Hey,

I'm trying to use the listbox signals but everytime I try to connect a signal to the listbox instance, I get an "Unhandled exception at 0x011611FA in BLAH.exe: 0xC0000005: Access violation reading location 0x000000A4."

When I break, it seems to be stopped in the signalbasewidget.hpp file at the below location

        template <typename Func, typename... Args>
        unsigned int connect(const std::string& signalNames, Func func, Args... args)
        {

            {
                if (m_signals.find(toLower(signalName)) != m_signals.end())     //<----------STOPS HERE STOPS HERE STOPS HERE
                {
                    try {
                        m_signals[toLower(signalName)]->connect(m_lastId, func, args...);
                        m_lastId++;

                        throw Exception{e.what() + (" The parameters are not valid for the '" + signalName + "' signal.")};
                    }
                }


I've tried ItemSelected, MouseEntered, MousePressed and all the same result. See below a full working exampe of what I am trying to do. Any ideas on what I am doing wrong here?

awesome - works a treat. Thank you.

Is it possible to set the position of the text on a button? I have the text size small and I wanted it to be in the top left corner of the button.

Ok no problem. So to clarify I was going to suggest two new features.

1:- The horizontal scroll-bar on a listbox if the item is longer than the width of the listbox.
2:- Field formatting of items (in my case string items) on a per line basis.

i.e. I want to displaying something like below. So there is a delimiter that can seperate the items into fields/columns and the field/columns width or position can be defined. I know this is probably alot of work but I just thought to suggest it.

ListBoxCol1Row1 ListBoxCol2Row1 ListBoxCol3Row1
ListBoxCol1Row2 ListBoxCol2Row2 ListBoxCol3Row2



No worries mate - thanks for checking. Good luck with uni.

Should i post this new feature request somewhere so you can keep track of it when you next look at doing a new version?

Hi Texus,

Is it possible to add a horizontal scrollbar to a listbox? I have some string items that are too long to display on a single line and I would like users to be able to scroll horizontally so they are see the end of each line.

Or is there a way to display a single item over multiple lines?

No worries at all and thanks for the help once again.

But I'll add a setAutoScroll function in v0.7-alpha2, I'll probably even make it scroll by default so that you don't even have to call anything.

Yeah this would be a great idea - perhaps with a method to disable auto-scrolling as well?

Hey Texus,

Just wondering if you had a chance to look at this question ? I know you are busy so no worries if you need more time etc.

Hi Texus,

In a chatbox, when I add a new line, if it is larger than the size of the chatbox, it automatically scrolls down.
However in a listbox, I do not get the same behaviour when I add a new item. I get the scrollbar fine and I can manually scroll up and down which is great.
Basically I want to use the listbox functionality of being able to select each line and call functions when a particular line is clicked. However I also want the chatbox functionality of autoscrolling when a new item is added.

Is there any flag on a listbox to enable this same behaviour?

Hi Texus,

I cannot seem to locate a setTextSize method for a listbox - (i.e. chatbox has such a method so I was looking for something similiar).

I see there is a setItemHeight method but in the documents is says "This size is always a little big greater than the text size."

So is this what actually determines the text size in a listbox?

Ok thanks. I'm at work now (based in New Zealand) so I'll try that when I get home.

To confirm the below

I is supposed to be:

Code (cpp) Select Expand

tgui::Button::Ptr button = theme->load("CustomButtonRomeHI");

without the "Button." in front of it. But I still don't get how you could get an exception WidgetConverer. That object is only created once the button was fully loaded.

Ok so in the main example, indeed it worked when I dropped the preceding "Button.".
Then I went back to my class but still got same error.
After a bit more tinkering, I realized that I had only updated the Button.CustomButtonRomeHI section with the Part(56,  0,  48, 64);

All of the others were as below. So the CustomButtonRomeHI got created fine, but none of the others. Obviously Part is mandatory now then.

Code (cpp) Select Expand


Button.CustomButtonRomeLI {
    NormalImage  : "..\images\icons\romeNationIcon_v3.png" (  104,  0,  48, 64);
    HoverImage   : "..\images\icons\romeNationIcon_v3.png" (  104,  65,  48, 64);
    DownImage    : "..\images\icons\romeNationIcon_v3.png" (  104,  129,  48, 64);
    TextColorNormal : rgb(190, 190, 190);
    TextColorHover  : rgb(250, 250, 250);
    TextColorDown   : rgb(250, 250, 250);
}


For how I got an exception in WidgetConverer then I'm not sure. I will put back my original file and re-test when I get the pdb file. Likely tonight (your tomorrow) though.

