components - The qml default signal handler cannot work -

-

---question---

i create "textbtn" component , add signal "btnclicked" in it:

textbtn.qml

import qt 4.7  rectangle {     property alias btntext: showstr.text     width:100     height:30     border.color: "black"     border.width: 1     color: "white"     signal btnclicked()     //the default signal handler     onbtnclicked: console.log(btntext+" clicked.")     mousearea {         id: btnmousearea         anchors.fill: parent         onclicked: btnclicked()     }     text {         id: showstr         anchors.centerin: parent         color: "black"     } }

another component "menurow" contains 3 "textbtn"s follows:

menurow.qml

import qt 4.7  row {     spacing: 5     textbtn {         id: testbtn01         btntext: "test01"     }     textbtn {         id: testbtn02         btntext: "test02"     }     textbtn {         id: testbtn03         btntext: "test03"     } }

the default single handler "onbtnclicked" in "textbtn" should triggered when 1 of "textbtn"s in "menurow" clicked, doesn't. what's going on?

the related qml doc here: http://doc.qt.nokia.com/4.7/gettingstartedqml.html#basic-component-a-button

---development environment---

os: ubuntu 10.04

qt version: 4.7.0(use "qt-sdk-linux-x86-opensource-2010.05.1.bin" install qt sdk in default path "$home/qtsdk-2010.05/")

before running qml, source file "qtsetup.sh" set related paths,

$ source qtsetup.sh

qtsetup.sh

qtdir=$home/qtsdk-2010.05/qt/ path=$path:$qtdir/bin ld_library_path=$ld_library_path:$qtdir/lib

then run qml files "qmlviewer".

$ qmlviewer menurow.qml

a qmlviewer window triggered , shows "menurow". no error occurs. use mouse click "textbtn" in "menurow", nothing happens. (it should show message "text0x clicked" in terminal.)

i use qmlviewer run other examples , demos, seem work well. don't know why example cannot work.

the problem happens here (qmlviewer 4.7.0).

looks it's bug in qmlviewer, read follow-ups here.

if remove alias (btntext), signal work. (but proper solution update 4.7.1+)

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
