![]() Let point = _mapToContentItem(, ) įlickable. this function maps the parent coordinate system to that of contentItem Property var parentMouseAreaPosition: Qt.point(0, 0) the current mouse position in the parent mouse area in parent coordinate system Map.parentMouseAreaPosition = Qt.point(mouse.x, mouse.y) ![]() the position must be updated on every position change After that, I have to use mapToItem to convert in the ntentItem coordinate system. This property role is to store the updated position of the mouse in the parent mouse area in the parent coordinate system. BLAST analysis of M34 sequence against mouse whole genome also showed maximum similarity to Y chromosome (> 97 identity) with few hits on the X. Inside draw (), pmouseX and pmouseY update only once per frame (once per trip through the draw () loop). ![]() You may find that pmouseX and pmouseY have different values when referenced inside of draw () and inside of mouse events like mousePressed () and mouseMoved (). The Type should be 'Mouse movement' by default, which means its 'mouse delta' Use Key / Mouse Button for any kind of buttons, Mouse Movement for mouse delta and scrollwheels, Joystick Axis for analog joystick axes and Window Movement for when the user shakes the window. I had to add a new property in my MapImage component. The system variable pmouseX always contains the horizontal position of the mouse in the frame previous to the current frame. Go into Edit -> Project Settings -> Input and check the settings for the Mouse X / Mouse Y axes. OnCurrentScaleChanged: updateFlickable(currentScale) Ĭonsole.log(mouseArea.mouseX, mouseArea.mouseY) // 0) currentScale = currentScale * (1 + scaleStep) Įlse currentScale = currentScale / (1 + scaleStep) įinally found a solution. Props.originalImageHeight = sourceSize.height Props.originalImageWidth = sourceSize.width HoverEnabled: true // this is required to use onPositionChanged I've made a minimal example available here or in a gist. When I'm zooming with the mouse wheel, zoom does not occur at the mouse position. Performing a different action depending on where the mouse is: when space v key pressed if <(mouse x) > 100> then repeat (10) change ghost v effect by (10) end wait (1) secs clear graphic effects else change y by (50) wait (0.5) secs change y by (-50) end.But this property seems to cause problems with mouseX and mouseY values taken from my updateFlickable function. I need to set the hoverEnabled property to true because I need onPositionChanged and others events. This is not the job of MapImage, so I really need this second MouseArea component. I want to use another MouseArea in the MapImage instance in main.qml (to be able to place objects using a Canvas but this is not important here). The MapImage component just handles image display, zooming and panning. This component uses Flickable and MouseArea components. I made a simplified MapImage component which allows to zoom and pan an image with the mouse.
