[SOLVED] Regarding Slider and Canvas

[Pradeep Kumar]

@p3c0

what do i do if i want to move upwards as well as downwards,
with respect to slider value

@Pradeep-Kumar.M
Same as how you update the progress bar. Bind the value. But you will need to deduce a formula which will move it precisely. For eg:

onValueChanged:
{
    progress.value = value;
    canvas.y = -value*160 //replace with your own formula
}

just to demonstrate how it works.

@Pradeep-Kumar.M By "existing QML Items" you mean the inbuilt QML items or your own custom defined items ?

[Pradeep Kumar]

@p3c0
our own user defined items.

[p3c0]

@Pradeep-Kumar.M I think yes. But I haven't used as such. Check out the following attached-properties for some information regarding it. Example here.

@p3c0

hello.
i got with respect to mouse implementaion,
can i have implementation of canvas with slider value with key up pressed, and key down pressed?. can you suggest.

[p3c0]

@Pradeep-Kumar.M As it doesn't return anything, you will need to keep a counting variable which will be increased and decreased on key up and down pressed (you will need to decide how much to increase or decrease at a time). Then assign this count (with some multiplier) value to y in similar way we did with slider.
