基本上我有一個tablelayoutpanel,它目前用於POS系統。 當我在按鈕控件上調用SetColumnSpan時,tablelayoutpanel會添加一行額外的行,並調整我的屏幕布局。.NET TableLayoutPanel
有沒有人遇到過這個?
面板中的每個可用空間都被分配一個空白按鈕,當屏幕處於編輯模式時,它們可以添加/編輯和刪除按鈕。 下面是應用按鈕更改的代碼。
編輯清理代碼有點
void button_MouseUp(object sender, EventArgs e)
{
try
{
TableLayoutPanelCellPosition pos = tableLayoutPanel1.GetCellPosition((Control) sender);
POSButton productButton = GetProductButton(sender);
tableLayoutPanel1.SuspendLayout();
if (productButton == null)
{
DeleteButton(sender, pos);
return;
}
productButton.Dock = DockStyle.Fill;
EditModeHookButton(productButton);
tableLayoutPanel1.Controls.Remove((Control) sender);
tableLayoutPanel1.Controls.Add(productButton, pos.Column, pos.Row);
if (productButton.TableRowSpan > 0)
tableLayoutPanel1.SetRowSpan(productButton, productButton.TableRowSpan);
if (productButton.TableColumnSpan > 0)
tableLayoutPanel1.SetColumnSpan(productButton, productButton.TableColumnSpan);
buttonManager.Save(tableLayoutPanel1);
tableLayoutPanel1.ResumeLayout();
}
catch(OperationCanceledException)
{
}
}
這裏是Button Manager的功能序列化的按鍵佈局。
public void Save(ScreenTabkeLayoutPanel panel)
{
List<ButtonSaveInfo> buttons = new List<ButtonSaveInfo>();
foreach (Control control in panel.Controls)
{
TableLayoutPanelCellPosition pos = panel.GetCellPosition(control);
ButtonSaveInfo info;
if (control is POSButton)
info = ((POSButton)control).ConvertToButtonInfo(pos);
else
info = control.ConvertToButtonInfo(pos);
buttons.Add(info);
}
AppDataSerializer.SaveBinary(buttons,buttonPath);
}
下面是加載/代碼填充屏幕與按鍵
private void LoadButtonsFromFile(ScreenTabkeLayoutPanel panel)
{
List<ButtonSaveInfo> buttons = AppDataSerializer.LoadBinary<List<ButtonSaveInfo>>(buttonPath);
panel.SuspendLayout();
foreach (ButtonSaveInfo info in buttons)
{
switch (info.ButtonType)
{
case (int) ButtonType.PRODUCT:
POSButton productButton = info.ConvertToPosButton();
wireButtonEvents(productButton);
panel.Controls.Add(productButton, info.ColumnIndex, info.RowIndex);
if (productButton.TableRowSpan > 0)
panel.SetRowSpan(productButton, productButton.TableRowSpan);
if (productButton.TableColumnSpan > 0)
panel.SetColumnSpan(productButton, productButton.TableColumnSpan);
break;
default:
Control control = BuildBlankButton();
wireButtonEvents(control);
panel.Controls.Add(control, info.ColumnIndex, info.RowIndex);
break;
}
}
FillEmptySpacesWillBlankButtons(panel);
panel.ResumeLayout();
}
在先進的感謝。
Coincoin謝謝你,你在哪裏現貨! – Jamie 2011-03-08 18:47:03
