If that can be done, I can see in the future that the organizations like ACS would choose GChempaint as one of the standard file formats. In fact, it'd be nice if the default drawing values are the same as, let's say, ACS standard (american chemical society) or CS (Royal Chemical society the British one).
Or can you do the reversing of the angle sign by holding down Shift or Ctrl? so that you don't have remember which sign you have? (as it is, you have to remember how many times you've pressed Caps Lock odd numbers for reverse and even numbers for positive). Could you have the reverse as the default? They have a text mode ( too much mouse use, but intuitive) and the feature to just type in the atoms ( not intuitive but fast). Perhaps you could have this feature along side the system you already have in 0.8.x (ie the periodic table to choose from). I agree about my proposal being not intuitive. If you can build a theme with one of the standards inside, I'll add it to next version, and if it is not possible, or very difficult, I'll consider it as a bug and change GChemPaint internals so that it becomes possible. You might help a lot with that, I don't publish anything since I'm away from research since many years now, so I never really tried to conform with ACS or other standards. One issue is that GChemPaint uses pixels while ACS standards use points. There are a few things that are not straightforward, otherwise, I would have published ACS and CS themes along with 0.8.
I already thought about the settings issue. I'll probably have to find a better solution anyway. I fully agree that the lock trick is far from perfect, but I could not imagine a better way. Using the AltGr key is not perfect, since a user might want to use them at the same time as other modifiers, and it is almost impossible without a third hand. bond angle issue: it is not possible to use Ctrl, Shift or Alt keys, since they are already used by other features. element issue: we might have all three methods: the widget (slow), the contextual menu, and a one key method, perhaps using a modifier key? I also add shortcuts to change the bond length for the chain tool (0=auto, 1=10.) This is much more difficult to backport and needs much more testing, so not before 0.10 (unless you use 0.9.x). I'll backport that to the 0.8 branch, so that it should be operational in 0.8.2Ĭoncerning the bond issue, The AltGr key will also change the default orientation. If you type an uppercase character, you get a contextual menu with the elements whose symbols start with the typed character.Īs the default element is changed at the same time, you'll have to type 'c' again to come back to carbon as default. While this list might not be ideal, it should be very useful (and it is possible to make it customizable in the future). 26 elements can be selected this way, the list being:Ī: Al b: B c: C d: Na e: Se f: F g: Ge h: H i: I j: Ti k: K l: Li m: Mg n: N o: O p: P q: Si r: Br s: S t: Pt u: Cu v: V w: W x: Cl y:Y z: Zr. Fixed in HEAD: typing a lowercase character selects an element and change the underlying atom if any.
