Got so drunk for St. Patricks Day, I programmed something in graphics...
#1
Well don't get to excited. I may have fell off the SCREEN 0 wagon, temporarily, but this example is just a limited text input routine, in pure graphics mode. Because it allows for italicized and bold text, you'll need to download the attached zip folder and extract the fonts to whatever folder you decide to run this routine in.

You know my regular SCREEN 0 routines had url capabilities, but I only had the option of differentiating the links by color. No italics, and no underlining ability in a text mode screen. Now I could have used hardware graphics in SCREEN 0 to make a hybrid, instead of going all in on graphics, but like I stated in my message header, I got really, really drunk for the 17th. Oh, that reminds me. I used about a half a dozen line statements in the following code, but I'm not sure if any are straight.

Updated 3/22/24 to include more mouse features including clicking hypertext.

Updated 3/24/24 to include cut, copy, paste from keyboard.

Updated 3/28/24 to include ctrl + arrow keys to highlight words. Optimized highlighting for cursor and home/end keys. That was fun, but ctrl + arrows, I'll pass on optimizing that for now.

BIG UPDATE 4/2/24 to include POPUP window for cut/copy/paste/delete/select all/hypertext.

BIGGER UPDATE 4/7/24 to include text formatting buttons. Keys still work, too, and affect the buttons, accordingly.

4/9/24 Finished length restrictions, paste and universal button font changes.

BIGGEST UPDATE 4/19/24 Okay, so now we can make and save 1 page of text with up to 255 links on the page. Use the Enter key to go to a new line of text like an editor or IDE. Note there is no word wrap. Use CTRL + N for a new project, CTRL + S to save a project, and CTRL to O to open a saved project. This release does not check to see if you want to save your work before starting a new project. It also does not compare your present project with a saved version, so until I get around to addressing these and other file management issues, well, just be aware they are not yet available. Oh, I also removed link restrictions, so make sure if you want to go to a website, you start your input with http:// or https:// followed by the url like https://qb64phoenix.com. By removing that restriction we can now input things like "Notepad" and it will open notepad when clicked. Notepad and some other registered Windows apps can be found by SHELL without the inclusion of a drive and path, but other programs you want to launch, using this method, will require you include the drive and path followed by the app name.

Updated 4/20/24 Delete key can now delete a blank line to move lines below it up. Backspace cannot be used this way and will not be modified until wrap is added. Also, fixed one issue with multiple shell instances when dragging over a link.

Updated 4/22/24 Links can now be removed or edited. Right click on link and select to edit or remove.

Updated 4/24/24 Text scrolling with Enter key, arrow up/down keys, or mouse wheel.

Updated 5/25/24 Bug fix.

Code: (Select All)
Rem Note if code is expanded to include word wrap, the disallow length too long routines need to be updated to wrap routines.

Entering a URL does not produce any results. Otherwise the program works so far.

Insert image doesn't work.  Huh

Hmm, worked for me... but there's not enough meat on that plate!

You used F11 to enter the URL, and pressed the OK button, right?

But did you then press F12 to run the link?

1) Run the program. No need to type anything...
2) Press F11
3) Type in the URL
4) Click OK
5) When the popup closes, press F12 and your default browser should display the page.

Ok, it works with F11 and F12. However, this is not intuitive, because where do one have to confirm the link again? If one click OK the page opens. I assume 99.99% of all users think exactly that. You should change that.

Hm, . . . now enough?  Wink

Not enough plate for the meat!

It isn't at all intuitive, which is why I printed the key functions to the screen. This stage is just to get things going. Before I get really involved with any particular aspect of a project, I need to get my mind 100% made up as to how I want it to work; otherwise I could spend days re-coding it. There are several steps and conditions needed to make the mechanics suitable for use. Right now what I'm working on is transforming the above into subroutines and TYPE variables. When I see a project going bigger, I throw in that structure. That does waste a couple hours of my time, but if I started every project overly structured, it would take too long to get anywhere and to know if what I'm shooting for looks like it will be reasonably feasible.

Ok, that I understand. Goog luck!

Okay, finished with the refining. Now using TYPE declarations and subroutines. More code, but ultimately easier to manage. I updated the initial post, but left the original in case anyone wants to compare. Oh, I did do a bit of debugging, so it isn't exactly the same as it was when originally posted. I'm not going to bother addressing the bug fixes in the original post.

@Pete, with the corrected version it no longer works with F11 and F12, regardless of whether it is an image or a website.
It works with the old function. - Did I perhaps miss something?
