BOOL StatusLine::SetPercent (  INT32  NewPercent, BOOL  ClearBackground = FALSE, StringBase *  JobDescrip = NULL )

Sets the currently displayed percentage of the progress bar. The bar will be immediately redrawn to reflect the new value. Values outside the range 0..99 (inclusive) are clipped to 0 or 99. No redraw will be done if NewPercent equals the currently displayed value. Author: Jason_Williams (Xara Group Ltd) <camelotdev@xara.com> Date: 15/02/94 Parameters: NewPercent  - the new percentage value to be displayed by the progress bar [INPUTS] ClearBackground - Clears the entire bar background and redraws everything, rather than doing a (far more efficient) update of the bar/percentage alone. Use the default of FALSE unless absolutely necessary! JobDescrip - NULL, or a pointer to a new job description - pass NULL if this hasn't changed, as it makes a copy of the new string every time it is changed. If this is non-NULL, then the ClearBackground flag will be forced to TRUE to draw the new text. Parameters: -  [OUTPUTS] Returns: TRUE if it successfully makes the change. See also: CProgressBar::GetPercent; CProgressBar::Create Definition at line 1451 of file statline.cpp. { if (NewPercent < 0) NewPercent = 0; if (NewPercent > 99) NewPercent = 99; // If there's no change, don't bother updating if (JobDescrip == NULL && NewPercent == CurrentPercent) return(TRUE); CurrentPercent = NewPercent; String_64 PercentString; PercentString.MakePercent(CurrentPercent); SetStringGadgetValue(_R(IDC_SL_PROGRESSPERCENT), PercentString); SetLongGadgetValue(_R(IDC_SL_PROGRESSGAUGE), CurrentPercent); // If there is a new Job Description, change to use it if (JobDescrip != NULL) { delete JobDescription; JobDescription = new String_256(*JobDescrip); if (JobDescription) { SetStringGadgetValue(_R(IDC_SL_STATUSTEXT), ProgressShown?*JobDescription:StatusText); } else { SetStringGadgetValue(_R(IDC_SL_STATUSTEXT), ProgressShown?String_256(_T("")):StatusText); } InvalidateGadget(0, TRUE); // Repaint the whole bar PaintGadgetNow(0); } else { // Just repaint the gauge InvalidateGadget(_R(IDC_SL_PROGRESSGAUGE), ClearBackground); InvalidateGadget(_R(IDC_SL_PROGRESSPERCENT), ClearBackground); PaintGadgetNow(_R(IDC_SL_PROGRESSGAUGE)); PaintGadgetNow(_R(IDC_SL_PROGRESSPERCENT)); } return(TRUE); }
