Embodiment

In order to make object of the present invention, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.

In embodiments of the present invention, for the distance length of track that can be by user's finger sliding, carry out accurate mobile cursor, the embodiment of the present invention has proposed a kind of based on font size, and the distance of sliding in conjunction with gesture is carried out the control of cursor.This scheme can solve in sliding process cursor cannot pinpoint problem, gives user with more smooth operation sense, increases user's satisfaction to terminal when carrying out copy editor.

Refer to Fig. 1, the realization flow of the method for the cursor location providing for the embodiment of the present invention, it comprises the following steps:

In step S101, when carrying out edit file, obtain the position of current cursor;

In step S102, the real-time current gesture sliding trace of supervisory user;

In embodiments of the present invention, the step of the gesture sliding trace that real-time supervisory user is current, is specially: obtain origin coordinates A and end coordinate B that touch point slides.

In step S103, according to described sliding trace, calculate the distance L of slip and the direction D of slip;

In embodiments of the present invention, refer to Fig. 2, if user slides into B point from A point:

The coordinate of A is (X1, Y1), and B point coordinate is (X2, Y2), and the distance L of sliding is:

$L=\sqrt{(X2-X1)(X2-X1)+(Y2-Y1)(Y2-Y1)}$

The direction parameter D sliding is:

$D=\frac{X2-X1}{|X2-X1|}$

When D<0, represent to slide left; During D>0, represent to slide to the right.

In step S104, obtain the size of current editing interface font;

In embodiments of the present invention, be mainly the width W of obtaining current editing interface font.

In step S105, according to the position of described current cursor, in conjunction with the size of the distance of described slip and the direction of slip and font, calculate the next position of described current cursor;

In embodiments of the present invention, the next position computing formula of cursor:

X+D*(L/W)

Wherein, current cursor present position coordinate is (x, y), and X value is the x coordinate of current cursor place screen; W can be converted to according to the font size of current system setting the width of font; More, round on can carrying out the result of calculation of this computing formula or lower rounding operation is to obtain the horizontal ordinate of the next position of cursor.When result of calculation is greater than 0 but while being less than the width of screen, ordinate is identical with the y value of current cursor; When result of calculation is less than 0, explanation is moved to the left and has exceeded left screen, and now the horizontal ordinate of next cursor is (width-X+D* (L/W)), the width that wherein width is screen, and ordinate is (y-1); When result of calculation X+D* (L/W) is greater than the width width of screen, cursor will move to descending, and now horizontal ordinate is (X+D* (L/W)-width), and ordinate is y+1.

In step S106, according to the next position of the cursor calculating, control cursor and move accordingly.

In embodiments of the present invention, before step S101, further comprising the steps of:

In step S1011, obtain user in the information that interface setting is set;

In step S1012, judge whether the information of described setting is to start the function of carrying out cursor location according to font size;

In step S1013, when judging, be to start the function of carrying out cursor location according to font size, Flag sign is set to 1, and writes in configuration file;

In step S1014, when judging, do not start the function of carrying out cursor location according to font size, Flag sign is set to 0, and writes in configuration file;

In step S1015, preserve described configuration file.

As one embodiment of the invention, described method is further comprising the steps of:

When receiving the instruction that enters edit file interface, read configuration file;

Judge the Flag sign in described configuration file;

When being designated 1, Flag represents to start the function of carrying out cursor location according to font size, execution step S101;

When Flag is designated 0, represent to be not activated the function of carrying out cursor location according to font size, by normal flow, operate.

Below by two embodiment, describe the operating process of the method for the cursor location that the embodiment of the present invention provides in detail.

Embodiment mono-:

Refer to Fig. 3, user is carrying out information editing:

Now user slides into B point from A point, supposes that the coordinate of A is (X1, Y1), and B point coordinate is (X2, Y2), course length

$L=\sqrt{(X2-X1)(X2-X1)+(Y2-Y1)(Y2-Y1)}$

The direction parameter D of unit

$D=\frac{X2-X1}{|X2-X1|}$

Now D is greater than 0, represents to slide to the right.

At this moment font size acquisition module need to carry out moving and determining set width W as follows:

1) obtain the font size W1 that current terminal arranges;

2) obtaining current cursor is expert at, because current, be to slide to the right, therefore whether there is special character (English, space, Tab, symbol etc.) if detecting current line cursor right side, place, and make character and sort out statistics, for example, in Fig. 3, after " space " word, add up: Chinese character zh_c=10, English character en_c=0, space blank_c=0, Tab character tab_c=0, symbol syb_c=0;

3), if there is special character (English, space, Tab, symbol etc.), obtain so at current language the lower corresponding font size W2 of each special character, W3, W4 are set ... Wn;

4), according to the data of the place line character of current statistics, calculate the width of font;

W=(zh_c*W1+en_c*W2+blank_c*W3+…+syb_c*W5)/(zh_c+en_c+blank_c+…+syb_c)

?

W=（10*W1+0*W2+0*W3+0*W4+0*W5）/（10+0+0+0+0）

The next position of cursor is so:

X+D*(L/W)

Embodiment bis-:

Refer to Fig. 4, user is carrying out information editing:

Now user slides into B point from A point, supposes that the coordinate of A is (X1, Y1), and B point coordinate is (X2, Y2), course length

$L=\sqrt{(X2-X1)(X2-X1)+(Y2-Y1)(Y2-Y1)}$

The direction parameter D of unit

$D=\frac{X2-X1}{|X2-X1|}$

Now D is greater than 0, represents to slide to the right.

At this moment font size acquisition module need to carry out moving and determining set width W as follows:

1) obtain the font size W1 that current terminal arranges;

2) obtaining current cursor is expert at, because current, be to slide to the right, therefore whether there is special character (English, space, TAB, symbol etc.) if detecting current line cursor right side, place, and make character and sort out statistics, for example, in Fig. 4, after " space " word, add up: Chinese character zh_c=8, English character en_c=2, space blank_c=0, TAB character tab_c=0, symbol syb_c=2;

3), if there is special character (English, space, TAB, symbol etc.), obtain so at current language the lower corresponding font size W2 of each special character, W3, W4 are set ... Wn;

4), according to the data of the place line character of current statistics, calculate the width of font

W=(zh_c*W1+en_c*W2+blank_c*W3+…+syb_c*W5)/(zh_c+en_c+blank_c+…+syb_c)

?

W=（8*W1+2*W2+0*W3+0*W4+2*W5）/（8+2+0+0+2）

The next position of cursor is so:

X+D*(L/W)

In above-mentioned two examples for special character only have English, space, TAB, symbol four kinds, this can carry out according to actual conditions the expansion of classification, can reach equally the effect described in the present embodiment.
