linux it is a bit easier: Creating packages - https://wiki.archlinux.org/index.php/creating_packages

-> You will need the 'base-devel'.


An example:

Browsing to the https://www.archlinux.org/packages/extr ... 4/dolphin/ -> https://git.archlinux.org/svntogit/pack ... es/dolphin and downloading the PKGBUILD.

Executing:

Code: Select all

makepkg

to get source and the make dependencies - output:

==> Making package: dolphin 17.04.2-1 (ma 19.6.2017 21.20.43 +0300)
==> Checking runtime dependencies...
==> Checking buildtime dependencies...

==> Validating source files with sha256sums...

==> Verifying source file signatures with gpg...
dolphin-17.04.2.tar.xz ... FAILED (unknown public key 3A6A4DB839EAA6D7)
==> ERROR: One or more PGP signatures could not be verified!

When you are building for yourself you could bypass the error.

Editing the PKGBUILD:

Changing the:

Code: Select all

pkgname=dolphin

to

Code: Select all

pkgname=dolphin-yourname

My name is 'dolphin-kf5git'

Note !
Building an alternative version and having both 'dolphin' and ' dolphin-yourname' installed.

Unpacking the dolphin-17.04.2.tar.xz to the /src/dolphin-yourname-17.04.2 and making the /src/build/.



Editing the /src/dolphin-17.04.2/src/views/tooltips/tooltipmanager.cpp and adding other Dolphin extras...

After edits executing:

Code: Select all

makepkg -e

Code: Select all

man makepkg

       -e, --noextract
           Do not extract source files or run the prepare() function (if present); use
           whatever source already exists in the $srcdir/ directory. This is handy if you
           want to go into $srcdir/ and manually patch or tweak code, then make a package
           out of the result.

As result there should be dolphin-yourname-17.04.2-1-x86_64.pkg.tar.xz

Installing the alternate Dolphin with command:

Code: Select all

sudo pacman -U dolphin-yourname-17.04.2-1-x86_64.pkg.tar.xz

Code: Select all

man pacman

       -U, --upgrade
           Upgrade or add package(s) to the system and install the required dependencies
           from sync repositories. Either a URL or file path can be specified...

The alternate dolphin can be launched with command:

Code: Select all

export LD_LIBRARY_PATH=/opt/KF5/lib; /opt/KF5/bin/dolphin

or/and added to the KDE menu.


Testing ...

seems to work.

thanks again for your answer Rog131,

forgive me my ignorance but i'm a bit puzzled with tho whole process, though i've been through it in the past.
The order you listed once was:
1) Get the sources - using distribution sources (pkgbuild) --->> I downloaded: dolphin 17.04.2-1 pkg and PKGBUILD and also dolphin source: https://github.com/KDE/dolphin
2) Edit the sources - adding the option to play on mouse over and put the konsole to the left/right/top/bottom.--->> Sorry I forgot how to do that! In https://www.kubuntuforums.net/showthread.php?t=63185 i don't see the wood for the trees... Could you please give me a hint?
3) Build - building an Arch Dolphin package.
4) Install - Installing the package.
5) Use - adding the alternative Dolphin to the KDE Menu -->those last 3 steps should be clear
Thanks

With the Dolphin 17.04.2 I have been using patch - tooltipmanager.diff:

It will execute the /usr/local/bin/MouseOverAction.sh when the mouse is over the icon and kill it when the
mouse is moving off.

Setting up the preview with the Dolphin: https://www.kubuntuforums.net/showthrea ... post340393

thank you Rog131 !!
i'm looking forward to apply it.

Sorry Rog131,
i'm feeling really stupid ...but... i don't get it.

If i understood you right the approach is as follows:
1. downloading the PKGBUILD of dolphin 17.04.2-1
2.

Code: Select all

makepkg

---> bypassing the error 'unknown public key 3A6A4DB839EAA6D7' by:

Code: Select all

gpg --recv-key 3A6A4DB839EAA6D7
gpg --lsign 3A6A4DB839EAA6D7

otherwise makepkg aborts
3. then: Editing the PKGBUILD

Code: Select all

pkgname=dolphin-myname

and

Code: Select all

build() {
  cd build
  cmake ../$pkgname-$pkgver \
    -DCMAKE_BUILD_TYPE=Release \
    -DCMAKE_PREFIX_PATH=/opt/KF5 \
    -DCMAKE_INSTALL_PREFIX=/opt/KF5 \
    -DLIB_INSTALL_DIR=lib \
    -DKDE_INSTALL_USE_QT_SYS_PATHS=off \
    -DBUILD_TESTING=OFF
  make
}

4. Unpacking the dolphin-17.04.2.tar.xz to the /src/dolphin-myname-17.04.2 and making the /src/build/
---> isn't makepkg missing before this?
So in the end there would be these two packages: dolphin-17.04.2 and dolphin-myname-17.04.2 but i don't quite get that kind of nesting: which dolphin into what /src/..?
and what is meant by "making the /src/build/"? Simply creating that directory?
5. Editing the /src/dolphin-17.04.2/src/views/tooltips/tooltipmanager.cpp and adding other Dolphin extras
6.

Code: Select all

makepkg -e

7. Installing the alternate Dolphin with command:

Code: Select all

sudo pacman -U dolphin-myname-17.04.2-1-x86_64.pkg.tar.xz

Please correct me where i'm wrong and thanks for your patience

I'm simply letting the 'makepkg' to die. I only want the source and the dependencies.

The /usr/bin/makepkg is part of the package 'pacman'.


At here:

1) Get the source and the build dependencies - i.e:

Code: Select all

makepkg

2) Edit the source and the PKGBUILD (package name and the installation path)

3) Build the package from the edited source:

Code: Select all

makepkg -e

Example:

At the same directory as the PKGBUILD file:

1) Get the source and make needed directories:

Code: Select all

makepkg
mkdir -p ./src/build
mkdir -p ./src/dolphin-example-17.04.2
tar -xf dolphin-17.04.2.tar.xz -C ./src/dolphin-example-17.04.2 --strip-components=1

2) Changing directory to ./src/dolphin-example-17.04.2/. Patching. Changing directory back to the same directory as the PKGBUILD file:

Code: Select all

cd ./src/dolphin-example-17.04.2/
patch -p1 -i '../../tooltipmanager.diff'
cd ../../

Editing the PKGBUILD:

Code: Select all

kwrite PKGBUILD

3) Build the package from the edited source with the edited PKGBUILD:

Code: Select all

makepkg -e

Note !
At this I have been using the cli. You could use KDE tools - Ark etc.
