With Respect To ScrollBar To Rectangle

[Pradeep Kumar]

@p3c0
import QtQuick 2.4
import QtQuick.Window 2.2

Window {
id: win
visible: true
width: 700
height: 500
Rectangle
{
id: rect
width: t1.font.pixelSize * 50
height: t1.font.pixelSize * 10
color: "pink"
Text {
id: t1
text: "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaajjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjaaaaaaaaaaa"
}
}
}

as text size increases rectangle has to increase simultaneously , but in this case, its not increasing.

@p3c0

and one more thing it has to increase dynamically, with respect to text, please help.

[p3c0]

@Pradeep-Kumar.M hmm you meant length not size. Well in that case you will need get text length and bind it with some multiplier.
Its better to use a TextArea here. Isn't it ?

[Pradeep Kumar]

@p3c0

because data is coming from c++ class thats y, inserting it to rectangle directly . if so how to find text length, do we have length method for text, i didnt find it.

[p3c0]

@Pradeep-Kumar.M Yes. Use length.

@p3c0

thank u for example of scrollbar to rectangle, it worked, one issue in it is ,
when i drag down, scrollbar moving upwards, i dont want in that fashion, drag should be with respect to scrollbar, not opposite, please help me.

[p3c0]

@Pradeep-Kumar.M Must be some problem in your code. Try doing same as done in that example.

[Pradeep Kumar]

@p3c0

same thing i did it, will you please try, i want the scrollbar to have dragged with respect to mouse simulateonusly, not in opposite fashion, i tried,

[p3c0]

@Pradeep-Kumar.M Can you explain it w.r.t to that example ? That example works fine as expected.

[Pradeep Kumar]

@p3c0

code is working fine, but the thing is scrollbar has to move w.r.t to mouse, when i want to scroll, for example in this forum if u want to scroll up, u will move your mouse up, w.r.t to scrollbar, but in the example case moving mouse upwards, scrolling takes place downwards, i mean to say opposite direction.

[p3c0]

@Pradeep-Kumar.M Nope. If you scroll down the scrollbar moves down and ofcourse the image will go up and v.v. That's the intended behaviour.

[Pradeep Kumar]

@p3c0

hm k kk

[Pradeep Kumar]

@p3c0

and one more if we have implementation that works with keys press,
will it work for mouse area on clicked?.

[p3c0]

@Pradeep-Kumar.M Yes should work. Create a function and call that function when required.

[Pradeep Kumar]

@p3c0

you mean to say create function form ex: function sample()
{
// implementation
}

mouse area{
anchors.fill: id
onclicked
{
sample()
}
}

[p3c0]

@Pradeep-Kumar.M Yes, so that same function can be called from Keys and MouseArea. No need to duplicate the code.

[Pradeep Kumar]

@p3c0

what i taught was if there is implementation for keys event
, their will be different implementation for mousearea alse

[p3c0]

@Pradeep-Kumar.M Ofcourse you will need to define a MouseArea as well as Keys.onUpPressed. But if the code that moves the scrollbar is similar then no need to duplicate it. Just put it in the function and call that function.

[Pradeep Kumar]

@p3c0

ya got it,
keys.onuppressed,keys.ondownpressed, coming from .js file, will the same logic work for mousearea
{
} also .

[p3c0]

@Pradeep-Kumar.M

will the same logic work for mousearea

Depends upon the logic :)