Thanks for all of your help and sorry for all of the questions with v0.7!

Thanks. I downloaded the pre-compiled file TGUI-0.7-alpha1 Visual C++12 (2013) - 32bit.zip

Do you know how/where I can get a tgui-d.pdb? I can try to debug further but now I keep getting tgui-d.pdb not loaded.....unsure how it was working earlier.

Also I tried using the Black.png as well but no joy

i.e.

Code (cpp) Select Expand


Button.CustomButtonRomeHI {
    NormalImage  : "Black.png" Part(  56,  0,  48, 64);
    HoverImage   : "Black.png" Part(  56,  65,  48, 64);
    DownImage    : "Black.png" Part(  56,  129,  48, 64);
    TextColorNormal : rgb(190, 190, 190);
    TextColorHover  : rgb(250, 250, 250);
    TextColorDown   : rgb(250, 250, 250);
}



I also tried coping the entire Button section into the new section as well but same thing.

i.e. this is the exact same as the Button section which works.

Code (cpp) Select Expand


Button.CustomButtonRomeHI {
    NormalImage     : "Black.png" Part( 0, 64, 45, 50) Middle(10, 0, 25, 50);
    HoverImage      : "Black.png" Part(45, 64, 45, 50) Middle(10, 0, 25, 50);
    DownImage       : "Black.png" Part(90, 64, 45, 50) Middle(10, 0, 25, 50);
    TextColorNormal : rgb(190, 190, 190);
    TextColorHover  : rgb(250, 250, 250);
    TextColorDown   : rgb(250, 250, 250);
}


Hi Texus,

Ok I tried the below which is pretty much as per one of tutorials and example codes.

Here is my new widget config file - rest of the txt file is unchanged and i did not change the Button section at all. I thought maybe it couldn't find the png as it was in a different folder, so I copied it into the same folder as the rome.txt file and removed the ..\..\ lines but same thing.

Note when I change to just below then it works fine

Sorry for all of the v0.7 questions lately - I really do appreciate your help.

In v0.69 I had a button conf like below

Code (cpp) Select Expand



Button:
    NormalImage  = "../../images/icons/romeNationIcon_v2.png" (  56,  0,  48, 64)
    HoverImage   = "../../images/icons/romeNationIcon_v2.png" (  56,  65,  48, 64)
    DownImage    = "../../images/icons/romeNationIcon_v2.png" (  56,  129,  48, 64)
   
    TextColor          = (200, 200, 200)
    SeparateHoverImage = true


So in v0.7, I created a new section as below

Code (cpp) Select Expand



CustomButtonRomeAR {
    NormalImage  : "../../images/icons/romeNationIcon_v2.png" (  248,  0,  48, 64);
    HoverImage   : "../../images/icons/romeNationIcon_v2.png" (  248,  65,  48, 64);
    DownImage    : "../../images/icons/romeNationIcon_v2.png" (  248,  129,  48, 64);
    TextColorNormal : rgb(190, 190, 190);
    TextColorHover  : rgb(250, 250, 250);
    TextColorDown   : rgb(250, 250, 250);
}


however whenever I try to create a button with this section, it throws an error

Code (cpp) Select Expand


tgui::Button::Ptr button = theme->load(passed_themeSection);


where passed_themeSection = "CustomButtonRomeHI"

I am assuming I've gotten the syntax incorrect here?

Sorry error is:

"tgui::Exception at memory location 0x0014CF08."

It breaks into WidgetConverter.hpp at line 65

Thanks again.

So I am trying to add radio buttons using the black.txt file.
I've setup the theme as per the themes tutorial. (https://tgui.eu/tutorials/v0.7/using-themes/)

I have been able to create panels and labels without issue, but the radiobutton throws an error. I am using visual studio 2013 and I don't have a tgui.pdb so when it fails, I don't see the exact source line it fails. I get a Expression: pFirstBlock ==pHead error in the dbgheap.c.

My function is below and it fails at the "tgui::RadioButton::Ptr radioButton = theme->load("RadioButton");" line.

