Embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are not limited thereto.
As shown in Figure 1, be the schematic flow sheet that disposal route first embodiment in region write by inventive touch screen, comprise the steps:
The touch point that S11, detection touch-screen input;
S12, according to the position of described touch point on described touch-screen, when judge draw described touch point be arranged in write region preset borderline region time, write region described in expansion;
Above-mentioned touch-screen writes the disposal route in region, detects in real time the touch point that touch-screen inputs, and pre-sets borderline region writing in region, according to the position of touch point, when touch point is positioned at borderline region, then automatically expands and write region; The present embodiment utilizes the positional information of touch point, achieves the automatic expansion of writing region, and user can write region not interrupting automatic expansion under the operation of writing.In the process, user does not need to be switched to the object that other patterns move the page to reach the expansion page more again, and user can write glibly, without the need to user's manual switchover operation, decreases the treatment scheme of writing region; Meanwhile, the present embodiment adopts the mode of writing regional expansion, and be write former the expansion that region is carried out, can not affect the relevance of page written contents, treatment effect is better.
Wherein, for step S11, detect the touch point that touch-screen inputs;
When user writing, monitor the touch event that touch-screen inputs, the touch point of pressing when detecting user writing, the position of record touch point.
For step S12, according to the position of described touch point on described touch-screen, when judging to show that described touch point is arranged in the borderline region write and preset in region, described in expansion, write region;
The position of described touch point is touch point coordinate on the touchscreen;
Describedly write region, can be a part of region on default touch-screen, also can be the screen of whole touch-screen;
Described borderline region, the predeterminable submarginal region for writing in region, borderline region is marked off writing in region by boundary line, the concrete size and shape of borderline region can be arranged according to actual needs, such as can be rectangle or other irregular figures, contrast the present embodiment does not do concrete restriction; As shown in Figure 2, region of writing in touch-screen is generally rectangular area, in Fig. 2, large rectangle ABDC is for writing region, boundary line in figure is four line segments EF, EG, FH and GH, take touch-screen as coordinate system, and the coordinate of line segment EF is x=20, the coordinate of line segment GH is x=2020, the coordinate of line segment EG is y=20, and the coordinate of line segment FH is y=2020, the position therefore judging touch point rapidly by coordinate figure and the relativeness of borderline region of writing region.
When judging that the position of current touch point is positioned at borderline region, namely the input trajectory of user is about to arrive the border of writing region, and now automatically expand and write region, what obtain newly-increased blank writes region.
Preferably, when writing region described in expansion, can expand according to the expansion direction of presetting in borderline region, also can expand according to the expansion speed preset, or other expansion modes such as the region of size are preset in expansion.
In one embodiment, the touch-screen described in the present embodiment mode writes the disposal route in region, when writing region described in expanding, also comprises step:
If detect, event is lifted in touch, then stop writing region described in expansion.
When region is write in expansion automatically, if user stops writing, then can correspondingly stop the expansion of writing region; Concrete, user stops the detection of writing, and lifts event by detecting whether triggers touch and determines; Therefore, when event is lifted in touch, then can judge that user does not write requirement at present, the expansion of writing region can be stopped, thus improve the treatment effect that touch-screen writes region.
