QProxyModel/SortModel display items without children ?

Dariusz

Hey

Say I have a item model with this hierarchy:

>item
    >item2
       >item3  
          >item4

Which model should I use to display it as

item
item2
item3  
item4

So no children, all linearly top to bottom.

As well as then display only ones matching specific string...
Would a QSortFilterProxyModel work for both of my needs or do I have to daisy chain 2 together? QProxyModel + SortFilter?

Regards
Dariusz

How on earth do I get it

Open a developer command prompt with cmake and git and run:
(This is for Windows on MSVC, for MinGW replace NMake with MinGW. for linux/mac just remove -G"NMake Makefiles")

git clone https://invent.kde.org/frameworks/extra-cmake-modules.git
cd extra-cmake-modules
mkdir build
cd build
cmake -G"NMake Makefiles" -DCMAKE_BUILD_TYPE=RELEASE -DCMAKE_INSTALL_PREFIX="../../KDEAPI" ../
cmake --build . --target install
cd ../../
git clone https://invent.kde.org/frameworks/kitemmodels.git
cd kitemmodels
mkdir build
cd build
cmake -G"NMake Makefiles" -DCMAKE_BUILD_TYPE=RELEASE -DCMAKE_PREFIX_PATH="../../KDEAPI" -DCMAKE_INSTALL_PREFIX="../../KDEAPI" ../
cmake --build . --target install
cmake -G"NMake Makefiles" -DCMAKE_BUILD_TYPE=DEBUG -DCMAKE_PREFIX_PATH="../../KDEAPI" -DCMAKE_INSTALL_PREFIX="../../KDEAPI" ../
cmake --build . --target install
cd ../../
rmdir extra-cmake-modules /s /q
rmdir kitemmodels /s /q

Now just add the path to the newly created KDEAPI folder to the CMAKE_PREFIX_PATH of your project in the project configuration

KDescendantsProxyModel from KItemModels https://api.kde.org/frameworks/kitemmodels/html/classKDescendantsProxyModel.html

do I have to daisy chain 2 together? QProxyModel + SortFilter?

Chain away!

@VRonin WOaaa KDescendantsProxyModel looks epic but... How on earth do I get it O.O

@Dariusz

What do you use as build system? (CMake/qmake/qbs/etc.)
What OS are you on?

Dariusz

@VRonin Hey
Cmake/ all platforms.

I think I'm good, I can just "borrow" the 2 classes from > https://invent.kde.org/frameworks/kitemmodels/-/tree/master/src/core o.O
EPIC !
I need to dig more in to that website, thats awesome o.o

@VRonin Awesome thanks! I was able tho to just grab the 2 files and use them directly so yay!

This tree model is epic. It does 90% of what I wanted ! Now I just gotta figure out how to hide parent/groups, so I only see items, but that should be fine, super awesome, thanks!

Edit1. using sort filter model later to decide if I want to show parents/etc worked just fine, yay!
