Note: Windows only app. (Saving you time reading if you only have Linux or Mac.)
For fun, I thought I'd start putting together an app that let's us paste text in a small persistent QB64 window. We can then click on line of text in the window, and insert it into another document, including a QB64 IDE window. So basically I'm making a multi-use clipboard app.
For now, it's bar bones, not goof proofed, but this is why I love this section of the boards where we can share stuff in the making. This is enough for now to demonstrate the basic mechanics. A lot more needs to be added to make it really worth using.
One challenge was a difference between apps like Notepad and QB64. _SCREENPRINT can be used for non-QB64 apps, but copying to highlighted text in the QB64 IDE results in the text being replaced with a "c" and paste has similar problems. I had to use a hack to get around this and used SENDEKY Windows API sub to open the QB64 Edit Menu and select "C" or "P" to get the operations to work properly. Not all that happy with it, but at least it works, and it is nice to include the IDE in the Sam-Clip app.
So how to separate the QB64 from other apps like Notepad? Hold Ctrl when highlighting or pasting to an app like Notepad and simple use the mouse without any key held to copy or paste in a QB64 IDE.
So to test it, try this....
1) Open Notepad and type some crap like, "Steve is brilliant." (We can so edit that later.)
2) Run Sam-Clip
3) Hold the Ctrl key and use your mouse to highlight part of the text like, "brilliant" When you release the left mouse button what you highlighted will be pasted into the Sam-Clip window.
3) Now press Enter a couple of times on notepad.
4) Next go to Sam-Clip and click on "brilliant" The text will be highlighted.
5) Go back to Notepad, hold down the Ctrl key, and left click where you want the text inserted. The word "brilliant" will be pasted into Notepad.
You can add more stuff to Sam-Clip, but for now it can't handle more than the window height. You can't same your additions yet, either.
You can bulk copy multiple lines of text to Sam-Clip, and bulk paste. .
Edit: Added Sam.clip.dat and Sam-clip.tmp database to save clipped selections.
Added ability to click where in the list to add a clipped line.
Edit: Added the ability to copy a bunch of text and keep it on Sam-Clip as a custom named [Header]. You right mouse hold on the [Header] and it will show you the contents.
Added the ability to click to highlight a [Header] and click the document. The contents of the [Header] will be paste into the document.
Added a bypass. If you hold Alt with a Sam-Clip entry highlighted, you can move about your doc and your Sam-Clip window will be grey and disengaged until you release the Alt key.
