Three different operations can be performed using the mouse, and the routines in this section serve all of them: 1) The press/release events are exposed to the application 2) Marking (press and move left button) and Pasting (press middle button) 3) The right mouse button is used from the configuration menu NOTE: During the marking process we attempt to keep the cursor within the bounds of the text as being displayed by setting the mouse position whenever the mouse has left the text area. Two reasons to do so: 1) QT does not allow the `grabMouse' to confine-to the TEWidget. Thus a `XGrapPointer' would have to be used instead. 2) Even if so, this would not help too much, since the text area of the TEWidget is normally not identical with it's bounds. The disadvantage of the current handling is, that the mouse can visibly leave the bounds of the widget and is then moved back. Because of the current construction, and the reasons mentioned above, we cannot do better without changing the overall construction. */ /*! */ void TEWidget::mousePressEvent(QMouseEvent* ev) { //printf("press [%d,%d] %d\n",ev->x()/font_w,ev->y()/font_h,ev->button()); if ( !contentsRect().contains(ev->pos()) ) return; QPoint tL = contentsRect().topLeft(); int tLx = tL.x(); int tLy = tL.y(); word_selection_mode = FALSE; //printf("press top left [%d,%d] by=%d\n",tLx,tLy, bY); if ( ev->button() == LeftButton) { QPoint pos = QPoint((ev->x()-tLx-blX)/font_w,(ev->y()-tLy-bY)/font_h); if ( ev->state() & ControlButton ) preserve_line_breaks = FALSE ; if (mouse_marks || (ev->state() & ShiftButton)) { emit clearSelectionSignal(); iPntSel = pntSel = pos; actSel = 1; // left mouse button pressed but nothing selected yet. grabMouse( /*crossCursor*/ ); // handle with care! } else { emit mouseSignal( 0, pos.x() + 1, pos.y() + 1 ); // left button } } if ( ev->button() == MidButton ) { emitSelection(); } if ( ev->button() == RightButton ) // Configure { emit configureRequest( this, ev->state()&(ShiftButton|ControlButton), ev->x(), ev->y() ); } } void TEWidget::mouseMoveEvent(QMouseEvent* ev) { // for auto-hiding the cursor, we need mouseTracking if (ev->state() == NoButton ) return; if (actSel == 0) return; // don't extend selection while pasting if (ev->state() & MidButton) return; //if ( !contentsRect().contains(ev->pos()) ) return; QPoint tL = contentsRect().topLeft(); int tLx = tL.x(); int tLy = tL.y(); int scroll = scrollbar->value(); // we're in the process of moving the mouse with the left button pressed // the mouse cursor will kept catched within the bounds of the text in // this widget. // Adjust position within text area bounds.
