[Solved] Need help implementing shift based selection
Edited by David Butler on
I am trying to implement Shift based selection that is common in most applications...

This is what I got so far:

I have it almost working well, but I'm running into a couple issues:
  1. When I shift left in the middle of text for the first time, its like it is skipping the first key press
  2. If I go back right after moving left, its like it keeps going left for a keystroke
  3. I can't right of my starting cursor...

Also, it would be nice if there was like a "cursor_moved" hook, also maybe a way to poll whether or not the shift key is down, i think something like that would make this a bit simpler...

I am probably missing something basic with the API, still trying to figure it out. Thanks in advance :)

Ok, oops, I figured out the strange behavior with the seemingly missing keystrokes, I needed to call cro_cont_selection(app); after moving the cursor :) but still having trouble going right of the starting position

Heyo
[Solved] Need help implementing shift based selection
Sorry I didn't catch any of your posts when I could actually be helpful!

This looks really neat. At some point I will be making an official system like this, so it's very helpful to have a look at what worked for you. So thanks for sharing!

If you have any suggestions for what would allow you to make your solution better or what would have made it easier, please let me know at [email protected]

I wouldn't be surprised if there were a better way, but this works for now until we get an official version :)

[Solved] Need help implementing shift based selection
How do I use the above code? Were do I put it?

I'm new to 4Coder but I am to embarrassed to admit/post that I can't figure out how to copy and paste LOL. As I have already posted another question that I think was to dumb to answer. But if I want to know I guess I need to post.

I'm too used to windows with shift+left/right arrow keys and ctrl c and v to copy and paste.

[Solved] Need help implementing shift based selection
To copy/cut/past you need to place the mark (ctrl + space by default) where you want the selection to start, move the cursor where you want the selection to end, and then use ctrl + c, ctrl + x, ctrl + v. 4coder default bindings.

To use the above code you need the paid version (4coder super).

You can create a new .h file and paste the code in it, until line 69 (and do not copy the "...").

To set up your bindings if you haven't already done it:
open 4coder_generated/remapping.h and copy the function fill_keys_default (or fill_keys_mac_default if you're on a Mac) in the file you created and rename the function (e.g. fill_keys_custom).

You'll need to merge the bindings from Croepha with the existing bindings. In the function you just copied search for "begin_map(context, mapid_file);". After that line you'll need to remove the lines that bind something that Croepha binds (e.g. remove the line that contains move_left, move_right...). Then paste the rest of the code, starting at line 69 (and do not copy the "...").

In 4coder_default_bindings.cpp you need to include the file you created and in the get_bindings function change the line default_keys(context); to fill_keys_custom(context); (or the name you chose).

Then run buildsuper.bat.

Edited by Zenn on
Yes I have 4Coder Super.

But I still can't copy & paste. When I try, I get a greyed out lined square around the first letter of text a want to copy and that's all I can get it to do.

*update*
I can do the copy and paste now. I did not know it was copying as their was no highlight and ctrl v is working now too. (no idea why or why working now)


So I tried posting in the code and run buildsuper.bat as per the post above.
I get these errors:

W:\4coder>W:\4coder\buildsuper.bat
4coder_metadata_generator.cpp
4coder_default_bindings.cpp

Could you copy the whole content of the file here ?
w:\4coder\edit.h(10) : warning C4189: 'was_active' : local variable is initialized but not referenced
The was_active variable isn't used. You can remove it from the function.

For the other error we need the code to help you.
Which version of visual studio are you using ?

[Solved] Need help implementing shift based selection
You can put it anywhere as long as the include path points to it.

For the first error, you can remove the line
1
bool was_active = cro_selection_active;

For the second error, replace the line
1
if (wrapped_func)

by
1
if (wrapped_func != 0)
