Flex DateChooser - 周/周末的字体颜色差异

标签: flex datechooser

我希望在工作日和周末天的DateChooser / CalendarLayout中看到不同的颜色。我还想使用自定义样式名来实现这一点(例如:“weekColor”和“weekendColor”。

知道如何实现这一目标吗?

我花了几天时间才找到它。所以供将来参考:这是我的解决方案:

我扩展了DateChooser并在函数updateDisplayList上添加了一个覆盖(w:Number,h:Number)(在此函数中已经设置了SMTWTFS日期名称)。

在updateDisplayList中,您可以获取mx_internal :: dateGrid.dayBlockArrays [column] [row]包含CalendarLayout的所有值。在该数组/数组中,每列的第一行是SMTWTFS日之一。其他行是dayNumbers。一旦我发现它是一个确定周末日是什么并相应调整颜色的问题。如下所示:

override protected function updateDisplayList(w:Number, h:Number):void
    {
        super.updateDisplayList(w, h);



        // Now the dayBlocksArray has been filled. The Array looks as follows 
        // dayBlocksArray["rows"]["columns] .... therefor [i][0 (zero)] will always get the dayNames (SMTWTFS)
        // Compare the dayNames with the set this.dayNames (which always start with sunday) and find the weekend days
        var colIndex:uint = 0;
        var rowIndex:uint = 1; // The first row (SMTWTFS) is handled seperately
        var currentColumn:Array;
        var dayName:UITextField;
        var backgroundColor:uint = this.getStyle("dayNamesBackgroundColor");
        var isWeekendCol:Boolean = false;
        var currentTextFormat:TextFormat;

        // When the style is not found the default of white will be used.
        if (!backgroundColor)
        {
            backgroundColor = 0xFFFFFF;
        }

        for (colIndex; colIndex < 7; colIndex++)
        {
            // First determine if the first item in this row (SMTWTFS) is a week/weekend day
            currentColumn = mx_internal::dateGrid.dayBlocksArray[colIndex];
            dayName = currentColumn[0];

            // Determine if this is a weekend row
            // The dayNames array is fixed in the order of index 0 = sunday and index 6 = saturday. 
            // Therefor check of the text value of the current dayName is equal to either of 
            // those two. If it is we are dealing with a weekend column
            isWeekendCol = dayName.text == this.dayNames[0] || dayName.text == this.dayNames[6];

            if (isWeekendCol)
            {
                // Set the color
                currentTextFormat = dayName.getTextFormat();
                currentTextFormat.color = getStyle("weekendHeaderColor");
                dayName.setTextFormat(currentTextFormat);

                // Set the background color
                dayName.background = true;
                dayName.backgroundColor = backgroundColor;
            }
            else
            {
                currentTextFormat = dayName.getTextFormat();
                currentTextFormat.color = getStyle("weekHeaderColor");
                dayName.setTextFormat(currentTextFormat);

                // Set the background color
                dayName.background = true;
                dayName.backgroundColor = backgroundColor;
            }

            // Reset the rowIndex
            rowIndex = 1;

            // Now go through all the other rows of this column
            for (rowIndex; rowIndex < currentColumn.length; rowIndex++)
            {
                dayName = currentColumn[rowIndex];

                if (isWeekendCol)
                {
                    dayName.setColor(getStyle("weekendColor"));
                }
                else
                {
                    dayName.setColor(getStyle("weekColor"));
                }
            }
        } 
}

在CSS文件中,我添加了以下样式:

DateChooser {

cornerRadius:0;    headerColors:#FFFFFF,#FFFFFF;    todayColor:#00448c;    边框样式:无;    dropShadowEnabled:false;    fontFamily:myGeorgia;    dayNamesBackgroundColor:#ECECEC;    weekHeaderColor:#444444;    weekendHeaderColor:#DDDDDD;    weekColor:#00317F;    weekendColor:#DDDDDD;    headerStyleName:“dateChooserHeaderStyle”;
   comboBoxStyleName:“comboBoxStyleName”; }

这里最有趣的样式是自定义样式“dayNamesBackgroundColor”(用于为SMTWTFS集提供背景颜色)和自定义样式“weekendHeaderColor”,“weekHeaderColor”,“weekColor”,“weekendColor”

我在上面的方法中读取这些颜色,以完全控制周/周末颜色的差异,其中SMTWTFS设置可以获得与白天数不同的颜色

希望这将有助于其他人。花了我很多时间来弄明白:)

我为客户做了类似的事情。方法是扩展CalendarLayout类以接受这些样式并在相关日期修改样式。然后扩展DateChooser以接受相同的样式并将它们传递给新的CalendarLayout类。

这很乏味;你最有可能遇到私人变量问题;但它是可行的。
