Is there any event system for connecting any widget that renders something in itself eg. tgui::Canvas to render their contents on frame update like for example:

Code (cpp) Select Expand

Canvas->connect("FrameUpdated", drawFunction, std::ref(Canvas));

I have this test function with tgui::EditBox::Ptr as parameter in a separate cpp file

Code (cpp) Select Expand


void test(tgui::EditBox::Ptr Editbox)
{
    Editbox->connect("clicked", []{}); // error
}
And the error produced is:

Code (none) Select Expand


/usr/include/TGUI/Signal.hpp:863:22: error: ‘unsigned int tgui::SignalWidgetBase::connect(std::string, Func&&, const BoundArgs& ...)

Why it does that?

I have a project that I want to test on another Linux pc and I don't have access as a user on that computer to install the dependencies and the single idea that comes to my mind is to link statically, but the only way to obtain thoose libs is to compile sfml from source, but sfml-git package is not required by tgui-git and so on. Do you have an idea on what I can do?

I don't know how to modify the close button of a ChildWindow, cam someone help me?

I try to use a canvas and I don't know if it is possible to set view? if it is, how?

I'm wondering how to get a widget from the gui? I know IIRC there is the function get(string& name). How i can use that (I mean to provide an example)?

I saw there is a function "RemoveWidget" and I don't know how to call it properly. Can someone make an example to see how to use it?

And a side note: someone need to add more tutorials. 

I want to create a list view and at this moment there are no tutorials covering TGUI and the question is: How I connect each individual items of a list view? For example I wrote this code:

Code (cpp) Select Expand


void Editor::Open_dir(tgui::Gui& Editor_gui)
{
    tgui::ListView::Ptr file_listview = tgui::ListView::create();
    std::string path = "Maps";
    for(const std::filesystem::directory_entry& files : std::filesystem::directory_iterator(path))
    {
        file_listview->addItem(files.path().c_str());
        file_listview->connect("pressed", Open_file /*, ...*/);
    }     
}

or is this incorrect?

There is in this library an open file dialog function or something like that? Because i want to create a level editor embedded in my game

I've tried in past to make a gui from scratch before using this library and i wondered: how the library stores function signature?
