UAK menu items not showing up in linux

[mekans]

Using the basic MenuWidget from the learn section, i found out that menu widget do not work - i am using i3wm desktop (no effect after clicking), on KDE though i got menu opened in different place on screen, any solution?

[mekans]

does this problem is solved in the ultra engine?

[Josh]

I have not run Ultra Engine on Linux yet. Can you post screenshots of what it does?

[mekans]

sure, i don't have got my KDE desktop (traveling a lot lately) but on my i3 is disapearing (i saw a glimpse of menu that disapeared) while clicking button:

KDE though i can't show you right now but there's a visualisation (when i ll be back home i am going to show screenshot of that)

It was tested on Ubuntu but it's just using the X windowing system and they should all work the same.

What C++ IDE are you using? It looks interesting.

[mekans]

It's CLion by jetbrains
in terms of the application - going to check on ubuntu - gnome (KDE debian works like visualisation on the image).
I don't have got access to ultra engine but if in ultra engine it will work properly i ll consider buying that

[mekans]

I am wondering, mby it's fault of the libraries i set in the cmake

 

set(FLAGS -I/usr/include/freetype2 -I/usr/include/fontconfig -D_ULTRA_APPKIT -I${ULTRAENGINEPATH}/Include)
set(LFLAGS -no-pie -lX11 -lpthread -lXft -lXext -lXrender -lXcursor -ldl)

 

i've installed newest versions of the packages:  libxft-dev libxrender-dev libxcursor-dev libxmu-dev, going to check if i can include something more from UAK packages, and if i can i ll send the results of that

[Josh]

I doubt it. The window positioning is very basic stuff in the X library.

You can try compiling the make file in VSCode if you want to be sure, but I doubt it will make a difference.

[mekans]

Installed KDE + compiled from makefile. Result is like the visualisation i showed earlier

I Guess it's a real problem with UAK in terms of some widgets, Ultra Engine should be tested on Linux distros X11/Wayland on most popular window managers like i3 bspwm and on GNOME/KDE/XFCE and others.
If i find problems like that, i am going to report that in the future.

for now i created poor version of custom menu

#include "UltraEngine.h"

using namespace UltraEngine;

//Declare new style constants
enum CustomMenuStyle
{
    CUSTOM_MENU_DEFAULT = 0
};

//Declare new widget class
class CustomMenuWidget : public Widget

    //Custom members
    bool hover;
    shared_ptr<Panel> contextMenu;
    shared_ptr<Widget> editButton;
    shared_ptr<Widget> removeButton;

        contextMenu = CreatePanel(x, y+25, 100, 40, gui->root);
        contextMenu->Hide();
        editButton = CreateButton("Edit", 0, 0, 100, 20, contextMenu, BUTTON_TOOLBAR);//just for an example, no function
        removeButton = CreateButton("Remove", 0, 20, 100, 20, contextMenu, BUTTON_TOOLBAR);
        ListenEvent(EVENT_WIDGETACTION, editButton, EditbuttonCallback, Self()->As<CustomMenuWidget>());

Thank you @Josh and @Dreikblack for supporting me before, i know my posts were annoying but i finally understand how widgets are created.

[Josh]

Do you happen to know if your distros are using Wayland with an X emulation? If so it would be a bug in that implementation.

[mekans]

I am using X emulation Right now i  do not have access to my vm server - so i can't help you with debugging. After 10.07 i am going to check wayland
