CN102799441A - Method for realizing software interface sliding effect under WINDOWS system - Google Patents

Abstract

The invention relates to a method for realizing software interface sliding effect under a WINDOWS system. A child window is locked or unlocked by using an application program interface (API), and the API is manually invoked for redrawing after the sliding effect of the whole child window is completed, so that the problem of image tail or flickering caused by a window redrawing mechanism of the WINDOWS when the window slides is solved in the WINDOWS system.

Description

Realize the method for software interface slip special efficacy under a kind of WINDOWS system

Technical field

The present invention relates to realize under a kind of windows system method of software interface slip special efficacy.

Background technology

Computer user interface is meant the dialog interface between computing machine and its user, is the important component part of computer system.The development history of computing machine is not only processing speed of computing machine own and the memory capacity history that improves at full speed, and is to calculate the history that user interface is updated.Current software interface is rich and varied, and the characteristics of the maximum at these interfaces have provided friendly more interface to be different from common dialog box application program.In the WINDOWS system, when forms slide, can produce certain smear or flicker at present because the forms of WINDOWS redraw mechanism.

Summary of the invention

The present invention provides a kind of and when child form switches, is not easy to occur smear or flicker when Main form for the deficiency that overcomes above-mentioned prior art, and realizes the method for software interface slip special efficacy under the more smooth windows system of visual effect.

Realize the method for software interface slip special efficacy under a kind of windows system, specifically may further comprise the steps:

Step 1, will realize that the forms of sliding effect are called child form, the starting point of will sliding out that child form is positioned at is called initial position, and it is invisible that this child form is set, and the shown variable of this child form is made as false;

Step 2, open timer when beginning to slide earlier, the cycle of this timer is that child form moves to the needed time of target location from initial position;

During the slip special efficacy of step 3, beginning child form, child form is set, the shown variable of this child form is made as true for visible;

Step 4, in above-mentioned timing cycle, at interval a few tens of milliseconds is carried out the displacement of child form in Main form to the hundreds of millisecond, this child form is moved to the left x pixel, locks whole child form with win32 API before changing the child form position;

Whether the position of judging this child form immediately after step 5, the displacement of subwindow completion is in the target location; Read the distance value left of the left hand edge of child form with respect to the left hand edge of Main form; Judge whether to conform to,, represent that this child form has slided to finish if conform to and represent that then child form has reached the target location with threshold value; Jump to step 8, otherwise continue step 6;

Step 6, threshold value is deducted displacement pixel value x, so that in step 5, judge;

Step 7, return step 4;

Step 8, release child form are accomplished the slip special efficacy, and timer stops;

Step 9, whole child form is carried out once initiatively calling redrawing of API.

The present invention utilizes API that child form is carried out the locking and unlocking; After the slip special efficacy of accomplishing whole child form, manually calling API again redraws; Solved in the WINDOWS system; When forms slide,, the forms of WINDOWS produce the problem of certain smear or flicker because redrawing mechanism.

Description of drawings

Fig. 1 is a fundamental diagram of the present invention;

Fig. 2 is a workflow diagram of the present invention.

Below in conjunction with accompanying drawing and specific embodiment the present invention is made further detailed description.

Specific embodiment

Like Fig. 1, shown in 2, realize the method for software interface slip special efficacy under a kind of windows of the present invention system, specifically may further comprise the steps:

Step 1, will realize that the forms of sliding effect are called child form; The starting point of will sliding out that child form is positioned at is called initial position; If the shown variable of this child form is false, represent that this child form also normally shows, and this child form is set is invisible (invisible);

Step 2, open timer when beginning to slide earlier, the cycle of this timer is that child form moves to the needed time of target location from initial position;

During the slip special efficacy of step 3, beginning child form, with child form be made as visible (visible), and the shown variable of this child form is made as true;

Step 4, in above-mentioned timing cycle; A few tens of milliseconds is carried out the displacement of child form in Main form to the hundreds of millisecond at interval; This child form is moved to the left x pixel (occurrence is decided according to situation); Do not see sliding with naked eyes and be advisable, before changing the child form position, lock whole child form with win32 API, with guarantee child form on the throne move past in the journey because windows redraw machine-processed the photograph into smear;

Whether the position of judging this child form immediately after step 5, the displacement of subwindow completion is in the target location; Read the distance value left of the left hand edge of child form with respect to the left hand edge of Main form; Judge whether to conform to,, represent that this child form has slided to finish if conform to and represent that then child form has reached the target location with threshold value; Jump to step 8, otherwise continue step 6;

Step 6, threshold value is deducted displacement pixel value x, so that in step 5, judge;

Step 7, return step 4;

Step 8, release child form are accomplished the slip special efficacy, and timer stops;

Step 9, whole child form is carried out once initiatively calling redrawing of API, redraw smear so that guarantee not produce once more.

The above; It only is preferred embodiment of the present invention; Be not that technical scope of the present invention is done any restriction, so every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any trickle modification, equivalent variations and modification that above embodiment did.

Claims (1)

1. realize the method for software interface slip special efficacy under the windows system, it is characterized in that specifically may further comprise the steps:

Step 1, will realize that the forms of sliding effect are called child form, the starting point of will sliding out that child form is positioned at is called initial position, and it is invisible that this child form is set, and the shown variable of this child form is made as false;

Step 2, open timer when beginning to slide earlier, the cycle of this timer is that child form moves to the needed time of target location from initial position;

During the slip special efficacy of step 3, beginning child form, child form is set, the shown variable of this child form is made as true for visible;

Step 4, in above-mentioned timing cycle, at interval a few tens of milliseconds is carried out the displacement of child form in Main form to the hundreds of millisecond, this child form is moved to the left x pixel, locks whole child form with win32 API before changing the child form position;

Whether the position of judging this child form immediately after step 5, the displacement of subwindow completion is in the target location; Read the distance value left of the left hand edge of child form with respect to the left hand edge of Main form; Judge whether to conform to,, represent that this child form has slided to finish if conform to and represent that then child form has reached the target location with threshold value; Jump to step 8, otherwise continue step 6;

Step 6, threshold value is deducted displacement pixel value x, so that in step 5, judge;

Step 7, return step 4;

Step 8, release child form are accomplished the slip special efficacy, and timer stops;

Step 10, whole child form is carried out once initiatively calling redrawing of API.
