Is there a way to get live feedback from a MultilineEditText gui?

Bool myDialog::CreateLayout(void)  
{  
  
  GroupBegin(0,BFH_LEFT,2,0,"MyTextGroup",0);  
  {                  
      AddEditText(1001, BFH_SCALEFIT,400,15,0);            //A single line text box gui  
      AddMultiLineEditText(1002, BFH_SCALEFIT,400,150,0);  //A multi line textbox gui  
  }  
  GroupEnd();  
  
  return TRUE;  
}  
  
  
  
Bool myDialog::Command(LONG id,const BaseContainer &msg)  
{  
  
  String textbox;  this->GetString (1001, textbox);  
  GePrint(textbox);   //This prints live while typing text into the gui--->Yay!!  
  
  
  String multi_textbox;  this->GetString (1002, multi_textbox);  
  GePrint(multi_textbox); // <--- This does NOT print live while typing like the textbox gui  
                          //      It only prints when the user selects another part of the dialog.  Boo!! :-(  
  
  
  
  return TRUE;  
}

I think you must catch the text entry in the Message() method. I would think it works the same as a regular EditText for which you should find some examples here maybe but I'm having trouble finding them or any that I may have tried in the past. If I find some code then will post it asap.

Hi,

You can overload Message() and capture BFM_GETCURSORINFO message:

virtual LONG Message(const BaseContainer &msg,BaseContainer &result)
{
    GePrint("Message()");
    GePrint(LongToString(msg.GetId()));
  
    if (msg.GetId()==BFM_GETCURSORINFO)
    {
        String text;
        if(GetString(1002, text))
            GePrint(text);
    }
  
    return GeDialog::Message(msg,result);
}

BFM_GETCURSORINFO wasn't designed for this but it's the only message sent when text is typed inside the MultilineEditText.

OK. Thanks.
Like you said. While the cursor is inside of a multilineEditText box. It's sort of being quarantined.
So It doesn't respond to messages like keyboard key presses.
Example :

LONG myDialog::Message(const BaseContainer &msg, BaseContainer &result)  
{  
  switch(msg.GetId())  
   {  
  
     case BFM_INPUT:   //A dialog/userarea receives this message if any mouse or keyboard input is received  
  
        if(msg.GetLong(BFM_INPUT_DEVICE) == BFM_INPUT_KEYBOARD) //If the input is from the keyboard  
         {  
           String input = msg.GetString(BFM_INPUT_ASC);   //Create a string type variable...   
           GePrint(input);                                //and assign it to the pressed key's unicode-text value  
           if(input == ".")   
           {  
             GePrint("period key was pressed");  
           }  
         }  
        break;  
  
   }  
  return GeDialog::Message(msg,result);  
}

Can I just request that the developers put better text wrangling within the MLTE(and maybe the other gui's) on their radar screens?
I don't know how many people are using this text editing stuff in their plugins. But better MLTE integration is something I would probably use often.

If you have meetings with the devs. Please tell the developer that made these two little message functions (GETCURSORPOS & SETCURSORPOS) that it was worth the time and effort to make them.
I use them often.

Thanks,

I just noticed the forum supports YouTube videos. That's cool!
Here's a video showing what I'm doing with the Multi text box gui:fibU-B-yzK4

This is the code I used to make it:

LONG myDialog::Message(const BaseContainer &msg, BaseContainer &result)  
{  
  String allWords;            //This will hold the entire text in the textbox  
  GetString(1001,allWords);    
  
  String lastWord;            //This will hold the last word that is typed into a text box  
  
  if (msg.GetId()==BFM_GETCURSORINFO)  
  {  
      String text;  
      if(GetString(1001, text))  
      {  
          LONG length = text.GetLength();  
          LONG pos = NULL;                                 //The variable that will hold the postion of the string  
          Bool lastSpace = text.FindLast(" ",&pos, -1);    //Find the last blank space and store it's position in the string  
          if(pos>0)                                        //If there is at least one empty space found  
          {  
            String lw = text.SubStr(pos+1, length - pos);  //Grab the last word (sub string)  
            lastWord = lw;  
          }  
      }  
  }      
  
  if (lastWord == "doc.")  
  {  
     String popupText;  
     LONG editX, editY, editW, editH;                          //Create variables to position the popup GUI  
          if(GetItemDim(1028, &editX, &editY, &editW, &editH)) //Queries a dialog control for its current size and position in pixels  
           {  
             if(Local2Screen(&editX, &editY))  
              {  
                BaseContainer entries;                        //Create a container to store the popup entries  
                entries.SetString(FIRST_POPUP_ID+0, "GetActiveDocument()");  
                entries.SetString(FIRST_POPUP_ID+1, "SetActiveDocument(BaseDocument* doc)");   
                entries.SetString(FIRST_POPUP_ID+2, "LoadDocument(const Filename& name, SCENEFILTER loadflags, BaseThread* thread)");  
                //Add more entries as needed  
                            
                LONG mypopup = ShowPopupMenu(NULL, editX, editY+(editH+300), entries); //Creates & positions the popup GUI  
                if(mypopup!=NULL)  
                 {  
                  popupText += entries.GetString(mypopup);     //Increment(step/loop) through each popup entry and get each value  
                  SetString(1001, allWords + popupText);       //Adds the user selected popup text into the textbox                      
                 }  
              }  
            }  
  }  
    
  return GeDialog::Message(msg,result);  
}

I was able to write this in R12.
I'm still a learner, and the code is probably not very good. But there's already just enough text handling code in the SDK's to at least create this kind of thing in a basic form. Even from a relative newbie like me.
But anything the developers can think of to make writing this kind of thing easier and more robust would be very cool.
