In Eden Editor, display3denCopy can be accessed to offer the user a way to inspect and copy long texts.
Open the Display
The display can be opened in Eden Editor by executing
findDisplay 313 createDisplay "Display3denCopy";. While the display is mainly meant to be used inside the Editor it can also be used outside of it. To do so, just replace
313 with the IDD of your parent display.
Adding Custom Text
In order to display some text inside the edit box, one has to define the data. This is done via an uiNamespace variable like so:
uiNamespace setVariable ["Display3DENCopy_data", ["Text displayed as header", "Text the user can copy and inspect"]];
Adjusting the Control Height
Unfortunately, the display, or rather the code is bugged. You will noticed that for longer texts it will not properly adjust the control's height and therefore scrolling vertically will not work properly (Feedback Tracker Ticket).
However, this can be fixed like so:
//Set variable used by diplay3denCopy and create the display
uinamespace setVariable ["Display3DENCopy_data", [_header, _someLongText]];
private _display = findDisplay IDD_3DEN createDisplay "Display3denCopy";
//Adjust the height of the edit control properly
_ctrlEdit ctrlSetPositionH (ctrlTextHeight _ctrlEdit max (ctrlPosition _ctrlGroup # 3));
_ctrlEditFake ctrlSetPositionH (ctrlTextHeight _ctrlEditFake max (ctrlPosition _ctrlGroup # 3));
_ctrlEdit ctrlCommit 0;
_ctrlEditFake ctrlCommit 0;
