    [UAK] Scrolling the widget with MouseWheel or Slider

    in Programming

    Posted

    Hi there,

    I've got custom widget, and i would like to find how to scroll down the data in it.

    Let's get for example the topic you already helped me with, if i get huge amount of the data in this table, how would i scroll down this custom widget?

    I've discovered MouseWheel(const int delta, const int x, const int y), and i know the slider exists, but i got problem with my custom widget.

    Thanks for any help

    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;

protected:

    virtual bool Initialize(const WString& text, const int x, const int y, const int width, const int height, shared_ptr<Widget> parent, const int style)
    {
        bool isInit = Widget::Initialize(text, x, y, width, height, parent, 0);
        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>());
        ListenEvent(EVENT_WIDGETACTION, removeButton, RemoveButtonCallback, Self()->As<CustomMenuWidget>());

        return isInit;
    }
    static bool EditbuttonCallback(const Event& ev, shared_ptr<Object> extra)
    {
        auto listView = extra->As<CustomMenuWidget>();
        listView->contextMenu->Hide();
        Print("edit button run");
        return true;
    }

    static bool RemoveButtonCallback(const Event& ev, shared_ptr<Object> extra)
    {
        auto listView = extra->As<CustomMenuWidget>();
        listView->contextMenu->Hide();
        Print("remove button run");
        return true;
    }
    //Called when the mouse moves if this widget has the focus
    virtual void MouseMove(const int x, const int y) {}

    //Called when the mouse cursor enters the widget bounds
    virtual void MouseEnter(const int x, const int y)
    {
        hover = true;
        Redraw();
    }

    //Called when the mouse cursor leaves the widget bounds
    virtual void MouseLeave(const int x, const int y)
    {
        hover = false;
        Redraw();
    }


    //Called when the mouse button is pressed
    virtual void MouseDown(const MouseButton button, const int x, const int y)
    {

        if (button == MOUSE_LEFT)
        {
            if(contextMenu->hidestate) {
                contextMenu->Show();

            }
            else {
                contextMenu->Hide();

            }
        }
    }

    //Called when the mouse button is released
    virtual void MouseUp(const MouseButton button, const int x, const int y) {}

    //Called when another widget becomes selected
    virtual void LoseFocus() {}

    //Called when mouse double-click occurs
    virtual void DoubleClick(const MouseButton button, const int x, const int y) {}

    //Called when mouse triple-click occurs
    virtual void TripleClick(const MouseButton button, const int x, const int y) {}

    //Called when widget is selected
    virtual void GainFocus() {}

    //Called when key is pressed
    virtual void KeyDown(const UltraEngine::KeyCode key) {}

    //Called when key is released
    virtual void KeyUp(const UltraEngine::KeyCode key) {}

    //Called for each keydown event
    virtual void KeyChar(const int keychar) {}

    //Called when mouse wheel turns and mouse is hovered over this widget
    virtual void MouseWheel(const int delta, const int x, const int y) {}

    //Called each time the widget is redrawn
    virtual void Draw(const int x, const int y, const int width, const int height)
    {
        blocks.clear();
        Vec4 color = Vec4(0.255f, 0.10f, 0.10f, 1);
        if (hover) color = Vec4(0.255f, 0.255f, 0.255f, 1);

        //Background rectangle
        AddBlock(iVec2(0), this->size, color);

        //Foreground text
        AddBlock(text, iVec2(0), this->size, Vec4(1), TEXT_CENTER | TEXT_MIDDLE);
    }
public:

    //Constructor
    CustomMenuWidget() : hover(false)
    {}

    friend shared_ptr<Widget> CreateCustomMenuWidget(const WString&, const int, const int, const int, const int, shared_ptr<Widget>, const CustomMenuStyle);
};

//Create function
shared_ptr<Widget> CreateCustomMenuWidget(const WString& text, const int x, const int y, const int width, const int height, shared_ptr<Widget> parent, const CustomMenuStyle style)
{
    auto widget = std::make_shared<CustomMenuWidget>();
    widget->Initialize(text, x, y, width, height, parent, style);
    return widget;
}

     

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

    UAK menu items not showing up in linux

    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

    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

    Ultra App Kit - table

    i adjusted this solution in some way, but i need now table like listview in c#. It should be columns, headers and rows that could be selected. in a picture we can see that Cell0,0 1.0 and 2.0 are separate cells with data - i need them as a full row that are related to one object and displaying this object data.

    Tbh i tried to build a custom widget with rows and other stuff but it's too hard for me
