Too many buttons in plugin

[whurlston]

Is there a way to limit the number of buttons displayed in a plugin's menu? If not, is there a way to refresh the call to getButtonList()? I've got too many menu buttons and they get rendered off the screen. I think I have a method of resolving this but I wanted to make sure I wasn't overcomplicating it.

Unfortunately no, there is nothing built in to handle this.

No problem, as I said, I think I found a workaround. Thanks for the reply.

One more quick question, is there a way to get the selected button? I though I saw a method for this but I can't find it now.

Again, unfortunately no. The BaseButtonListUiTask plugins arent aware of which is highlighted until the use clicks it, at which time handleCommand() method is executed.

No problem, I'll figure something out.

I figured it out. To wrap up this thread and in case anyone else wants to do this, there may be an easier way but this worked for me:

Add the following global variables to your plugin:

Code:

List<UiButton> DisplayedButtons = new List<UiButton>();
List<System.Drawing.RectangleF> ButtonPositions = new List<System.Drawing.RectangleF>();
private int maxButtons = 10; // The number of buttons you want to display;
private int lastActiveButton = 0;

Then for your getRenderList():

Code:

public override ArrayList GetRenderList()
  {
   ArrayList rList = base.GetRenderList();
   ArrayList newRenderList = new ArrayList();
   ArrayList bList = buttonList;
   bool activeButtonFound = false;
   for (int x = 0; x < buttonList.Count; x++)
   {
    UiButton button = (UiButton)buttonList[x];
    if (button.isActive() || button.buttonState == UiButton.State.Activating)
    {
     if (!DisplayedButtons.Contains(button))
     {
      DisplayedButtons = new List<UiButton>();
      if (x == 0 || lastActiveButton == 0 || lastActiveButton < x)
      {
       if (x > maxButtons - 1)
       {
        for (int y = x - (maxButtons - 1); y < (x + 1); y++)
         DisplayedButtons.Add((UiButton)buttonList[y]);
       }
       else for (int y = 0; y < maxButtons; y++) DisplayedButtons.Add((UiButton)buttonList[y]);
      }
      else
      {
       if (x == buttonList.Count - 1)
       {
        for (int y = buttonList.Count - (maxButtons + 1); y < buttonList.Count; y++)
         DisplayedButtons.Add((UiButton)buttonList[y]);
       }
       else for (int y = x; y < x + maxButtons; y++) DisplayedButtons.Add((UiButton)buttonList[y]);
      }
     }
     activeButtonFound = true;
     lastActiveButton = x;
     break;
    }
   }
   if (!activeButtonFound && DisplayedButtons.Count == 0)
    for (int x = 0; x < maxButtons; x++) DisplayedButtons.Add((UiButton)buttonList[x]);
   foreach (GBPVRUiElement elem in rList)
   {
    if (!elem.name.StartsWith("button-"))
    {
     newRenderList.Add(elem);
    }
    else
    {
     ButtonPositions.Add(elem.rect);
     for (int x = 0; x < DisplayedButtons.Count; x++)
     {
      if (elem.name.StartsWith(string.Format("button-{0}", DisplayedButtons[x].name)))
      {
       elem.SetRect(ButtonPositions[x]);
       newRenderList.Add(elem);
       break;
      }
     }
    }
   }
   return newRenderList;
  }

Just a warning. The above code only works for keyboard and remote commands. Mouse clicking a button could result in an undisplayed button being activated.
