libgdx crashes when i add dialogs

well i am having a problem

i've started coding my first game with libgdx and i created the menu i am trying to give the about button a function to open a text dialog box

but when i add the code, the game crashes when i run it

can anyone link me to a guide on making a text dialog?

since everything i've found didnt work for me...

the code i have found & used :

new Dialog("Dialog", skin, "dialog") {
   protected void result (Object object) {

   }
}.text("texttexttext").button("Yes", true).button("No", false).key(Keys.ENTER, true)
   .key(Keys.ESCAPE, false).show(stage);

According to your code and the exception:

No com.badlogic.gdx.scenes.scene2d.ui.Window$WindowStyle registered with name: dialog

you need to have a WindowStyle called "dialog" on your skin.json file:

com.badlogic.gdx.scenes.scene2d.ui.Window$WindowStyle:
{
 dialog: { titleFont: <your-font>, titleFontColor: <your-font-color (optional)>, background: <your-background-drawable (optional)>},
}
