我在Windows XP和Windows 7中遇到过标签控件的奇怪行为。在XP上的文本包含在tab上,而7中则没有。选项卡的问题是什么?
PS。非英文字母包裹
更新:这是一个自定义标签控件
以下是代码:
protected override void OnPaint(PaintEventArgs e)
{
DrawControl(e.Graphics);
}
internal void DrawControl(Graphics g)
{
if (!Visible)
return;
Brush br = new SolidBrush(clr_cl_area);
Brush brTab = new SolidBrush(clr_client);
Rectangle TabControlArea = ClientRectangle;
Rectangle TabArea = DisplayRectangle;
g.FillRectangle(br, TabControlArea);
g.FillRectangle(brTab, TabArea);
br.Dispose();
brTab.Dispose();
for (int i = 0; i < TabCount; i++)
DrawTab(g, TabPages[i], i, false);
if (_mouseTabIndex != null && _mouseTabIndex != _mouseTabIndexSave && _mouseTabIndex != SelectedIndex)
DrawTab(g, TabPages[(int)_mouseTabIndex], (int)_mouseTabIndex, true);
_mouseTabIndexSave = _mouseTabIndex;
}
internal void DrawTab(Graphics g, TabPage tabPage, int nIndex, bool mouseOverTab)
{
var recBounds = GetTabRect(nIndex);
SetBounds(ref recBounds);
var pt = SetPointsForTabFill(recBounds);
DrawTabBounds(g, recBounds);
FillTabl(g, recBounds, pt, false);
DrawTabSeparators(g, recBounds, nIndex, 0 /*y-bottom*/);
if (SelectedIndex == nIndex)
{
DrawTabGradient(g, recBounds, pt, nIndex,0/*width*/,1/*height*/);
DrawTabSeparators(g, recBounds, nIndex, 1 /*y-bottom*/);
}
if (mouseOverTab)
DrawTabGradient(g, recBounds, pt, nIndex, -2/*width*/, 0/*height*/);
DrawText(g, recBounds, tabPage.Text);
}
private void DrawText(Graphics g, Rectangle recBounds, string text)
{
var strFormat = new StringFormat();
strFormat.Alignment = strFormat.LineAlignment = StringAlignment.Center;
g.TextRenderingHint =
System.Drawing.Text.TextRenderingHint.ClearTypeGridFit;
//var fnt = new Font(MsFonts.familyPTSans, 8F, FontStyle.Regular, GraphicsUnit.Point, (byte)204);
var fnt = new Font("Arial", 8.25F, FontStyle.Regular, GraphicsUnit.Point, ((byte)(204)));
RectangleF tabTextArea = recBounds;
var br = new SolidBrush(clr_txt);
g.DrawString(text, fnt, br, tabTextArea, FormatString());
br.Dispose();
strFormat.Dispose();
fnt.Dispose();
}

为什么会这样?我不确定...我相信框架只使用底层的Windows API,因此如果Windows版本不同,.Net应用程序的外观/行为可能略有不同。我想知道是否有某种文化/字符串行为设置可以解决这个问题......
无论如何,这是我的问题的草率但有效的解决方案:只需在标签的文本中插入换行符(我不知道你是否可以从设计师那里做到这一点)。您可以使用自己的C#代码或设计人员的代码隐藏C#来完成此操作。您还必须使选项卡大小更大,以适应其他文本行。
// Set the size of the tabs. I multiply the default height by 2 for 2 lines
tabControl1.ItemSize = new System.Drawing.Size(77, 18 * 2);
// Force a line break within the string
tabControl1.Controls[0].Text = "Hello\r\nWorld";