Code (cpp) Select Expand


void Test::setupRadioButton(sf::Vector2i pos, sf::Vector2i size, sf::Color passed_colour, vector<string> stringList, tgui::Container::Ptr container)
{
int yposIncrementer = 0;

for (int i = 0; i < stringList.size(); i++)
{
if (container != NULL && container->get(stringList[i]) == NULL)
{
tgui::RadioButton::Ptr radioButton = theme->load("RadioButton");
radioButton->setPosition(pos.x, pos.y + yposIncrementer);
radioButton->setSize(size.x, size.y);
radioButton->getRenderer()->setTextColor(passed_colour);
if (stringList.size() > 0)
{
radioButton->setText(stringList[i]);
}
container->add(radioButton, stringList[i]);
yposIncrementer += size.y;
}
}
}


Here is a full working example. The drawLoadingScreen method which uses a panel with labels works fine. However the drawMainMenu fails when I try to add a radiobutton. Am I doing something wrong here?

awesome - thank you. Worked a treat.

So what I am trying to do here is first setup a main menu panel where I had a background. I then want to put various widgets into the panel such as labels, radio buttons etc.

So I can create the panel without any issues.
Then the draw menu screen, I have a setupLabel function where one of the parameters to pass in is the tgui::Container::Ptr.
Now I use the gui.get to retrieve the panel but this returns type widget::ptr and so i get a compile error. I tried calling getparent but obviously this just returns gui.

Is there any to search the gui for the widget name and get the container back? Note right now it is a panel, but I also want to use setupLabel for say child windows or other container types.

Here is a full working example of what I'm trying to do.

See the drawLoadingScreenGUI() method.
It calls initMainMenuPanel() which adds a panel to gui. I now want to call setupLabel and pass in a ptr to the panel.
As you can see I'm calling gui.get("mainPanel") which does return the widget::ptr but I cannot add a label to a widget, I assume I need a container type?

Ah ok cool. I'll let you know how that goes.

BTW, I really really like the new way of adding widgets to the gui or a container. Also I find the new get method to be able to retrieve the widget pointer really, really useful.

EDIT:- both of the recommendations above worked a treat.

Hey,

I was trying to set the background texture for a panel.

I tried the line below, but there doesn't appear to be a setbackgroundtexture method. I don't see any panel renderer class? Is this coming in a later version? Any recommendations to get around this currently?

void drawEngine::setupPanel(sf::Vector2i pos, sf::Vector2i size, sf::Color passed_backGroundColour, string passed_panelName, sf::Texture *passed_texture)
{

if (gui.get(passed_panelName) == NULL)
{
tgui::Panel::Ptr mainMenuPanel = theme->load(themeConfFile);
mainMenuPanel->setPosition(pos.x, pos.y);
mainMenuPanel->setSize(size.x, size.y);
mainMenuPanel->setBackgroundColor(passed_backGroundColour);
if (passed_texture != NULL)
{
mainMenuPanel->getRenderer()->setBackgroundTexture(passed_texture);
}
}
}


Ok, so in the connect function, the signal "pressed" is actually not a user-definable signal. It is a signal that is part of the widget constructor,

i.e. in button.cpp I see the line below in the button constructor.

Code (cpp) Select Expand



addSignal<sf::String>("Pressed");


For some reason I thought the first parameter of the connect function could be whatever we wanted, i.e. like the setCallbackId method.

Re-reading the class documentation of v0.7, I now see the signal section, so ok this makes more sense now.

https://tgui.eu/documentation/v0.7/classtgui_1_1Button.html

"Detailed Description

Button widget.

Signals:

    Pressed (the button was pressed)
        Optional parameter sf::String: Caption of the button
        Uses Callback member 'text'
    Inherited signals from ClickableWidget"

One question, what is difference between the button pressed and the clickableWidget clicked signal?

Hi,

Ok so I tried v0.7 for the first time today. I put in my v0.69 code and had zillions of compile errors as alot has changed.

Most are pretty easy to understand/modify, i.e. there is the renderer class and also there is no load method but we need to use the theme->load etc

However one thing that I am confused about is the change to signals.

In v0.69 there was the below in order to know when a button had been pressed with the left mouse button.

Code (cpp) Select Expand


    button->bindCallback(tgui::Button::LeftMouseClicked);
    button->setCallbackId(1);


Now in v0.70, I get a compile error that tgui::Button::LeftMouseClicked does not exist.

I see in the v0.7 example code that it uses the connect method.

Code (cpp) Select Expand


    // Call the login function when the button is pressed
    button->connect("pressed", login, editBoxUsername, editBoxPassword);


Ok seems simple enough but what I do not get there is how does the button widget know that this function gets triggered when the left mouse button is clicked. what if I wanted to do something if the right mouse button is clicked or if the middle button etc ?

I am sure I am missing something obvious here but I just don't quite get it.
