Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Fig. 1 shows the process flow diagram of the method for focus of organic chemical structural formula switching according to the embodiment of the present invention, comprising:
Step S10, monitors the input from keyboard;
Step S20, determines the focus in the organic chemical structural formula in the chemical typesetting interface of interactive mode;
Step S30, in response to input to switch focus.
In existing organic chemistry software for composing, the switching of focus is all lean on the operation of mouse to complete.Mouse action has its limitation, can not meet continuous print switching and carry out with editor simultaneously.And in the present embodiment, using the input from keyboard as the adjustment operation switching focus, the advantage that keyboard operation has mouse action not substitute is exactly fast, directly, continuously.In interactively chemical software for composing, the operation of keyboard can improve the efficiency of user greatly, eliminates the operation finding chemical bond or atom with mouse, facilitates user to make the various structure wanted, improve ease for use and the typesetting efficiency of chemical typesetting.
In addition, by the method achieving the ability being switched focus by linear method in reticulate texture, operation is made to become simple and fast.
Inventor finds, the rule of the switching focus of organic chemical structural formula is if focus is on atom, and so next step switching result must be chemical bond, and when focus is chemical bond, next step switching result must be atom.
Fig. 5 shows the schematic diagram of focus on chemical bond according to the preferred embodiment of the invention; Fig. 6 shows the different directionkeys focus possibility switching direction schematic diagram of Fig. 5; Fig. 7 shows the focus switching flow figure of Fig. 6.Preferably, when determine focus current be key time, step S30 comprises: if determine that input is the first button or key combination, then focus is switched to the atom of the first end of key; If determine that input is the second button or key combination, then focus is switched to the atom of the second end of key.When chemical bond is selected focus, switches focus and only have two selections, i.e. two atoms at chemical bond two ends.Because chemical bond can not depart from atom and independently exist, formed about it has two atoms mutually.
Preferably, first button or key combination comprise " ← " button, the atom of first end is atom to the left in two atoms of key connection, second button or key combination comprise " → " button, the atom of the second end is atom to the right in two atoms of key connection, wherein, if two atom right sides not to the left, then specify that on the lower side or larger atom is the atom of first end, another atom is the atom of the second end; And/or first button or key combination comprise " ↓ " button, the atom of first end is atom on the lower side in two atoms of key connection, second button or key combination comprise " ↑ " button, the atom of the second end is atom on the upper side in two atoms of key connection, wherein, if under two atoms are not on the upper side, then specify that to the left or larger atom is the atom of first end, another atom is the atom of the second end.Utilization orientation key adjusts, both intuitively, again fast.
Time current focus is chemical bond, obtain the coordinate of the atom at chemical bond two ends, according to the sensing of directionkeys, calculate coordinate figure maximum in the direction in which, the atom with this maximum coordinate value among is exactly the next focus atom switched.As shown in Figure 5, focus chemically key goes to the atomic time, because optional atom only has two, so the switching direction of the corresponding atom of both direction key meeting.Which reduces the chance switching and make mistakes.
In specific implementation, the coordinate of selected chemical bond two ends atom can be obtained, compare according to coordinate, judge that corresponding button chooses different atoms as the object of next focus.Left and right directions compares x coordinate, and above-below direction compares y coordinate, if the coordinate of some axles is identical, and the atoms of left side or upper side position.
Fig. 2 shows the situation schematic diagram of focus on single atom according to the preferred embodiment of the invention; The different directionkeys focus that Fig. 3 shows Fig. 2 may walk (namely switching) direction schematic diagram; Fig. 4 shows the focus switching result schematic diagram pressed after upward direction key of Fig. 3.Preferably, when determine focus current be the atomic time, in response to input comprise to switch focus:
If determine that input is the first button or key combination, then focus is switched to the key of the first direction of atom;
If determine that input is the second button or key combination, then focus is switched to the key of the second direction of atom;
If determine that input is the 3rd button or key combination, then focus is switched to the key of the third direction of atom;
If determine that input is the 4th button or key combination, then focus is switched to the key of the fourth direction of atom;
If determine that input is the 5th button or key combination, then focus is switched to the key in the 5th direction of atom;
If determine that input is the 6th button or key combination, then focus is switched to the key in the 6th direction of atom;
If determine that input is the 7th button or key combination, then focus is switched to the key in the 7th direction of atom;
If determine that input is the 8th button or key combination, then focus is switched to the key of the eighth direction of atom.
When atom is selected focus, the selection switching focus is unfixed, and can be 0 to any selection, the chemical bond that certain atomic energy connects in principle can not be a lot, can not more than eight.Map so this preferred embodiment is provided with eight buttons, be enough to realize the switching of focus from atom to chemical bond.
