WPF: The toolbar is a keyboard trap



I have the following XAML code:


<ToolBarTray DockPanel.Dock="Top">
<ToolBar VerticalAlignment="Top">
<ComboBox x:Name="ComboboxFontname" ToolTip="Auswahlliste um Schriftart festzulegen" ItemsSource="{x:Static Fonts.SystemFontFamilies}" SelectedIndex="0" Width="200" GotFocus="ComboBox_GotFocus" LostFocus="ComboBox_LostFocus"/>
<ComboBox x:Name="ComboboxFontsize" ToolTip="Auswahlliste um Schriftgröße festzulegen" SelectedIndex="0" Width="45" GotFocus="ComboBox_GotFocus" LostFocus="ComboBox_LostFocus">
<ComboBoxItem Content="12"/>
<ComboBoxItem Content="14"/>
<ComboBoxItem Content="16"/>
<ComboBoxItem Content="18"/>
<ComboBoxItem Content="20"/>
<ComboBoxItem Content="22"/>
<ComboBoxItem Content="24"/>
<ComboBoxItem Content="26"/>
<ComboBoxItem Content="28"/>
</ComboBox>
<Label Name="lblSuchen" Content="_Suchen" Target="{Binding ElementName=edtSuchen}"/>
<TextBox Name="edtSuchen" Width="150" ToolTip="Bitte Suchbegriff eingeben. Suche Starten mit der Enter-Taste" KeyDown="edtSuchen_KeyPress" GotFocus="TextBox_GotFocus" LostFocus="TextBox_LostFocus"/>
<Label Name="lblErsetzen" Content="_Ersetzen" Target="{Binding ElementName=edtErsetzen}"/>
<TextBox Name="edtErsetzen" Width="150" ToolTip="Bitte Begriff eingeben, durch den der Suchbegriff ersetzt werden soll. Ersetzen Starten mit der Enter-Taste" KeyDown="edtErsetzen_KeyPress" GotFocus="TextBox_GotFocus" LostFocus="TextBox_LostFocus" IsTabStop="True" TabIndex="3" />
<Grid>
<CheckBox Name="ChkBarrierefrei" Content="Editor ba_rrierefrei" Margin="10" Click="ChkBarrierefrei_CheckedChanged" IsTabStop="True" TabIndex="4"/>
</Grid>
</ToolBar>
</ToolBarTray>
<TextBox Name="TBXEditor" DockPanel.Dock="Top" MinWidth="525" MinHeight="240" AcceptsReturn="True" FontSize="{Binding Path=SelectedValue.Content, ElementName=ComboboxFontsize}" FontFamily="{Binding Path=SelectedValue, ElementName=ComboboxFontname}" IsTabStop="True" TabIndex="5" GotFocus="TBXEditorBox_GotFocus" LostFocus="TBXEditorBox_LostFocus">
</TextBox>



If the checkbox "ChkBarrierefrei" has the focus and I press the tabulator key, then the textbox "TBXEditor" does not get the focus, but the comboxbox "ComboboxFontname". This means I can not get out of the toolbar with the Tab key. What can I do against it?

Try setting the ToolBarTray and/or ToolBar KeyboardNavigation.TabNavigation="Continue". The TextBox control should get focus now after the last CheckBox when you press the tab key.


KeyboardNavigation.TabNavigation="Continue"


CheckBox



Here's the MS link regarding the different enum values - KeyboardNavigationMode Enum

Makefile test if variable is not empty

Makefile test if variable is not empty In a makefile I'm trying to I've created this simplified makefile to demonstrate my problem. Neither make a or make b executes the body of the if, I don't understand why not. make a make b .PHONY: a b a: $(eval MY_VAR = $(shell echo whatever)) @echo MY_VAR is $(MY_VAR) $(info $(MY_VAR)) ifneq ($(strip $(MY_VAR)),) @echo "should be executed" endif @echo done b: $(eval MY_VAR = $(shell echo '')) @echo MY_VAR is $(MY_VAR) $(info $(MY_VAR)) ifneq ($(strip $(MY_VAR)),) @echo "should not be executed" endif @echo done I'm using $ make --version GNU Make 3.81 There are several problems, and misunderstandings. Your MY_VAR is a make variable, set it without a <tab> to its value, and no need to $(eval ...) . MY_VAR:=$(shell echo whatever) is enough. No <tab> before $(info ...) neither, this is make – Zelnes ...
