Fig. 3 shows the mutual process flow diagram of immediate menus according to the preferred embodiment of the invention, and step S106 specifically comprises:
Step S302, the functional sequence of the current execution of judgement user;
Step S304 is a condition with current functional sequence, the suitable immediate menus of retrieval from the immediate menus that is write down;
Step S306 initiatively shows the immediate menus that all are suitable;
Step S308 utilizes shown immediate menus to accept the mutual of user;
Step S310, functional sequence is carried out in response alternately, continues initiatively to provide suitable immediate menus in the process of implementation.
In addition, there is following problem in the prior art:
1) reciprocal process ossifys, can not free adjustment function flow process and setting;
3) can not import multiple parameters simultaneously;
4) in case given parameter just can't be changed the operation process, restart this step unless finish this operation.
Obviously, can free switching flow, the parallel a plurality of parameters of input and the parameter of revising input repeatedly by immediate menus.
Fig. 4 shows and responds mutual according to the preferred embodiment of the invention and process flow diagram execution functional sequence and continuation demonstration immediate menus, and step S310 response is carried out functional sequence alternately and specifically comprised:
Step S402, value from mutual;
Step S404, the utilization value is created change message;
Step S406 sends the scene of change message to current functional sequence;
Step S408 is flow process control option and desired parameters and the logical relation assignment between them, thereby carries out functional sequence that for example, the function scene is changed relevant variable and adjusted the function executing flow process according to the change result at the scene.
This has realized that after the user interactions immediate menus immediate menus can turn back to interactive information the function scene, and revises the value of associated variable.
The immediate menus that step S310 continues initiatively to provide suitable in the process of implementation specifically comprises:
Step S410 according to the logical relation between the immediate menus, judges which no longer shows in the immediate menus of current demonstration, hides the immediate menus that need not to show again.
S412 travels through current all immediate menus that do not show one by one.
Step S414 judges the immediate menus that traverses, and judges whether that be display condition with current display menu item to dependent variable.If be not display condition to dependent variable, then continue the next immediate menus item that does not show of traversal, otherwise carry out S416 with current display menu.
Step S416 judges whether the display condition of the immediate menus that traverses satisfies.If do not satisfy then the next immediate menus that does not show of continuation traversal.Otherwise, carry out S418.
Step S418 initiatively shows the immediate menus that all traverse, and accepts user interactions.
Preferably, initiatively provide the immediate menus that is fit to current functional sequence in the immediate menus that is write down specifically to comprise to the user: the situation of current functional sequence is reflected on the shown immediate menus in real time.
Preferably, the situation of current functional sequence is reflected on the shown immediate menus in real time specifically comprises: the data of monitoring current functional sequence; With data in real time be set to the change message in; To change message and send to immediate menus in real time; Upgrade the value of immediate menus; The associated variable object of immediate menus display update.
Situation when this function can be with program run is reflected on the immediate menus in real time.Give one example: make the curvature mark.The user selects an irregular curve, and its curvature is different in the value of every bit.When mark radius-of-curvature the time, concrete curvature value is along with the position of the point that moves on curve to be got of cursor is different and different.
The user can register a special immediate menus, is used for showing current radius-of-curvature value.In program operation process,, then oppositely send a change message if internal numeric changes.After the immediate menus response, upgrade current demonstration according to the value of associated variable.This can show running state of programs to the user intuitively, increases the friendly of man-machine interaction.
Fig. 5 according to the preferred embodiment of the present invention (for example shows
The snapshot of the immediate menus electronics chart board), when handling rectangle, bottom of screen ejects the immediate menus shown in the way automatically, use this immediate menus to carry out alternately, reduce interactive step widely, improved the dirigibility of feature operation, it is fairly obvious that the user is improved drawing efficiency.
As can be seen from the above description, the above embodiments of the present invention have realized following technique effect:
1, reduces interactive step, improve drawing efficiency.(for example realize according to the embodiment of the invention
The electronics chart board) utilizes immediate menus that current all possible programmed control option and numerical term are represented to the user, and default value is provided.The user is only switched necessary option according to actual conditions, perhaps input value, and current function running status is adjusted in system responses user's input automatically.Under the best situation, the user can finish mutual in one step alternately.
2, improve mutual dirigibility.(the CAXA for example that realizes according to the embodiment of the invention
The electronics chart board) immediate menus is continuously effective before function finishes.The user can be switched the immediate menus function choosing-item arbitrarily in the function operational process, change current function executing flow process.The user can also revise the numerical parameter that will import repeatedly.The result that final generation user wants.
Obviously, those skilled in the art should be understood that, above-mentioned each module of the present invention or each step can realize with the general calculation device, they can concentrate on the single calculation element, perhaps be distributed on the network that a plurality of calculation element forms, alternatively, they can be realized with the executable program code of calculation element, thereby, they can be stored in the memory storage and carry out by calculation element, perhaps they are made into each integrated circuit modules respectively, perhaps a plurality of modules in them or step are made into the single integrated circuit module and realize.Like this, the present invention is not restricted to any specific hardware and software combination.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
